|Himeko, Bossun, Switch, Himeko's Mother|
With the end-of-term tests fast approaching, Himeko panics at the prospect of getting marks all in the red. She convinces the rest of the Sket Dan to hold a study session, and her house is chosen for it. Unfortunately, things get off to a rocky start and only continue to go downhill as Bossun and Switch start slacking off instead of helping Himeko study. When Himeko's Mother discovers this, it is revealed that the "demon" nickname runs in the family: known as the "Oniyome" (demon bride), she will force the trio to study whether they like it or not.
