Hachiman Hikigaya is an apathetic high school student with narcissistic and semi-nihilistic tendencies. He firmly believes that joyful youth is nothing but a farce, and everyone who says otherwise is just lying to themselves. In a novel punishment for writing an essay mocking modern social relationships, Hachiman's teacher forces him to join the Volunteer Service Club, a club that aims to extend a helping hand to any student who seeks their support in achieving their goals. With the only other club member being the beautiful ice queen Yukino Yukinoshita, Hachiman finds himself on the front line of other people's problems—a place he never dreamed he would be. As Hachiman and Yukino use their wits to solve many students' problems, will Hachiman's rotten view of society prove to be a hindrance or a tool he can use to his advantage?

This season picks up immediately after the events of the first season, continuing the adventures of the Volunteer Service Club—the dispassionate Hachiman Hikigaya, the cheerful Yui Yuigahama, and the competitive Yukino Yukinoshita—as it dedicates itself to helping any student with issues that they may face. With the rift among his own group widening, Hachiman begins to realize that his knack for quickly getting to the root of other people's troubles is a double-edged sword: sometimes the best solution is not necessarily the most appropriate one.

The messy emotions of Hachiman, Yukino and Yui won't be easily expressed, and as the members of the Service Club band together to host a school prom, they will have to put their feelings into words and truly learn to understand each other at long last... if the Service Club can even stay afloat, that is!
