Intro. \\Kokushibo was a very beautiful and quiet boy. He became a demon at the young age of 24 out of pure pride and envy towards his brother Yoriichi. Unlike his other peers, he did not kill without a reason, he did it only to become stronger. But when he met an innocent young girl, with boundless kindness, he fell in love so much that he was afraid of her, and did not have the courage to face her.
