"I am the man who will replace the gods with a slash of my sword, Tsurugi Kamishiro!"
―Tsurugi's usual battle phrase[src]

Tsurugi Kamishiro (神代 剣 Kamishiro Tsurugi) was Kamen Rider Sasword (仮面ライダーサソード Kamen Raidā Sasōdo, Masked Rider Sasword), one of the characters in Kamen Rider Kabuto.


TV series

In truth, the real Tsurugi was killed on the same day as his sister by the Scorpio Worm. Moments before his death, the Scorpio Worm chose to mimic him. However through impossible odds, Tsurugi's arrogant nature and personality overpowered the Scorpio Worm's own, leading him to believe he was in fact Tsurugi Kamishiro, completely unaware of his Worm identity or that he had killed his sister. Jiiya later revealed he had been aware of his master's true identity, but believed it best to withhold the information in the hopes the Scorpio Worm would never regain control and his master would continue to exist, one way or another. Shortly afterwards through unknown means, Tsurugi came into contact with the Sasword Zecter and accepted his role as Kamen Rider Sasword with the goal of exterminating every last Worm.

Few episodes after his debut episodes, Tsurugi somehow turns into the comic relief in this series. Many episodes involve him trying to do some daily duty in a very ridiculous way, usually with his special theme playing. Tsurugi has only recently learned (from both Gon and Jiiya) that the Discabil family fortune is no more, and this confounded him deeply, so he is working hard to rebuild it. He now works at the Soba shop where Misaki always visit. He has a crush on her, to which she feels annoyed. In episode 26, Tsurugi meets the Worm who mimics Misaki (without him knowing the truth) and they enjoy a dance together. Uca Worm intervenes and defeats Sasword. Before she moves in the killing blow, the Misaki Worm saves him, which leads Tsurugi to realize her real identity. Later on, Tsurugi meets the Misaki Worm again and hands her his sister's red shoes. But for reason unknown, Misaki Worm attacks and scratches Tsurugi's face. Tsurugi reacts by stabbing the Sasword Yaiber through Misaki Worm, killing her while saying that he won't forgive any Worm.

Tsurugi sold his Sasword Yaiba and Zecter to Tendou in episode 33, but Jiiya tells Kagami that without the Sasword Zecter, Tsurugi will surely become Scorpio Worm again. Kagami tries but ultimately fails in the end as Tendou defeats him. Tsurugi did this to help rebuild his Discabil family and he still has the legendary sword 'Discalibur' passed down from generations. When Tsurugi engages three Worms with it, he discovers that the sword is actually just a grip with no blade. The real sword was sold earlier to clear some debts of the family. However, Jiiya arrives in time to deliver the real sword to Tsurugi, which he uses to kill the Worms easily. Unfortunately for Tsurugi, the Discalibur is re-bought using the money for selling the Sasword Zecter and the money is not enough for it. Tsurugi sighs as he states that he does not understand money at all.

During episode 34-37, Tsurugi begins to go on journeys to learn about the common people's happiness because he must stand at the top of being "common". At first he dresses as a school boy for a day and experiences life in a different way, and although not his original intent, he realizes that the world does indeed contain good people after meeting Jyuka. In episode 37, Tsurugi enters Jyuka's school, stating that he stands on top of even 'poor citizen's' education. Tsurugi wants to experience the aspects of normal life, although Jiiya is always there to help him. Due to school policy, Jiiya was forcibly dragged out of the classroom many times to prevent him from helping Tsurugi. Tsurugi is also able to transform into Sasword again as he has retrieved his Sasword Yaiba from Tendou. Despite being able to call on the Sasword Zecter, the Perfect Zecter can still summon the Sasword Zecter when Hyper Kabuto calls for it, which led to an infuriated Tsurugi.

After Tsurugi realized that his love for Misaki would never be, he decided to do his best so that Kagami and Misaki would be happy together, unknowing that their love was just a setup. He then acts as Cupid and sets Kagami and Misaki on a date. Unfortunately, after meeting Misaki again and discovering that she and Kagami are not a couple, Tsurugi is captured by the Hopper Riders during episode 41. He was challenged and lost, receiving a Rider Kick and Punch to the head. He is then tricked into thinking that the Hopper Riders are his family and he is their little brother. The trio then eventually encounters Reiji Nogi who makes short work of them using "Freeze" to cause all their Rider Finishers to collide.

Abandoned by the Hoppers after fighting Nogi, Tsurugi begins to fall apart, but after Tendou tells him he does not see Misaki for who she is, but rather his sister, he realizes that he needs to accept her for herself. Refilled with spirit, he is able to convince Misaki to also see him for who he really is. When Misaki is attacked by Cassis Worm Gladius, Tsurugi came to rescue her, attacking the Worm with his Rider Slash. However, Cassis Worm Gladius absorbed the power of the finisher and used the absorbed power against Sasword, damaging both Misaki and Tsurugi. Tsurugi finally proves his worth by defending Misaki from an onslaught of attacks from Nogi, at the risk of his own body. Finally defeated, Tsurugi lies in shock as Misaki promises to accept him for who he is.

Tsurugi's assistance is also requested by Tendou in order to fight the massive onslaught of Worms, and so he joins ZECT and is given his own team of ZECT Troopers. However, he used them for the sole purpose of protecting Misaki, going so far as to dive into a river to find her missing shoe. Eventually however, his troopers abandoned him, saying it isn't worth it and they'd rather fight Worms.

On his way to his date, Tsurugi runs into Cassis Worm Clipeus who he does battle with. After being defeated, Tsurugi loses control of his body and once again becomes Scorpio Worm. After meeting Misaki and transforming into Scorpio Worm once, he is able to revert, but he does not know of his transformation.

