A Japanese boy with a wild look and an aggressive personality, not to mention something of a womanizer, he confronted Sasha soon after his appearance, revealing himself to be a powerful Qwaser, whose abilities initially surprised Sasha, as Taisuku apparently had his same powers, though he managed to use them better. He is indeed a Qwaser, but his element is neodymium, which allows him to control any kind of metal through magnetism, not by interacting to it at the molecular level. He is also very skilled in Buddhist incantations, as he is the sole heir of a family of sorcerers and shamans, and thus can create elaborate incantations or even Buddhist-related weapons. His explosive personality and his occasional foolishness harbor a dark secret however: as a child he was greatly traumatized when his mother was brutally raped in front of him, which led him to become mad with ideas of revenge and turn to a life of constant conflict, slowly drifting to senseless anger. His encounter with Mutsumi Sendou saved him, and the two became inseparable since then. Though initially antagonistic, Taisuku quickly became a valuable ally, though he was accused of raping Hana and had to fight Ekaterina, when Friederich Tanner pitted the two against each other. When angered, he fights with a murderous frenzy that makes him attack with blind fury, especially if it's Mutsumi who's in danger.
