The season for the annual school festival that students look forward to has arrived. Rina, who is laid-back and a bit clumsy, was in charge of ordering costumes for the entire grade but somehow received obscenely revealing reverse bunny costumes instead. When she tried them on, her breasts and private parts were fully exposed! The costumes for other classes were all equally erotic, and she ended up having to help out at other stalls as well… Will this year's school festival be able to end without incident?!
