Sunnyside Daycare Classmates

In a distant future, Jin awakens with absolute amnesia, retaining no memory of his identity or origins. Though he finds himself battered, bruised, and bleeding, he discovers that he possesses formidable combat abilities. Unbothered by his lack of history, Jin simply moves forward, giving no thought to the secrets of his past. That indifference shatters when he is captured by a security firm known as Scanner. During his detention, he crosses paths with a group of eccentric men who make a startling claim: they are his former classmates from Sunnyside Daycare. This unexpected reunion plunges Jin into a bizarre and horrifying adventure as the hidden truths of his forgotten early years begin to surface.
