Kosuke NitohEdit

Kosuke Nitoh Child

Kosuke as a child

Ever since he found a fossil near a lake as a child, Kosuke dreamed of becoming an archaeologist. Though his parents approved his ambition, his grandmother did not. Because she also scolded his adventurous behavior, Kosuke grew up thinking of her as strict and mean.

During one of his expeditions, Kosuke accidentally discovered the Beast Driver in ancient ruins. He also has an unusual liking for mayonnaise, constantly carrying a bottle of it with him and putting it on any food he eats, including doughnuts, oden and foods that already have mayo. Haruto and Shunpei refer to him as "Mayonnaise" because of this unique habit. When he finds Phantoms or Ghouls, he refers them as his "food" due to his ability and need to absorb Mana from them. It's shown that when Haruto finds Phantoms and tries to defeat them, Kosuke will get angry for interfering with his "feeding time". He also constantly leaves everyone around him speechless due to his tendency to interrupt others and express his thoughts without breaks.

While he originally saw Haruto as a nuisance, he was nevertheless willing to cure him of the poison injected into him by Manticore through the use of Dolphi Mantle's powers. After the incident with Oikawa, he gradually warms up to Haruto and sees him as a rival as well as a friend. Initially homeless and having to camp in places until he got chased away, he found a permanent spot to set up his camp at the roof of a building belonging to a woman whom he had once saved. Though, he still prefer to camp in many places.

Later, Kosuke revealed to Haruto, Shunpei, and Rinko that he received Kamen Rider Beast's powers from Beast Chimera. The Beast Chimera made a contract with Kosuke, granting Kosuke his magic. In exchange, Kosuke must absorb mana by defeating Phantoms and ghouls, or he will be eaten by Beast Chimera. Unlike Haruto who is knowledgeable about how Phantoms come about and operate, Kosuke initially knows nothing other than they can take human forms and he needs to eat them to survive. Later, Haruto offers Kosuke to get rid off Beast Chimera. However, Kosuke refuses and prefers to retain his powers and the status of being both a rival and an ally to Haruto. Even when he lost his Beast Driver. Kosuke refuses to destroy Chimera, as he won't find any important discovery, like Beast Chimera.


Rise of BeastEdit

Kosuke meets Haruto, Shunpei, and Rinko by chance during a Ghoul attack, when he was about to have his lunch. Kosuke is then mistaken as a Gate by Haruto. He decides to keep eye on him, much to Kosuke's chagrin, who sees Haruto's intervention to have "ruined his meal". However, the Phantom Manticore was also sent by Wiseman to attack Kosuke. Haruto transforms during the attack into Wizard to guard Kosuke, while Shunpei and Rinko takes Kosuke away from the scene.

Meanwhile, Kosuke, annoyed by the trio's attempt to keep him safe, ran off on his own and met a tarot fortune teller, whom he had taken an interest in. Kosuke then decide to let the fortune teller predict his future. The fortune teller tells Kosuke that his future is bleak, but Kosuke, due to his super positive mindset, retorts in a cheerful manner that wherever there is a danger, there is an opportunity waiting. He further irks the fortune teller by saying that even hope can be found within despair. The fortune teller is later revealed to be Manticore when Haruto arrives to save Kosuke, and chokes Kosuke as Manticore revealed himself.

Instead of feeling afraid like victims usually do, Kosuke is overjoyed instead. Due to Haruto's inability to fend off Manticore in his current state, and that Kosuke desperately "needs to feed", he transforms into Kamen Rider Beast. After making short work of the Ghouls (and devouring their magical energy), Kamen Rider Beast takes on Manticore and uses Chameleo Mantle to attack the Phantom unseen and gives him a hard time.

When Haruto tries to warn Kosuke of Manticore's poison attack, Kosuke was caught off-guard and the Phantom successfully poisons Kamen Rider Beast. However, Beast uses Dolphi Mantle shortly afterwards to cure himself and Haruto, further angering Manticore. Kamen Rider Beast then uses Falco Mantle and overpowers Manticore, and finally finishing the Phantom off with Falco Saber Strike and absorbing his Mana.

