Isshiki approaches the Service Club with and interesting proposition, but Yukino would like to handle this time-sensitive challenge on her own.

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!

Hachiman is determine to help bring the prom to life, but Yukino isn’t keen on accepting his help. Luckily Hachiman has a plan — one that uniquely involves the Service Club.

First step in Hachiman’s plan? Rally the troops! Together they’ll create a prom proposal so awful, the PTO will have no choice but to choose Yukino’s instead.

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

Now that the club has disbanded, they’ll continue to drift even further apart — but before they do, Yui has one final wish to make.

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