9 parts Complete Ato is a puppet left without a master. Ato has brown eyes and hair. Big stars are clearly visible in the eyes
He used to help his master with various things, these are connections with experiments. This master's name was Yuto. Yuto's experiments were illegal in Inazuma, they were forbidden. He did experiments not only on puppets, but also on humans.
Ato could only have lived with his master for five years. In the last two years, Yuto began to go crazy, became obsessed with experiments. And he became a victim of his own experiments... There was a fire, his experiments were destroyed along with him except for one of his creation - Ato.
Ato himself did not know that he existed like other puppets, like Scaramouche once, now a Wanderer.