Though greeted by Haruto over his victory, Kosuke says nothing to reveal his origins as Kamen Rider Beast, but warns Haruto in a peculiar manner to never again interrupt his "meal". Another Magician

Magical FoodEdit

Kosuke was seen having his camp set up and enjoying a barbeque in a shrine, but was asked to leave by a temple elder. He then sees an artist, Hiroshi Oikawa, being attacked by the Hydra Phantom. Haruto also arrives at the scene and immediately transforms into Kamen Rider Wizard to engage the Phantom. Since he was the first to spot the phantom, Kosuke is annoyed by Haruto's interference yet again, and he tranforms into Kamen Rider Beast to proceed to fight Hydra Phantom as well. Upon realisation that he has to fight two magicians at once, the Hydra Phantom decided that his chance of coming on top is too slim and escapes in the midst of Wizard and Beast's bickering over who should fight the Phantom. Kosuke then accused Haruto, saying that it was his fault that his "meal" escaped again.

Taking a break at the donut shop, Haruto is curious about how Kosuke obtained Beast's powers. Kosuke then tells Haruto and friends about the story regarding him and Kamen Rider Beast. Apparently some time ago, Kosuke was an archeologist who went on expedition discovering some ancient ruins. Soon, he chanced upon the Beast Driver and met the Beast Chimera, who then forced a pact on the then dumb-founded Kosuke. To his utter surprise, several Ghouls were released within the cavern's vicinity, but he managed to transform for the very first time and defeat them as Kamen Rider Beast.

Some time later, Haruto is alerted that the Hydra Phantom is going to attack Hiroshi once again. On the other hand, while sending Griffin to look for the Phantom, Kosuke meets Misa, who is actually trying to make use of him by lying that Haruto is trying to destroy the Hydra Phantom so that he can absorb the phantom's mana, as well as telling him that Gates have Phantoms ready to be harvested in them, though expectedly leaving out the additional detail of require the Gate in question to fall into despair and die first. Acting on impulse and choosing to believe Medusa despite her being a Phantom, Kosuke rushed to the scene of battle quickly to stop Wizard. While Wizard in his Water Dragon form is engaging the Hydra Phantom, Kosuke then transforms into Kamen Rider Beast with the Buffa Mantle in an attempt to stop the battle. In the midst of the skirmish, Kosuke wants to know which side, Wizard or Phantom, can offer him a better deal in providing him the mana of Phantoms. The Magic of Food

Kosuke refuses Engage Ring

Kosuke refuses the Engage Ring from Haruto.

After battling Wizard Water Dragon, Kamen Rider Beast decides to retreat, but he kidnaps Hiroshi also. Kosuke then asks Oikawa how to unleash his inner Phantom. However, Oikawa leaves as he had no idea what Kosuke is referring to. In spite of that, Kosuke still accompanies Oikawa to his home. At Oikawa's home, Kosuke found out that the source of Oikawa's hope is his portrait of his late wife. Since his wife had passed away, Oikawa had stopped drawing due to the lack of encouragement. A moment later, Haruto, Rinko and Shunpei reached Oikawa's home. Kosuke then meets Haruto, who told him that Gates are not merely Phantom lures. Instead, they are humans with magical potential, and can be turned into Phantom if they fall into despair. Kosuke was dumbfounded by this, as he must keep eating Phantoms that conflicted with what Gates are. However, sacrificing a human to become the Phantoms will leave a bad aftertaste.

Later, Rinko and Shunpei proceeds to move Oikawa's wife picture to a safer location for fear that a Phantom may destroy his source of hope. On their way, they encountered Hydra Phantom and Ghouls. Rinko and Shunpei are helpless against the numerous Ghouls, as one of them took the opportunity to grab the picture. Hydra Phantom then destroys it in order to let Oikawa fall into despair. However, Kosuke arrives in fashion with a flying kick on one of the Ghouls. Kosuke then transforms into Kamen Rider Beast, and Haruto arrives and also changes to Wizard. The two then use Buffa Mantle and Land Style respectively to defeat the Ghouls. Wizard then decides to let Beast to take care the Underworld Phantom, while he battle Hydra Phantom. While Wizard Land Dragon defeats the Hydra Phantom, Beast encounters Bandersnatch Phantom in Oikawa's underworld. Kamen Rider Beast tried his best to defeat the Underworld Phantom, but then it became apparent that he is not so strong enough to do it alone. Hence, Beast summoned Beast Chimera, which overpowered the Bandersnatch Phantom without much effort. Beast Chimera then defeat the Underworld Phantom using its finishing attack.

