Akashi has a split personality named Bokushi. Unlike Akashi, Bokushi is heartless and evil whereas Akashi is kind and caring. Bokushi always control Akashi's body and even if he want's to stop him (bokushi), he can't for he's weak. Until one day, Bokushi stops controlling his body that it last for a month. He thought Bokushi is really gone until he met Kuroko Tetsuya and fall in love with him. Unfortunately, Bokushi takes full control of his body and kill Kuroko. He takes full control over his body after but it's too late; his lover was on the floor soaked in his own blood right in front of his very own eyes.
