The arrival of Toono Zen as her substitute homeroom teacher is an extremely vexing proposition for Miko. There are an inordinate number of intense cat-demons constantly surrounding the guy, who doesn’t seem to notice. At least he doesn’t seem to remember her from the stray cat encounter, while Hana can’t quite place the guy and Miko encourages her to believe she’s mistaking him for someone else.
Still, Zen’s demon hangers-on creep out Miko to the point she retreats to the bathroom, only to encounter another gigantic ghoul who climbs out of the toilet in her stall. Miko uses the fact there’s no TP to retreat, only to find Yulia eating her lunch in the stall next door. Mind you, Miko is only alone because Hana went to buy bread to eat after she ate her regular lunch.
Miko is of the mind that no one should have to eat their lunch in a bathroom stall, so invites Yulia to join her and Hana outside. Yet when she spots their teacher once again walking down the halls, Miko’s eyes suddenly fill with tears, concerning both Hana and Yulia.
The bulk of the remainder of the episode consists of a test of courage in the form of a haunted house set up by the local donut concern; if customers can brave the house and get their card stamped, they’ll receive 20 free donuts. Hana is an incurable scaredy-cat, but Miko simply loves the opportunity to be able to react to scary things by screaming. The fact that she smiles as she screams is particularly disturbing to Yulia!
Miko ends up seeing a real ghoul among all of the haunted house monsters, but she’s still able to react because the ghoul can’t be sure who she’s reacting to: the genuine article, or the artifice of the haunted house. When all’s said and done the three friends end up going through the ringer but coming out of it closer than ever…not to mention 20 donuts richer!