Kosuke then meet Haruto, who thanked him for helping to defeat the Underworld Phantom. Haruto then offers Kosuke to get rid of his inner Phantom, the Beast Chimera. However, Kosuke refuses the Engage Ring at last second for two reasons. First, it is very awkward if a man takes a ring from another man. Second, Beast Chimera is very strong, it will leaves a bad aftertaste if Haruto dies battling his inner Phantom. In addition, Kosuke prefers staying as Haruto's eternal rival. However, the question is how long will Kosuke live. Today's Life, the Life of Tomorrow

After Wizard Flame Dragon is defeated, The White Wizard easily dispatches Beelzebub. White Wizard then states that Beast is an archetype Wizard. The White Wizard then disappears, before Beast could ask any questions. Rinko arrives to inform Kosuke and co. that Beelzebub can control people with his slugs. Kosuke and Shunpei rush to destroy the slugs. However, destroying the slugs proves useless as Beelzebub can control people directly. Kosuke then battles Beelzebub as Beast again, but is easily overpowered. However, Haruto arrives with Drago Timer to summon the Dragon Styles clones.

An enraged White Wizard prepares to kill Kosuke for ruining his plans, but he's saved by the sudden appearance of Haruto once he said that the hope (Haruto) is already in front of him. The Beginning of the Sabbath

Haruto's Last Hope and Search For Beast ChimeraEdit

When Gremin and his Ghouls attack the city, Kosuke tries to help and fights face to face with Gremlin even without his powers but is no match for the powerful Phantom. After Gremlin's defeat and the end of Phantom incident, Kosuke decided to search for Beast Chimera to know more about it's origins, with Yuzuru following him as his apprentice. The Last Hope

Lost WorldEdit

While fighting some Ghouls an indeterminate amount of time after he had obtained Hyper Mode and before the Beast Driver was destroyed and freeing Beast Chimera, he got dragged into a parallel world by the Magic Stone similar to the one that Haruto found. Haruto was surprised to see Kosuke as they meet Amadum. After Amadum tells of needing the Rider Rings, they decided to give him the Rider Rings. They return to the shop as they found their friends being trapped in the Mirror World. They enter the Mirror World when Wajima tells them that the Rings are with the children. As they manage to find the children, they are under attack by monsters, so Haruto and Kosuke transform. The children are surprised that they are Kamen Riders, but thinking that they are not trusted, so they summon Hibiki, Den-O, Kiva, Kuuga, Agito, and Blade. While fighting, a mysterious Rider arrives, finishing off the monsters as he introduced himself as Gaim. The Kamen Rider Rings

Gaim then return to his world before the portal closes, as Amadum gaining back the Rider Rings. Just before he attacks Haruto, Kosuke and the children along with his monsters, Kosuke gives Haruto two of his rings so he can escape with the children. As Kosuke sneaks into Amadum's lair, he already knows Kosuke is in the lair as he tells him what was his true plan in using the Rider Rings. After hearing his plan, Kosuke transforms into Beast to stop him, but Amadum is shown to be too powerful, as Beast started to dissolve into dust, presumably returned to his timeline.

Sengoku Movie BattleEdit

Beast, Wizard and the Armored Riders

Kosuke had recaptured Beast Chimera in the Beast Driver in order to research the belt and magic. With the appearance of the Ogre Phantom and the Fake Koyomi, Kosuke reaffirms his contract with Beast Chimera and becomes Beast again. While he manages to overpower the Fake Koyomi as Kamen Rider Wiseman but Ogre intervenes and escapes. Kosuke then goes out to search for the Fake Koyomi before Haruto as Wizard fights her and Beast faces Ogre again. Overpowered, he watches Haruto stop the Fake Koyomi by making the real Koyomi's feelings surface from within the Hope Ring before Ogre forces his way into Haruto's underworld and Beast has to fight more of the Carbuncle Phantoms. He finishes them off as Beast Hyper before going to Haruto's side and is relieved that he survived. Picking up the WizarSwordGun, Kosuke was captured by the Nepenthes Monster. Kosuke, along with Mitsuzane was then freed by Wizard as he joins the battle with the Riders. After the battle was over, Kosuke pluck a bunch of Helheim's fruits to feed Chimera, stating that he would rather eat the fruit than consuming mana, before he and Haruto teleported back to the main world.

