This article is about a/an rider in Kamen Rider Blade.
For the A. R. World version, see Mutsuki Kuroba.

Mutsuki Kamijo (上城 睦月 Kamijō Mutsuki) is Kamen Rider Leangle (仮面ライダーレンゲル Kamen Raidā Rengeru, Masked Rider Leangle), the fourth and final Rider to appear in the Kamen Rider Blade TV series, the strongest rider in Ace Form.


He is a troubled teenage highschool boy who was selected to become Leangle by the evil will of the Spider Undead (Category Ace of Clubs). There was an instance, however, when Go Kiryu, the initial candidate to become Kamen Rider Garren, took it from him and, with the will of the Spider Undead's parasite spiders, used the system to assault Kamen Riders Blade and Chalice. Although initially afraid of the dark when fighting the Mole Undead, Mutsuki overcame his fear when he saw the smiles on the peoples' faces he rescued.

Unlike Kamen Riders Blade and Garren, the first BOARD-created Riders, he gets no Jack form mainly because of a lack of a Rouze Absorber, but unseals other Undead to aid him, especially in the battle against the Keroberos Undead. This ability was removed from him when Joker was the only remaining Undead.

Mutsuki's high-class Undead seem to be the kindest of all the high-class Royals. His Category King is a pacifist, his Category Queen has a strong sense of honor and loyalty (and even has developed feelings for him), and his Category Jack is really laid back, and sometimes lazy, only fighting to defend himself. All of them tend not to fight, unless it was necessary. And with the help of his Category King and Queen, only then he is able to suppress the power of the Spider Undead and properly seal him. Mutsuki's girlfriend Nozomi provided a significant amount of help as well; though she couldn't assist with fully suppressing the Spider Undead's power, her love for Mutsuki enabled him to at least partially resist the mind control over the course of the series.

Mutsuki was able to figure out that Kamen Rider Chalice is really the 53rd Undead: Joker Undead and that he will become the strongest enemy when the rest of the Undead are sealed. In episode 31, he says to Garren that he will defeat him before that happens. Mutsuki at one time had all of Kamen Rider Chalice's sealed cards because of the Category King Caucacus Undead (in episode 35, he uses Chalices Spinning Dance to defeat the Jellyfish Undead). He tells Mutsuki that he should stop caring for his girlfriend if he really wanted to become stronger. He continued being controlled by the darkness of the Category Ace until episode 42 when he sealed the Tiger Undead who now encourages him to fight only for the sake of others.

Eventually, when Kenzaki is not able to defeat Joker/Hajime, Mutsuki decided that it was he who would seal the Joker. He battled Joker with all his might and despite that, he lost the battle. He was last seen with his girlfriend playing some basketball.

Missing Ace

In an alternate continuity, after Joker/Hajime was sealed, four years have passed and Mutsuki has tried to forget about being a Kamen Rider, working to have a normal life again. His first day of work turns out to be a disaster as both of his employers fight much to Mutsuki's dismay. This was abruptly put aside when he witnesses the Category Ace of Clubs and was compelled to transform into Kamen Rider Leangle. Together with Kenzaki, Tachibana, Kotaro, and Shiori, they figure out that Kamen Rider Glaive is really the Albino Joker that everyone is looking for. But he still manages to take the ancient power and use it on the Riders. But thanks to Hajime's sacrifice, he, Blade, and Garren were able to defeat the Albino Joker and save the world once again. He is last seen at Amane's fourteenth birthday party.

Kamen Rider Leangle in Legend War

Mutsuki Kamijo returned as Kamen Rider Leangle, teaming up with Sakuya Tachibana and Hajime Aikawa, as well as the rest of the Kamen Riders.

Leangle was also part of a group of reinforcement riders led by Akira Date/Kamen Rider Birth to aid the primary riders in defeating the Rock Great Leader. All the Kamen Riders got on their bikes and performed the All Rider Break attack which destroyed the Great Leader. OOO, Den-O, All Riders: Let's Go Kamen Riders

Mach Vs. Leangle & Chalice

When the history is changed, Mutsuki becomes one of the brainwashed Riders leading Shocker members.

But later, Mutsuki, alongside Sakuya, Hajime and Kenzaki, aided the riders against Shocker after they despise how Shocker act and also had themselves free from brainwashing after Takeshi Hongo alongside Hayato Ichimonji broke free from Shocker Tower.

Unfortunately, Leangle was among the Riders whose existence was erased by the Rider Robo. This fate, however, was rendered moot when the Rider Robo was finally destroyed by Shurikenjin TridoronIcon-crosswiki, restoring Chalice's place in history.

Video Game appearances

Kamen Rider Blade (video game)

Kamen Rider Leangle, with Blade, Garren, and Chalice, is playable in the Kamen Rider Blade video game.


