Kosuke Nitoh (仁藤 攻介 Nitō Kōsuke) is a student archaeologist who discovered the Phantom Beast Chimera and became Kamen Rider Beast (仮面ライダービースト Kamen Raidā Bīsuto). Referred to as "the ancient magician" (古の魔法使い Inishie no Mahōtsukai) by the Wiseman due to his ancient Belt, he needs to absorb the mana of the defeated Phantoms in order to regain his strength.


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.


He is young man from the Fukui Prefecture who is rather optimistic, often believing that pinches and chances are sides of the same coin. He has a gigantic appetite and an unusual liking to mayonnaise, putting it on everything he eats, including doughnuts. He originally lived with his grandmother before he became a student archaeologist. During an expedition, Nito found the Beast Driver and broke the seal holding a horde of Ghouls at bay. Forced to become Kamen Rider Beast to defeat the monsters, Nitoh learns he unknowingly forged a pact with the Phantom Beast Chimera and must now consume other Phantoms for their magical energies to keep the Phantom fed, as if it dies, so will he. Through a misunderstanding as to how Kamen Rider Wizard functions in regards to absorbing and replenishing magical power, he labels Haruto his "eternal rival" when they first meet after Nito was targeted by Manticore on the assumption that he was a Gate. Despite it being possible for Haruto to simply use an Engage Wizard Ring to enter Nitoh's Underworld and destroy Beast Chimera, Nito initially refuses on the grounds that his Phantom would be too strong for Kamen Rider Wizard to handle and the experience would "leave a bad taste." Nitoh later explains that as an archeologist, he wishes to learn more about the Phantoms, the Beast Driver, and the Wizard Rings, believing he will never make as important a discovery as Beast Chimera again.

When Nitoh attempts to end the second Sabbath, he is overpowered by Fueki. In risky gambit that could have killed him, Nito broke the Beast Driver to release Beast Chimera so he can devour all of the excess magical energies generated by the Sabbath to negate the ritual. In appreciation, the idea of eating not amusing, Beast Chimera spares Nitoh's life and frees him from their pact before leaving. Despite being a normal human again, Nitoh aided Haruto during the final battle. Once the Phantoms are finally defeated, taking Yuzuru as an apprentice, Nito decides to find Beast Chimera to learn more about the ancient Phantom. Nitoh eventually recaptures Chimera and seals it on the Beast Driver once more, but is forced to transform into Kamen Rider Beast once more to confront the Phantom Ogre and a copy of Koyomi he created using the Hope Wizard Ring, despite knowing that without Phantoms to consume, he will be eventually eaten by Chimera. After Ogre is defeated, he is consumed by the Nepenthes Inhumanoid under Kamen Rider Bujin Gaim's orders. Nitoh is later rescued by Kamen Riders Gaim and Wizard and assists them to defeat Bujin Gaim and in the occasion, learns that he can feed Chimera not only with Phantoms but with fruits from the Helheim Forest as well.

Video Game appearances

Kamen Rider: Summonride

Kamen Rider Beast appears as a Partner Chip in the video game Kamen Rider Summonride. Beast is a Luck (Yellow) Nakamaride chip, and acts as a light combat partner. His most common attacks are using the Chameleo Mantle.

Kamen Rider: Battride War

Kamen Rider Beast appears as a Second Rider in the video game Kamen Rider: Battride War. 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 used as a separate DLC character, similar to Wizard's Infinity Style. Beast Hyper, like Beast, is 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 (during 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-Line

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

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.

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.

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

Falco Mantle

"Falco, Go: Fa-Fa-Fa-Falco! (Falcon wings flapping)"
―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, Wizard Episode 17, 19, 26-27, 33-34, 37, 41, 43, 45, Wizard in Magic Land

Chameleo Mantle
KR-Beast ChameleoMantle

Chameleo Mantle

"Chameleo, Go: Cha-Cha-Cha-Cha-Chameleo! (Chamelon tongue flicking)"
―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: Wizard Episode 17, 20, 23-24, Super Hero Taisen ZIcon-crosswiki, Wizard 30, 34, 37, 38, 44, Wizard in Magic Land, Wizard 48, 52, The Fateful Sengoku Movie Battle

Buffa Mantle
KR-Beast BuffaMantle

Buffa Mantle

"Buffa, Go: Bu-Bu-Bububu-Buffa! (Buffalo grunts)"
―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: Wizard Episodes 18-19, 21, 23-25, 27, Super Hero Taisen ZIcon-crosswiki, Wizard 28, 30-31, 36, 39, 41, 45, Wizard in Magic Land, Wizard 52, The Fateful Sengoku Movie Battle

Dolphi Mantle

"Dolphi, Go: Do-Do-Do-Do-Dolphi! (Dolphin squeaks)"
―Activation announcement[src]

The Dolphi Ring allows Beast to gain the purple Dolphi Mantle (ドルフィマント Dorufi 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: Wizard Episode 17, 26, 35, Wizard in Magic Land

Beast Hyper
KR-Beast Hyper

Beast Hyper

"Hyper, Go: Hy-Hy-Hy-Hyper! (Lion roar)"
―Transformation announcement[src]
  • Height: 208 cm.
  • Weight: 99 kg.

Rider Stats

  • Punching Power: 12 t.
  • Kicking Power: 20.3 t.
  • Maximum Jump Height: 30 m.
  • Maximum Running Speed: 100 m. per 4.5 sec.

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 now has 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: Wizard Episodes 29-33, 35, 39, 41, 43, 45, Wizard in Magic Land, Wizard 46-47, 49, 52, The Fateful Sengoku Movie Battle

Wizard Style
KR-Beast WizardStyle

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 Wizard 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.

Rider Machine

Beast on bicycle

Beast riding on a bicycle.

  • Beast has not been shown to have a motorcycle, making him the second secondary Rider to lack a Rider Machine (the first being Diend).
    • This is teased in episode 40, where Beast borrows a bicycle to fight the Ghouls.
    • In the video game Kamen Rider: Battride War, the Falco Mantle is used in the place of a bike, further poking fun at Beast's situation.


  • 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.
    • Surprisingly, Beast and OOO Latorartar Combo appear together in Where is Beast?.
  • 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 BeetIcon-crosswiki and Stag BusterIcon-crosswiki, the additional heroes of Tokumei Sentai Go-BustersIcon-crosswiki, the first Super Sentai show that Wizard aired alongside, whose respective mechas (BC-04Icon-crosswiki and SJ-05Icon-crosswiki) are able to siphon EnetronIcon-crosswiki from Enetron tanks and VaglassIcon-crosswiki MegaZordsIcon-crosswiki.
  • 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 Riders 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.
