Koshitan no longer wants to be driven crazy by Nokotan and decides to spy on her to find her weakness. This leads her to the zoo, where she observes Nokotan at work.

It's finally summer in Hino, and that means one thing above all: a new look is in order! The students are wearing their short-sleeved school uniforms, and even Nokotan appears in a new, somewhat concerning state.

Nokotan wants to participate in the Deer Collection and needs Koshitan's help for it. Koshitan livestreams what daily life is like in the Deer Club. The owner of Café Swallow takes pride in his perfect service, but then Koshitan and Nokotan visit his establishment.
