This episode takes place sometime after the second season, after the first years completed their Stagiaire assignments. The Polar Star dorm residents, along with the Aldini brothers, Ikumi, Kurokiba, and Hayama, take a trip to the hot springs inn where Megumi did her Stagiaire. After a business trip, Alice, Erina and Hisako decided to go to the hot springs for a break, too. Arriving at the Inn, Megumi and Isshiki showcased their table tennis finesse. With all of the Inn's cooks suffering accidents, the Polar Star gang and the others took over the kitchen for the arriving guests: Erina, Alice and Hisako; who are impressed by the finely crafted meal supposedly made by amateurs, not knowing it is made by Tootsuki students. Yukihira, intrigued by the legendary fish dubbed the 'River Master' in the nearby river, invite Kurokiba and Hayama to a fishing match, only to dragged along in the water and coming back empty-handed. Later in the night, Megumi met Erina in the hot springs bath, realising that the meal that she and the others cooked is for Erina.
