Background / History

Izayoi was born with the Third Perpetual Motion Engine within him. His biological parents were killed because of their research into it. Before their deaths, Canary abducted Izayoi from Little Garden and became his adoptive mother. After Canary died, her spiritual status failed to return to Little Garden and instead entered Izayoi's body, making him one of the strongest Original Candidates. 12

He was summoned to Little Garden alongside Hisato Asuka and Kasukabe Yō. Even with his overwhelming power, he considers himself below the world's true highest-tier beings and avoids directly confronting a former top Two-digit organizer who could recover her full power. 11

After joining the chat group, Izayoi travels between worlds, accepts missions, spars with other members, and increasingly acts as a protector and instructor. He trains the Hokages in physical conditioning, endurance, and self-reliance because he believes he cannot safeguard their world alone. 280 281

Personality

His confidence can become arrogance or overconfidence, particularly during his extended series of solitary battles. However, he adapts quickly after setbacks, using terrain, weapons, pills, and newly acquired abilities to overcome stronger opponents. 320 322 375 392

Despite his violent combat style, Izayoi is protective of people he considers friends. He refuses to doubt powerful humans who are his friends and trains others so they can defend themselves rather than depend on him. 280 281 He can also acknowledge when he has acted thoughtlessly, as shown when he apologizes to Kaname Madoka for focusing on his own desire for a fight. 215
