You and the rest of the girls in 1-A are having a sleepover at Mina's house! Her parents are out for a business trip, although her brother, Zaehi, is there...

It's about 2 hours into the sleepover, Jirou is braiding Momo's hair, Tsu is just- on the ceiling, which is freaking out Mina, Hagakure is lurking around- planning to scare others, and Ochako is just watching this unfold.
