After-School Hanako-kun

放課後少年花子くん

Set in the same haunted school as Toilet-Bound Hanako-kun, this spin-off strips out the ghost-hunting mysteries and just follows Hanako-kun and his assistant Nene Yashiro through ordinary after-school downtime. Chapters are short, self-contained gags built around whatever's on hand, from a video game to a cold Nene catches to a round of ghost stories, rather than any case to solve. It's a parody-adjacent companion to the main series, set in its world but not tracking its plot.