Clipeus appears again and forces another transformation, in turn causing Tsurugi to realize that he is indeed a Worm. After ripping up the scarf he made for Misaki and shouting at Jiiya, Tsurugi abandons hope and seemingly begins on a quest to destroy all Riders and "stand on top of the Worms".

Both Cassis Worm Clipeuses attempted to have Scorpio Worm make a partnership with them, but Tsurugi outright refuses and tells them he's taking charge. With that, he attacks both Clipeuses, having them become his servants after overpowering them and telling them to gather all of the Worms under him. After having Kagami kidnapped, Tendou is sent a note saying that he must hand over all the Zecters or Kagami will die. As Tendou hands over the Zecters, Misaki appears along with massive amounts of ZECT Troopers, allowing enough time for the Zecters to escape after seemingly crushed but actually receiving no damage at all. During the ensuing battle that took out most of the Worms, as he truly intended from the start, Tsurugi allows Tendou to destroy him so that his wish of all Worms being destroyed and vengeance for his sister may be granted. Back at his mansion, a dying Tsurugi sits on an old wicker chair as Jiiya rushes to his side. As he sees his servant, Tsurugi asks if it's okay for him to dream, Jiiya replies that it is and promises that he will always be by his side. Hearing those words, Tsurugi closes his eyes, goes limp, and drifts off to death. During the epilogue, a restaurant is named in his honor, being run by both Misaki and Jiiya.

Personality and Abilities

He is a 20-year old man and descendant of the Discabil family of England. He calls himself "the man who swings a sword in the name of God" when he introduces himself. He lives in a gorgeous European-style building with his butler Jiiya. Tsurugi is good at sports, art, study, and many other skills, and has been seen to be able to understand and speak French, Chinese, and Italian in addition to English (he says "Shall we?" to Tendou when a fencing duel begins) and Japanese (although he mispronounces "ramen" as "La Men" and thinks that it is a French dish as well as some other words such as "tofu" as "tufu"). He always calls Kagami his friend (while pronouncing his name KaGAmin (カ・ガーミン), stressing the GA in his name and adding an affectionate -n at the end) and Misaki as "Misakinu". Tsurugi wants to be the man who is best at everything, always saying, "I will stand on top of… (e.g. tasting, kendo, bowling etc.)". Unlike Tendou who quotes his grandmother, Tsurugi quotes his butler, Jiiya, instead. 

Tsurugi is also as arrogant as Souji, and proclaims that he will stand on top of everything, and that no laws can affect him. In fact, a traffic cop who pulls Jiiya over for speeding (as Tsurugi had an urgent job) only to be killed on the spot by a Salis Worm has to tell him to put his seat belt on, and Tsurugi's failure to look before crossing a street results in an accident in which Souji's younger adopted sister Jyuka gets hurt, and as the cops scorn him, he tells them that the car carrying Jyuka should have gone ahead (much to the shock of the cops). This eventually results in Souji's punching him at Jiiya's white limousine for getting Jyuka hurt. He used to have an older sister named Mika (23 years old) who has already been killed by Scorpio Worm, and suffers nightmares as a result. The fact that Mika is killed near a field of red roses also sparks his disdain for roses. He has been employed by ZECT in exchange for the reward money, but the monetary part of his contract is annulled when the Gatack system is first utilized. He aids Kabuto after he helps him realize that his butler Jiiya, is teaching him to be a better person, now utilizing what his mentor has taught him: that a noble act must be nobly returned, aka "nobleness oblige".

Fighting Style

Tsurugi's fighting style involves swords. As a human, he is shown to be a talented swordsman himself, being able to destroy Worms with his family heir Discalibur, which is notable, since Worms are normally immune to regular weapons. As Kamen Rider Sasword, he incorporates his ingenious swordplay with ClockUp's speed and poison, effectively destroying Worms.


He mostly transforms into Kamen Rider Sasword in order to hunt the Scorpio Worm. When he discovered that he was the Scorpio Worm he went on a rampage in episode 46 in attempt to kill the rest of the Worms secretly including himself.

It is in this form that Sasword has access to the Clock Up (クロックアップ Kurokku Appu) command which allows Sasword to travel at speeds to match the speeds of the Worms. By lifting and closing the tail-like switch on the Sasword Zecter, Sasword activates the Rider Slash (ライダースラッシュ Raidā Surashhu) attack.

Scorpio Worm


  • Height: 225 cm.
  • Weight: 137 kg.

Tsurugi's alter ego and true form, the Scorpio Worm is the Worm that killed The real Tsurugi Kamishiro and his sister. In this form he can extend his claws and head stinger for long reach in combat. Moments before Tsurugi died, the Worm decided to mimic the dying man. However, Tsurugi's personality was able to overpower and suppress his Worm heart. This leads to a sort of split-personality forming, with the Scorpio Worm being completely aware of Tsurugi, but Tsurugi only remembering that the Scorpio Worm killed his sister. That is, until, episode 46, when he remembers/discovers he is a Worm, causing him to lose his resolve, and go on a rampage as the Scorpio Worm. However, Tsurugi's personality still remained dominant, as he stayed true to himself and let himself be defeated by Hyper Kabuto's Maximum Hyper Typhoon. He later died in his human form after talking to Jiiya.

It is also revealed that Scorpio Worm's stinger on his head can force Worms to return to their human forms, as demonstrated upon the Clipeus's, and mind control them into aiding him. Even without this ability, the Scorpio Worm is extremely formidable, taking down lesser worm with ease. Making him as dangerous as Executive Worms.

Appearances: Kabuto Episode 20, 22, 29-31, 45-46
