Eiji Kakihana

Eiji Kakihana is a 41-year-old janitor who shares a long-standing friendship with protagonist Hiroshi Kogawa and physician Gōriki. Desperate to escape his bachelor life, he fabricates an impressive salary and academic background on a dating app—only to find himself entangled in a scheme involving an idol and organized crime, ultimately ending up kidnapped. His guileless, trusting nature stands in sharp contrast to Kogawa's chronic suspicion, making him a pivotal figure who embodies the vanity and helplessness of ordinary people chasing impossible dreams.