Video Game appearancesEdit

Kamen Rider Battride WarEdit


Beast (Battride War).

Kamen Rider Beast appears as a Second Rider in the video game Kamen Rider Battride Wars. He is the one of the four second Neo-Heisei Riders who can be recruited into the Rider gang. He is first appeared as a brainwashed boss, until he was freed and unlike the movie Riders, he apparently made it way to join the other remaining main and secondary Neo-Heisei Riders, including surviving second Heisei Riders (such as Kaixa, IXA, and Garren) whom appeared as assist characters only.

In the game, Beast's mantle used for specials and finishing moves. While the mantles are unused for long, they will disappear. Ironically when Beast using his ultimate attack while wearing some of his mantles, the screen will shows a mantleless Beast.

His Hyper form is often usedas a separate DLC character, like Wizard Infinity Style to original Wizard, the form has no connection to original Beast. Same thing with Wizard, Beast Hyper is still voiced by Tasuku Nagase.

Unlike the other Riders whom has a bike (while Accel is a bike himself) Beast's Falco Mantle is used as his bike & moves like a normal walking inputs, as well as able to used dash attack, including an aerial attack, which the normal attacks can do in one hit (while without Bike Mode as original Beast can do 2-string normal aerial attacks like Blade, Decade and Wizard Infinity Style does). If playing Beast Hyper during Bike Mode, he will change into his Falco Mantle with the Bike Mode playterm being the same as original Beast. When Beast Hyper (suring Bike Mode as original Beast + Falco Mantle) deactivates Bike Mode or using original Beast's special aerial attack, Beast will revert back to Beast Hyper.

Kamen Rider Batton-LineEdit

Kamen Rider Beast becomes avaliable in the Rider roster in the online PC game, Kamen Rider Batton-Line, after defeating the boss at level 10.

Kamen Rider Travelers RecordEdit

Unlike Haruto, Kosuke is a much lighter character. He contrasts Haruto by being much more sensible and open to the others. Kosuke often places mayonnaise on all food, claiming that mayonnaise is the tastiest food. He even teases Haruto by placing mayonnaise on his doughnut; something that Haruto dislikes. Despite his lighter personality, Kosuke is a very stubborn guy and never listens to the others. He usually says "Don't say it!", to cut his conversation with the others. This can cause trouble for him and others, as in the first few episodes he appears in he often cuts off any conversation about Phantoms and Gates. He also doesn't take battles very seriously until the last few episodes, particularly after Yuzuru was kidnapped by the White Wizard. Despite claiming Haruto as a rival in the first place, Kosuke in the end helps Haruto in exterminating Phantoms. Kosuke is also easily or usually swayed by girls, like Rinko and Mayu. Despite this, his habit only happens for one person at a time.


Unlike Wizard, Beast doesn't use alternate forms to combat the Phantoms he consumes. Instead, he uses single shoulder mantle armaments called Mantles (マント Manto?) to help him gain an advantage over his foes.

Kamen Rider Beast's ending theme is entitled "BEASTBITE".

"Falco, Go: Fa-Fa-Fa-Falco!"
―Activation announcement[src]

The Falco Ring allows Beast to gain the orange Falco Mantle (ファルコマント Faruko Manto?), which gives him the ability to fly. This mode debuts in episode 17.

Falco Mantle is the second fastest Mantle at Beast's disposal, trumped only by the Dolphi Mantle. It is not usually used for battle, but rather for quick getaways or to finish off an already weakened opponent.

Appearances: Movie War Ultimatum, Episodes 17, 19, 26-27, 33-34, 37, 41, 43, 45

Chameleo Mantle
Beast Chameleon Mant

Chameleo Mantle

"Chameleo, Go: Cha-Cha-Cha-Cha-Chameleo!"
―Activation announcement[src]

The Chameleo Ring allows Beast to gain the green Chameleo Mantle (カメレオマント Kamereo Manto?), which gives him the ability to camouflage into his surroundings and become invisible, as well as utilize the Chameleo's tongue as a whip to either attack or constrict enemies. This mode debuts in episode 17.

Chameleo Mantle is only effective in fighting Ghouls and weaker Phantoms. Some Phantoms can see Beast, even in his camouflage state, making this Mantle rarely used in fighting Phantoms. It is also Beast's second slowest Mantle, only faster then the Buffa Mantle. Despite this, he can also become more nimble and faster when it comes to jumping and climbing with this Mantle on.

