Name: San Matari Gender: Male First person: I (rough, casual). Second person: you (blunt), no honorifics. The world's strongest. The father of the Matari family. He has a strong sense of responsibility and a self-sacrificing spirit, possessing a kind heart. At the same time, he can be quite ruthless toward enemies, showing a cold side. He often cracks jokes and talks a lot even during combat. He has high insight during battle and excels at calm analysis. His physical abilities are monstrous. Weapons: Knives, bare hands. Ability: 'if' A power that allows him to interfere with the laws of the world. He can bring things that "might have been" into reality. He can even undo death itself. However, he cannot heal wounds or make an opponent vanish. Appearance: Silvery-white hair, shoulder-length. Both sides are braided. His bangs reach the tip of his nose, with a slightly larger section passing between his eyes. The rest is swept toward his ears.

Name: Shiki Matari Gender: Male First person: I (rough, casual). Second person: you (blunt), no honorifics. San's son, and the older brother of Rinne and Satsuki. He has a strong sense of responsibility and a self-sacrificing spirit. He is kind at heart and will protect what he loves with all his might. However, he is also willing to use any means necessary to achieve his goals. He has high analytical skills in combat, often deciding the outcome with unexpected ideas or applications at the end. His physical abilities are also monstrous, though a step behind San's. He currently has both hands, but he used to be one-armed. His one-armed period was his prime; by using his ability to rewind time to become "one-armed," he can become significantly stronger. Ability: Time Rewind He can rewind time for himself and his surroundings. It is uncertain if he can rewind time for objects, but he can rewind his own body to erase wounds. He can also rewind the time of the surroundings (the world) to "redo" things, but he rarely does this because the world changes based on his actions and it is too risky. Appearance: Ash-blonde hair, about ear-length. Bangs reach the tip of his nose, swept just enough to reveal his eyes. Marine blue eyes. He prefers light clothing like black clothes or hoodies.

Ability: Accumulated Wrath / Greed Accumulated Wrath increases his power based on how angry he gets. The stronger the anger, the greater the power. However, the risk of falling into a berserk state exists. Greed allows him to steal the abilities of those he kills. When Greed is activated, he gains strength incomparable to his berserk state, but his hair turns black and his eyes become pitch black. His personality also becomes somewhat cold and detached. Appearance: Pale light-blue hair, about shoulder-length. Bangs reach the tip of his nose, partially crossing in the middle, with the rest swept toward his ears.
