Another girl who is connected to Yuichi's past is Mai Kawasumi who attends his high school as a third-year. She takes it upon herself to fight and defeat demons at night while the school is deserted.Translated quote: "I'm a demon hunter."</ref> Due to this, she is constantly blamed for accidents because she never denies them, being too sincere to say anything and knowing that no one will believe that there are demons in the school. Yuichi coincidentally meets a fifth girl named Shiori Misaka who he gets to know along with the other four heroines in the story. She has suffered from an unexplained affliction since birth which makes her weak to the point of missing school because of it. Yuichi starts to talk with her more after noticing her in the school courtyard one day. It turns out that Shiori stands outside on the school grounds nearly every day because she wants to meet someone dear to her.
