The stage this time is the UA dormitory just before season 5's Endeavor Internship arc! In the middle of winter, a hot and blustery cold battle is unfolding at Heights Alliance! Third-year Mirio Togata appears suddenly as the first-year students in Class A are bored during their ban from going outside. He brings with him the card game "Yuuei Heroes Battle," created by the support class. As each student picks cards and joins the fierce battle, there seems to be more to the game than meets the eye. At the end, who will emerge victorious?

After succeeding in their winter conflict against Taiju Shiba and his Black Dragons, the Tokyo Manji Gang absorbs their group's remaining members. Due to his heroic courage and indomitable spirit, Takemichi Hanagaki should have accomplished his goal of defeating the tragic fate awaiting his girlfriend, Hinata Tachibana. In reality, Takemichi's troubles are far from over. Although Takemichi's actions have exposed Tetta Kisaki's treachery, the conniving schemer has found power elsewhere: Tenjiku, a dangerous gang led by the enigmatic Izana Kurokawa. Izana sets his sights on Manjirou "Mikey" Sano, pursuing a vicious interest in the Tokyo Manji Gang's aloof leader. In the future, Takemichi discovers that the machinations of Izana and Kisaki led to Mikey's moral ruin—a downfall that directly results in Hinata's death. Unfortunately, a terrible loss robs Takemichi of his time-leaping ability, stranding him in the past with one final chance to rescue everyone he loves.
