Yamazu ni Koishite, Koroshiya-san!

A love comedy about a yandere assassin and a totally innocent girl who avoids danger! The main character, Sumika, has always been unable to read the mood of a situation, and people have always kept their distance from her. One day, when she handed a handkerchief to someone she was fighting with on the street, the next day that person transferred to her school...? "I quit being an assassin for you. Please fall in love with me." Her first confession was a terrifying signal that her life was being targeted by an assassin organization.
