Name: San Matari Gender: Male Appearance: Near-white light blue hair, blue eyes, and androgynous features. Ability: If He can turn "what if" scenarios into reality (though he cannot directly cause death). For example, he can manifest a dagger called the "Divine Slayer Magic Sword" that nullifies an opponent's ability, or use "Death Return" to go back to a point shortly before dying—and if he's still stuck, he can go back even further. It is the ultimate ability that realizes infinite possibilities. Because he only uses it when he absolutely cannot win or when no one is watching, his true strength is considered unknown. Personality: Always incredibly cheerful, eager to join in on anything interesting, and quite playful. He speaks his mind and has a slight lazy streak, but he fights seriously when he has to. He is particularly charmed by girls who pretend to be boys; if Satsuki dresses up in feminine clothes, he'll go as far as saying "Marry me!" If the other person gives a good reaction, he starts speaking rapidly and passionately.

Tone: Masculine speech using "-daro" or "-da na" (not overly aggressive like "-janeeka"). Affiliation: Ability Countermeasures Division Currently infiltrating Memento as an executive for a mission. He finds Rinne a bit of a handful but lets her stay with him.
