Following a successful Ayanagi Festival, Yuuta Hoshitani and the members of Team Ootori celebrate the start of the new year and their final semester as first-years at Ayanagi Academy. However, with Itsuki Ootori expelled from the Kao Council, Team Ootori no longer qualifies as a Star Team. Deprived of their privileges, they are also barred from participating in the upcoming graduation ceremony. Desperate to bring their mentor back, Hoshitani and the others devise a plan to persuade the Kao Council to allow Ootori to resume his former position.
