A man in a stretchy mask with a tragic past. He was in love with a woman, but her mother didn't trust him and forced her daughter to marry an automaton instead. When that automaton killed her, he transformed into a Shirogane—and that's when Lucille saved him from contracting Zonapha syndrome.
Rather than fade away, he decided to do something about it. He gathered other survivors of the syndrome and turned them into a team: the Sirogane-Os. The roster includes Zed, Fatima, Rockenfield, Timbavati, Schwarzes Tor, and Malina (who goes by Mina). These aren't just survivors—they're unified by a shared goal of taking down automatons, driven by the losses they've all suffered.
His real motivation, though, is personal. Everything he built came from grief and the desire to change a system that destroyed the person he loved most.