Appearances: Episodes 17, 20, 23-24, Super Hero Taisen Z, 30, 34, 37-38, 44, 48, 52, Sengoku Movie Battle

Buffa Mantle

Buffa Mantle

"Buffa, Go: Bu-Bu-Bububu-Buffa!"
―Activation announcement[src]

The Buffa Ring allows Beast to gain the red Buffa Mantle (バッファマント Baffa Manto?), which enhances his physical strength and endurance. This mode debuts in episode 18.

Buffa Mantle is Beast's strongest Mantle (in regards to physical attacks and durability). It can not only easily overpower Phantoms, but the Mantle can also be used to protect Beast from attacks. However, it is Beast's slowest Mantle, as well as the one that drains his mana the most. Though, this Mantle is often used, due to the great power of this Mantle, compared to the others.

In Ganbaride, he can initiate an attack with this Mantle called Beast Magic Buffa (ビーストマジック・バッファ Bīsuto Majikku Baffa?), where he dashes towards the enemy with incredible speed and rams into the target, causing them to explode.

Appearances: Episodes 18-21, 23-25, 27, Super Hero Taisen Z, 28, 30-31, 36, 39, 41, 45, 52, Sengoku Movie Battle

―Activation announcement[src]

The Dolphi Ring allows Beast to gain the purple Dolphi Mantle (ドルフィマント Dorufin Manto?), which gives him the ability to swim and emit purple magical energy to heal any ailment. This mode debuts in episode 17.

Dolphi Mantle is Beast's fastest Mantle. It grants him incredible swimming speed, as well as the ability to cure injuries or poisons. However, the healing ability can drain Beast's mana quickly, making it a last resort tactic. This Mantle is rarely used, as Beast rarely needs to heal the others and healing costs more mana.

In Ganbaride, he can initiate an attack with this Mantle called Beast Magic Dolphi (ビーストマジック・ドルフィ Bīsuto Majikku Dorufi?), where he shoots a current of water from the Dolphi Mantle at the target that explodes into a blast of water.

Appearances: Episodes 17, 26, 35

  • Height: 208 cm.
  • Weight: 99 kg.

Rider Stats

  • Punching Power: 15 tons
  • Kicking Power: 20.3 tons
  • Highest Jump: 30 m.
  • Fastest Speed: 100 m. per 4.0 seconds

Beast Hyper (ビーストハイパー Bīsuto Haipā?) is the ultimate form of Kamen Rider Beast, which is accessed through the Hyper Ring. This form debuts in episode 29.

In this form, Beast's kicking and punching power has nearly doubled from his standard form, making him a force to be reckoned with. He has now fringes on his forearms that are both offensive and defensive weapons. However, he loses some of his maximum jumping height as a result, as well as the ability to access his Mantles. On another note, his speed has only been heightened slightly. Before transforming, Beast regains mana through a surge of mana while transforming into Hyper.

His weapon in this form is the Mirage Magnum. When Beast Hyper opens the mouth of the Hyper Ring and inserts it into the Mirage Magnum's ring slot, he can initiate an attack called Shooting Mirage (シューティングミラージュ Shūtingu Mirāju?), where Beast Hyper shoots Beast Chimera as a beam of energy to destroy the enemy.

If Beast enters a Gate's Underworld while in this form, he can summon Beast Chimera by releasing him through force of will instead of using the Chimarise Ring. However, this will revert Beast back to his original form.

Appearances: Episodes 29-33, 35, 39, 41, 43, 45-47, 49, 52, Sengoku Movie Battle

Wizard Style

"Land, Dragon: Dan Den Don Zu Dogon, Dan Den Dogon!"
―Transformation announcement[src]

Wizard Style (ウィザードスタイル Wizādo Sutairu?) is a special form exclusive to Kamen Rider Wizard Hyper Battle DVD: Showtime with the Dance Ring, which is accessed when Beast scans Kamen Rider Wizard's Land Dragon Ring on the Beast Driver after the latter took his Buffa Ring.

In this form, Beast dons the Land Overcoat (ランドオーバーコート, Rando Ōbākōto) from Wizard's Land Dragon form and is equipped with the Drago Hell Claws (ドラゴヘルクロー Dorago Heru Kurō?) on his arms.

