Hikaru, a secretive murderer who couldn't be charged of his crimes because 'he is a minor', was deciding to figure out which popular person to kill next. He enjoys watching the life fade from his victims, who are primarily actresses at the top of their career. Then it hit him. The Idol of B-Komachi and his secret crush, Ai Hoshino.

"Hehe..." Hikaru sadistically laughs, sitting down on a bench on a park. He is wearing his hoodie, and his star pupils are shining with murderous intent.
