First Appearance

Reiteki Tsukishima is a Fullbringer and a member of American Branch of Xcution. He is Shūkurō Tsukishima twin brother as such he has the same ability.


Reiteki Tsukishima looks exactly like his brother, Shūkurō Tsukishima minus the scar and black hair. He is a tall young man with shoulder-length wavy brown hair, and brown eyes. He wears a long-sleeved collared shirt with suspenders and dark pants.


Just like his brother he is cold and collected in most things he does, normally appearing calm and even carefree. Even when overwhelmed and injured in battle, he is able to maintain his composed nature. Taking advantage of this unemotional nature, he is very cautious in battle, never acting without purpose or a plan.

He is sociopathic and amoral in nature, completely uncaring about the emotional torment that those indirectly affected by his Fullbring go through, even enjoying it as he mocks their pain. He also appears sadistic, purposely pushing the victims' trauma until they suffer mental breakdowns from the fake memories starting to conflict with their real ones.


When he was a young boy he was abandoned with his brother he gave his brother his scar and left to find his own way in the world. Eventually he was adopted into a kind family; his adoption was due to his ability to insert his presence into anyone he cuts. He grew up experimenting with his ability to make it more effective.

A year later he discovered that his brother was killed by a Shinigami; Tom invited him to join Xcution to take revenge against them.

Powers & Abilities

Expert Swordsmanship Specialist: He is a fine combatant able to make fast strikes. He is able to fight on par with a lieutenant-level Shinigami.

Enhanced Speed: Tsukishima has remarkable speed; his speed is far above that of a normal Human. Tsukishima is fast enough to strike his target before they can even react.

Enhanced Endurance: Tsukishima has shown a high tolerance for pain. Even after his arm got badly, he only showed moderate pain while staying calm.

Spiritual Awareness: Tsukishima has enough spiritual power to be able to see Shinigami.


Book of the End (ブック • オブ • ジ • エンド, Bukku obu ji Endo): Tsukishima's Fullbring manifests itself in his bookmark, which he can transform into a katana that has a bookmark-shaped tsuba. He remarks that his Book of the End is a sword with high attack capability that can literally cut through anything.

Book of the End is capable of two types of cut: one which can injure or kill an opponent and one which can insert Tsukishima into the target's past. he can combine the two types of cut.

  • Insert Presence: Book of End splits the past. It is possible because Book of End doesn't manipulate time and memories, but it rather has the power to insert "Tsukishima's very presence" into a person's past, upon cutting them. In connection to this Tsukishima gains knowledge of the memories that he has inserted himself into. To those affected by this power, it doesn't matter whether they trust him or not. To them, Tsukishima was always a part of their past. From somewhere in their lives, as family, a friend or lover, he is deeply entrenched into their personal lives even to the point of usurping other's roles in history. If Tsukishima cuts the same person twice, they will return to normal. When Tsukishima uses this ability, his victims do not experience any physical injury, despite feeling the sword cutting through them. Additionally, if the victim begins to realize inconsistencies with Tsukishima's presence in their past, and what has actually happened, they begin to suffer mental damage. He is also able to insert his presence into inanimate objects. By cutting the ground, he can falsify its history to alter its structure and set traps as if it was done long ago. By cutting through a person's attack or weapon, he is able to gain knowledge of all the person's techniques, saying that the knowledge becomes like seeing them so many times to the point "it's downright boring". However, if Tsukishima dies, the edited past will revert to the original state.


  • Not wanting to revive the original Tsukishima, I decided make it so that the original had a twin brother with the same ability.
