折口 美羽

The protagonist's younger twin sister. Because they are the same age, she usually calls her brother by his name, but when she wants to act spoiled, she calls him onii-chan. She cannot take care of her own life, and is always acting spoiled in front of her brother. Her attitude towards him is pretty straightforward: because he is her only blood-related relative, she regards her brother as the most important person in the world. Her feelings towards her brother extend the realm of normal siblings' relationship. While she is very popular with the boys, she has not the slightest bit of interest in them. She also resents the other girls, especially the ones of the childhood gang.