The Leangle system was developed through tricks and manipulation by Isaka, the Peacock Undead, who needed the sealed Spider Undead to complete it. However, as later revealed, the Undead was not sealed properly and thus manipulated his users for his own agenda. For Mutsuki to change into Leangle, he has to insert the sealed ♣A: Change Spider card into his Leangle Buckle and position his buckle in front of his waist. The belt then expands automatically around his waist. Mutsuki makes a motion with his right hand across his face and says "Henshin!", then manually opens a portion of his buckle. The buckle announces "Open Up!" at this point. This would also cause a violet projection with a spider image to come out before him. Unlike Blade and Garren's method of transformation (running into their projections), Mutsuki's projection comes to him and completes his transformation into Leangle.

The same "Open Up" system would be used for the Rider Systems of the movie-only Riders Kamen Rider Glaive, Kamen Rider Lance and Kamen Rider Larc.

Similar to Garren's King Form, Leangle's Jack Form (ジャックフォーム Jakku Fōmu) is not shown in any of the shows except for the S.I.C. toy line and manga. This form is accessed through the ♣Q: Absorb Tiger and ♣J: Fusion Elephant cards. Unlike other Jack Forms, this form is not as maneuverable and lacks flight capability, but makes up for it in strength and defensive abilities. Leangle gains a chest plate with an engraved clover suit and is adorned with orichalcum tusk shoulder pads.

Evolution Tarantula
Tarantula Undead

Tarantula Undead

The Evolution Tarantula (エボルーショントランチュラ Evorushon Toranchura) is Leangle's King Form manifestation that resulted of the collaborating consciousness of Hikaru Jō and the pacifist Noboru Shima usurping control from the Spider Undead. A mind-controlled Mutsuki, attempting to initiate King Form with Garren's Rouze Absorber, inadvertently brought the combined presence of the Tiger & Tarantula Undead to the forefront and, with their combined wills, exorcised the Spider Undead from Mutsuki. In the ensuing battle against the released Spider Undead, Mutsuki morphed inbetween his human form and Shima's Undead form. With this form, along with Kenzaki's King Rouzer, enabled Shima-Mutsuki to defeat the Spider Undead and give it a 'Proper Seal'.

Behind the scenes


Mitsuki Kamijo is played by Takahiro Hojo (北条 隆博 Hōjō Takahiro). As Kamen Rider Leangle, his suit actors were Jiro Okamoto (岡元 次郎 Okamoto Jirō) and Jun Watanabe (渡辺 淳 Watanabe Jun).


  • The irony surrounding Mutsuki's weak will throughout most of the series despite Leangle being said to be strongest Rider has been the subject of mockery and parody, particularly within the Japanese fandom. It is most defined by a line he says in episode 42 as he battles the Tiger Undead: I am the strongest! (俺は最強だー! Ore wa saikyō da!)


  • Even before Mutsuki made his proper debut in the series, his character already appeared in the show's opening sequence right from the very first episode. However, it was edited such that his face was partially obscured by his hat, later showing his face in full after he made his debut.
  • As acknowledged in the hero change battle between Kamen Rider Decade and Gokai Red in Super Hero TaisenIcon-crosswiki, the Riders of Kamen Rider Blade share their card motifs with the heroesIcon-crosswiki from Shotaro Ishinomori's second and last Sentai series J.A.K.Q. DengekitaiIcon-crosswiki. Leangle's Clubs motif would make him Blade's equivalent of Clover KingIcon-crosswiki.
  • The name "Leangle" is the derived from 'leangle" (pronounced "liangle") which is an Aboriginal club/polearm-type weapon, which is related to the Minor Arcana version of the Suit of Clubs: the Suit of Wands.
  • The "Open Up" his belt does upon transformation is similar to that of Kamen Rider Super-1.
  • Mutsuki briefly stole Hajime's Heart deck, granting him access to Chalice's cards and attacks. Mutsuki used the 4, 5 and 6 of Hearts to perform Chalice' Spinning Dance attack, although he is not seen swiping the cards through the Leangle Rouzer and announces the attack himself. This may be due to the fact the Leangle Rouzer toy is unable to read cards from Chalice's Heart deck.
  • He is the only Rider in the main Blade series not to have any upgrade forms, only having his Jack and King forms being used in the SIC Saga. Although he attempted to transform into King Form within the television series using Garren's Rouze Absorber, the attempt failed to produce a new form due to the intervention of the Tarantula Undead.
  • Like a previous "tournament-style Rider series" had the franchise's first bat Rider, Leangle is the first associated with the spider, one of the most notable of all animals associated with Kamen Rider kaijin.
