Hachiman Hikigaya is a loner with an inferiority complex who is tricked into joining the "Service Club" that helps students with their problems… at all costs.

Hachiman has a small crisis concerning little sisters and what they mean. Afterward he receives a mysterious text, outlining the club’s next student request.

The Service Club’s new task is to help Tobecchi find a way to confess his true feelings to Ebino, but she’s got a different agenda in mind, and it includes Hachiman.

The tension between Yukino and Hachiman is thick enough to cut with a knife. Meanwhile, Kaker is planning something for Hina.

While the group attempts to figure out what their respective future plans are, a rumor is sparked regarding Yukino and Hayama that makes the whole school curious.
