A little while after Enjou Kanata entered high school, he began to hear a certain name frequently. Sakatoki Aya. Kanata had no idea who this person was. One day, a new student transfered to his class. Her name was Sakatoki Aya. She was really beautiful, but Enjou was greeted by this girl he had never met before with ‘long time no see.’ From there, he was followed by Sakatoki, who gradually solidified her presence around him. The horrifying, yet sweet, romantic comedy opens with the realization that a yandere is the strongest character in romantic comedies.