This form is able to use the cleaving capabilities of the Drago Hell Claws. Its finishing move is the Dragon Beast Torn (ドラゴンビーストトーン Doragon Bīsuto Tōn?), which involves Beast charging at an enemy before going through a Magical Portal that forms WizarDragon to destroy the Phantom.

As revealed in episode 24, Beast is unable to use Wizard's rings. In this case, how Beast is able to do this is unknown.

In a feature exclusive to the S.H. Figuarts, Beast can be armed with Two Mantles (any combination). He can also use a single or Two Mantles in Hyper.

  • "Now, the main dish!" - Beast's catchphrase, before executing a finisher.
  • "Now it's breakfast time" - pre-battle catchphrase said in the mornings when he has not eaten yet.
  • "A pinch is a chance" - a catchphase usually said when he finds himself in trouble.

Rider MachineEdit

  • He is the first secondary rider to be colored gold, and the fourth in general after Agito, Odin, and Caucasus.
  • His transformation poses and actions are similar to Black and ZX.
  • He is similar to Kamen Rider OOO in his Latorartar Combo, as they both are yellow/gold in color and have a lion motif.
  • Him using a Griffin as a PlaMonster is probably alluding to how Griffins have the same relationship with Chimeras as they have the torso of a lion.
  • Beast's relationship to Beast Chimera is similar to the relationship with the Kamen Riders from Kamen Rider Ryuki and their Contract Monsters.
  • Beast's ability to absorb mana from the Phantoms echoes Beet and Stag Buster, the additional heroes of Tokumei Sentai Go-Busters, the first Super Sentai show that Wizard aired alongside, whose respective mechas (BC-04 and SJ-05) are able to siphon Enetron from Enetron tanks and Vaglass MegaZords.
  • His unusual liking to mayonnaise is similar to Toshiro Hijikata from Gintama.
  • Kosuke is the second individual to be mistaken as a Gate after being attacked by Phantoms, with the first being Satoshi Ishii from episodes 14 and 15.
  • According to Kosuke's actor, he wanted to call the Phantoms "Yummies" because of how Kosuke eats their mana, but the director told him no, in order to avoid confusion with the monsters from Kamen Rider OOO.
  • He's the only Kamen Rider to share his Final Form's name with that of the Final Form of a Rider from a previous series, that being the Primary and Secondary Riders from Kamen Rider Kabuto.
    • Coincidentally, he is the first Secondary Rider since Gatack to receive a Hyper Battle DVD-exclusive form.
  • The color scheme and design of Beast Hyper is strikingly similar to "Sea Jetter KaitoIcon-crosswiki" a local hero mascot of a theme park whose costume design came from early drafts from Shotaro Ishinomori.
    • The difference is that Sea Jetter Kaito is cyan and Beast Hyper is regular blue.
    • The blue/gold color scheme of Beast Hyper is also the same as the Final Form of his Secondary Rider predecessor, Kamen Rider Meteor Storm.
  • Similar to how Wizard's different Styles each involve a different mystical element, Beast's different Mantles involve different biomes of the Earth.
    • Falco: Sky
    • Chameleo: Forest
    • Buffa: Land
    • Dolphi: Sea
  • Beast is the only Wizard Rider that has the standard compound eyes of the Kamen Riders, while the other Wizard Riders have rarely-used visor eyes, shaped like jewels.
  • Since the Beast Driver was created in ancient times, it is possible that there was a previous Kamen Rider Beast before Nitoh, like with Kuuga and OOO.
  • Four of the five animals associated with Beast are four of the five animals associated with the LivemenIcon-crosswiki.
  • While various Secondary and beyond Riders have assumed new forms (normally Final Forms) since G3 and Gills in Kamen Rider Agito, Beast is the first to truly alternate between different forms (though technically they are attachments) just as main Riders have.
  • He is the second rider (not counting Gatack) to have a Final Form named Hyper.
  • Nitoh owns a mirror that let him spot Phantoms through the eyes of the Griffin PlaMonster, similar to Koyomi's crystal ball.
  • In the end of Kamen Rider × Kamen Rider Gaim & Wizard: The Fateful Sengoku Movie Battle, Kosuke is shown to have plucked some of the fruit of Helheim for Beast Chimera. However Kosuke never made such indication to have been tempted to eat a fruit. This may indicate that if one wears any transformation Driver, then that temptation will never come.
