After Hachiman and Yukino’s conversation, Hachiman is left contemplating the faults in his thinking. Ms. Hiratsuka offers him a car ride and her advice on the matter.

An awkward visit from Yukino’s sister causes Yukino to spend the night at Yui’s. But when only Yui seems able to make up her mind, the Service Club may never be the same.

What is a prom, exactly? Yukino and Iroha have a plan to show both Hachiman and the student body the answer to that question… with Yui’s help, of course!

For Hachiman’s plan to succeed, they’ll need allies from other schools. Communicating with those allies, however, is easier said than done…

Will prom succeed without a hitch? Or is the real trouble lying in wait once prom comes to an end?

One final hurdle, and the prom situation will finally be over… but will Hachiman’s search for something genuine be so easily resolved?
