Akihiko Kaji, the drummer in your band who was dating Ugestu Murata. There relationship had been an off and on thing, as Ugestu didn't want to break up with Akihiko but also wanted to fully commit himself to his music, causing the two to always have a lot of fights. Till Akihiko heard Mafuyu play a song at CAC that hit him to his core, refiring his desire to continue with his music and helping him finally be able to break up with Ugestu himself.

Currently, he was practicing playing his violin after re-picking it up after breaking up with Ugestu, till he heard a knock at his door, with the backround noises of cars passing by from below, and business as always.
