This is pure fanservice, and it knows exactly what it's doing. Hanako and Nene have actual chemistry when the stakes disappear, and watching them bicker over nothing hits different than solving mysteries in the main series. The animation gets genuinely creepy in moments that have nothing to do with horror, which sounds contradictory until you see it. You need to know the characters already or this will feel like walking into someone else's inside joke. Four episodes isn't enough, mostly because the silly premise works better than the drama-mystery balance the main series was chasing. This is a show built for people who would rather see Hanako annoyed about afternoon chores than possessed by ancient curses.

Hanako, one of Kamome Academy's Seven Mysteries, and his human assistant Nene Yashiro, a first-year high school student, usually spend their time resolving supernatural incidents and keeping the peace between people and spirits. But what do they do when they get a break? This four-episode short takes a lighter turn, following the duo as they goof off after school in antics that pull in Nene's schoolmates and the spirits that ordinary people cannot see. The result is a breezy supernatural comedy with a slice-of-life feel.
