An elementary school student and Yuyu's older twin brother. Toto, along with Yuyu, work under Asclepius to get amorphous fragments. Like his sister, he is calm and collected, even in dire situations. Furthermore, he speaks with little to no emotion. While in Pure Illusion, he uses a device that fires a barrage of missiles.

Toto, along with Yuyu, was created by Asclepius; thus making them the first two amorphous children.
