Narumi Fujishima, a 16-year-old high school student, carries the weight of frequent relocations due to his father’s career, cultivating an introverted nature and a guarded approach to relationships. His self-imposed isolation, rooted in a fear of inevitable goodbyes, clashes with a quiet yearning to find purpose. A chance meeting with the NEET Detective Team—spurred by classmate Ayaka Shinozaki’s invitation to the gardening club—propels him into a world of investigations. His unorthodox methods, favoring personal ethics over detached protocol, gradually reshape the team’s dynamics.

Driven by an unwavering belief in human connection, Narumi repeatedly jeopardizes his safety to defend strangers, a trait that forges deep trust with those he aids. His bond with Ayaka becomes central to his emotional world, particularly after her suicide attempt leaves her comatose. Consumed by guilt and determination, he ingests the hallucinogen Angel Fix to unravel her motives, a choice that accelerates his growth while hardening his resolve to shield others. Ayaka’s eventual awakening, marred by amnesia, strains their fragile relationship, testing his resilience.

Though untrained, Narumi exhibits sharp technical prowess, dismantling malware and crafting websites with ease—skills that earn him the moniker “God Hand” from the Hirasaka Group. He outwits mahjong masters through strategic cunning and replicates intricate artwork from memory, proving indispensable to the detective team’s eclectic operations.

His arc traces a shift from hesitant bystander to proactive investigator, bridging gaps between the team’s eccentric members and external allies. A mutual respect blossoms with Yondaime, the Hirasaka leader, who increasingly defers to Narumi’s instincts during crises. Through relentless cases, he navigates a path between idealism and pragmatism, steadily embracing leadership while confronting the moral complexities of his choices.
