Misaki, the iron-fisted student council president, is discovered working in a maid café by the most popular guy in school and must find the price for his silence.

Misaki's secret becomes harder to keep when it's found out by the "Three Idiots" trio: Kurosaki, Shirokawa and Sarashina. What's more, the school festival is right around the corner, and Class 2-2 is showing signs of rebellion.

Maid Latte decides to host a Little Sister’s Day. Misaki has trouble acting the part, but after Honoka scolds Misaki for not taking it seriously, she turns her act around. She plays the part well-- until Takumi arrives to hassle her.

Maid Latte is visited by Aoi, a famous net idol who is also Satsuki’s niece. Aoi is excited to try the café’s uniform, much to Satsuki’s chagrin. Meanwhile, Takumi helps out in the café's kitchen. Aoi finds Takumi attractive but he ignores her.

Satsuki warns Misaki about a group of stalkers targeting cosplay cafés, but Misaki isn’t worried. On a night when Misaki is closing the café alone, she is caught by the stalkers. It falls to Takumi to rescue her.
