Shichika Yasuri (鑢 七花, Yasuri Shichika) is the male protagonist of the series Katanagatari and the seventh head of the Kyotōryū school of Japanese sword martial arts.


Shichika knows nothing of the outside world, leaving him clueless to how embarrassing, annoying, or obvious his actions can be. In other words, he is often confused by simple customs and even has trouble telling people apart. He was raised as a weapon, and as such, is bad at expressing emotion, though he does regard Togame as his wielder. He states that he is in love with her, following her orders even when finding them to be a hassle. As he meets more people, he becomes more human and feels remorse for his previous actions.

When he was a child, he was innocent.


Shichika has a seven-pointed leaf motif throughout his design. His hair is shaped as a leaf and leaves appear on his thick, red ribbon belt, hands, ponytail, and hakama. As Shichika is not familiar with society, he walks around only half-clothed. He considers being fully clothed a hassle as it impairs his movement while fighting.

Formally, he wore a plain leaf-shaped vest and plain pants with a thick, black ribbon belt.

At the end of the series, he wears Togame's one-sleeved kimono (now dyed red) as a belt, as well as tying a lock of her hair to it.



Shichika at a younger age

Due to his father's exile, Shichika was raised on an isolated island in Tamba. He was second-born but chosen over his sister, Nanami Yasuri, to inherit the Kyotoryu fighting style. He feels protective of his sister and killed his father in order to protect her. Shichika does not seem aware of Nanami's true skill.


Volume OneEdit

He is twenty-four when he is sought out and employed by Togame with a mission to find the twelve legendary Deviant Blades.

Volume TwoEdit

Shichika arrived in Kyoto (京) with Togame, where Shichika was soon viewed as a naked man by bystanders. To prevent suspicious purposes, Togame brought clothes for Shichika, but he strongly denied wearing anything for the upper body, saying that it is heavy and will get in the way. They ran into bandits along the way but Shichika quickly defeats them, however, Togame told him to spare them. Meanwhile, at Inaba (稲葉) Desert, they found the corpse of Shirasagi Maniwa, one of the 12 heads of Maniwa corps lying across the desert, they head to Gekoku Castle to obtain their second deviant blade, Zantō Namakura, which is wielded by Ginkaku Uneri, an expert swordsman. When Togame negotiating with him, Uneri said it was rude to talk to a swordsman across the door and requested her to enter the room, which was obviously a trap to lure him into his attack range. Shichika quickly reacts and save Togame from Uneri Zerosen's, Ianuki, a supreme sword technique, then retreat to strategist. Shichika admits that his Zerosen is so fast that he cannot see the blade at all.

During the second confrontation, Shichika thought of a counter for Uneri's Zerosen, and he creates a phantom illusion using Kyotōryū Nana no Kamai: Iris  (アイリス), allowing Uneri to miss, and then defeats him with Kyotōryū Ougi: Rakka Rouzeki (落花狼藉, Scattered Blossoms), thus getting their second deviant blade: Zantō Namakura.

After the battle, Shichika admires Uneri's pride deeply, as he thought his final line was really cool. Togame told him it wasn't a catchphrase, it was a dying message, and told him not to think too hard about it.

Volume ThreeEdit

Togame and Shichika departs to Izumo (出雲), where they encounter Meisai Tsuruga, the Sanzu (三途) Shrine Head. She is willing to give over Sentō Tsurugi if they accept some minor conditions, which is for Togame to identify the first blade of Sentō Tsurugi without the help of Shichika. If Togame succeeds, Meisai Tsuruga will fight Shichika one-on-one, if he wins, she will hand it over, if he loses, they will give her Kanna and Namakura. Shichika thought it wasn't fair, but Togame explains that she wants to avoid killing this time round. When Togame was out inspecting the blades, Shichika helped the shrine maiden with chores but does not feel Shikizaki's poison aura. Later, Meisai invited Shichika for a drink as ahanks for helping up the shrine maidens, she explains that the temple is like a refugee camp, they are victims that mental health was destroyed from long-termed abuse by men, she wants to use the poison of Shikizaki's poison as medicine. After hearing that, Shichika still promised to fight to his utmost ,without doubt, they both shared how much people they had sleain he also told her he slain his father. Meisai then asks what on earth do eshe fight for, to which he replied, "For Togame."

Later they realized they had been watched by one of the 12 heads by Maniwa corps, Kuizame Maniwa. Mesai Tsuruga then demonstrated Sentouryū on Maniwa Kuizame, killing him instantly. She then asks Shichika to take care of the corpse himself. Later he reunited with Togame, informing her that Maniwa corps attacked. Togame gave Mesai the blade that she assumes is the original since it has the oldest sheath, Mesai agreed with her thoughtlessly and commence duel the next day. During the duel, Shichika then realized the hunt for the original was just an excuse to bide time for Mesai to set-up Chikeikōka Sentō Meguri (地形効果・千刀巡り, Terrain Effect: Thousand Sword Circumference), he then escaped to a terrain that he knew she won't lay a trap, the place where Togame and him stayed. Despite that, Mesai still draws out the disposed sword from the ground, and Shichika then identifies that the sword is the original since it is the sword that chooses the master. Shichika then defeats her with Kyotōryū, obtaining the original third deviant blade. On the way back to Owari, Shichika then asks Togame that if he loses, will she had handed over Mesai Kanna and Namakura, and Togame replied that she never once thought he would lose. Shichika smiled upon hearing that.

Kyotōryū: As a practitioner of the legendary Kyotōryū fencing school, he does not use a literal sword when fighting. Instead of a sword, he uses his hands and legs as weapons; the Yasuri family has historically been unable to handle real swords.

Kyotōryū"Red Poppy" and "Daphne" hybrid striking technique - This technique allows Shichika to take all weight out of his enemy and his blows, making it possible to kill his opponent 272 times before it hit the ground, as seen in his fight with Uron.

Enhanced Strength: Due to his training since a very young age (likely since the day he could walk), even when not using Kyotoryu Shichika boasts of extreme strength surpassing that of ordinary humans, best illustrated in his fight against Zokuto Yoroi.

Extreme Speed: Shichika's base speed in battle also greatly exceeds common standards, since he can move so fast as to create afterimages, as shown in his fight against Zanto Namakura and Ento Jyuu.

Enhanced Durability: It is shown that Shichika was able to sustain multiple bullet wounds from Ento Jyuu and was still capable of defeating Emonzaemon Sōda, as well as destroying the last Deviant Blade.

Immense Reflexes: Shichika's reflexes are enhanced beyond the human limits. In shogunate's castle, he was capable of stopping Zantō Namakura's strike with his bare hands, simply blocking any of retainers' attacks easily, with an exception of Emonzaemon Sōda's Ento Jyuu.


  • Shichika Yasuri literally translates to "Seven Flower Rasp".  His father's name, Mutsue, partially translates to "branch", symbolically making him the product of the tree that is Kyotōryū.
