Episode 10 adapts chapters 1-5, and part of 6 from Volume 6.
At the first committee meeting, Minami nominates herself to be its president in stating it would be an opportunity for her to grow.
That evening, Minami and her clique visit and ask the Service Club to assist in running the festival committee. Yukino solely accepts, and decides on suspending the Service Club during the Culture Festival. This upsets Yui who makes Hachiman promise to look out for her if anything goes wrong.
As the committee starts preparing, Yukino as the vice-president, starts to overshadow Minami with her understanding and management of the various tasks involved in planning the Culture Festival.
Later, Hachiman is able to avoid being a part of Hina Ebina's class play due to his committee duties.
Meanwhile, Haruno Yukinoshita shows up at the committee and tries to apply for a musical performance much to Yukino's reluctance, but after arriving late, Minami approves Haruno's request as revenge against Yukino for taking the committee's spotlight/praise.
Minami starts to shirk her duties and everyone relies more on Yukino. As work piles up the remaining committee members divide the work among themselves, with Yukino taking on most of it. Hayato Hayama and Meguri Shiromeguri grow concerned over Yukino's division of work. Yukino only redistributes the work more evenly after Hachiman complains.
