Ayano Aishi messed up, somethign that didn’t happen often. She was a quiet girl, a highly intelligent sociopath who was also a Yandere. Taro Yamada was the senpai she was willing to kill for.
Taro had been showing more interest in the Martial Arts club, and that worried Ayano because what if he hung out with the girls of the club and fell in love and she lost him forever?? The solution she came up with was killing the president of the martial arts club, Budo Masuta so theh club would disband and Taro could not join. Easy. Budo was probably the most popular and attractive guy in Akademi High School, he was respected, liked, and feared too because of his extensive knowledge in martial arts- he was black belt and the current president!
Ayano gained his and the club’s trust, waited until his guard was down and killed him. But the rest of the students didn’t know that, all they knew was that BUDO MASUTA died.
Shortly after his death there was a ceremony held for him, all the students and faculty members gathered around the gym whilst the guidance counselor Genka Kunahito and the headmaster Kocho Shuyona gave a few words. The atmosphere was dense and grim, because no one held grudge against Budo- he had never been cruel with anyone, he was a strong advocate against bullying, he was always willing to help, why would anyone in their right mind do that to him?
