Affiliated with the magic performance group IAM, which secretly experiments on individuals with Incomprehensible Skill of Human beings (ISH) abilities, Hasudō takes a keen interest in Amane Todoroki. He perceives significant potential in her as an ISH user, unaware her power actually emanates from her non-corporeal twin sister, Lilianne. This leads him to mistakenly identify Amane as an "archetype," a rare or extinct category of ISH user supposedly capable of wielding multiple powers. His misconception fuels his actions and drives his surveillance of her.

Hasudō's ultimate objectives remain ambiguous. He directs prominent IAM magician Aya to test Amane's perceived abilities through escalating dangerous scenarios, including orchestrating a situation where Amane must rescue her friend Kozumi from a berserk artificially awakened ISH user. Positioned as an orchestrator of IAM's clandestine ISH operations, Hasudō reinforces his authority within the group by subduing Aya. His specific goals concerning Amane, the archetype concept, or IAM's broader agenda stay concealed within the documented narrative.
