Shione Sudo

Оригінальне ім’я: 須藤汐音

Shione is the vice-president of the student council, and Maya's younger sister. She often has a very extravagant hairstyle, which changes everyday, that even her own brother calls "complicated". Everyone became so used to her wacky hairstyles that they could not recognize her when she had her hair down, though Maya was overjoyed to realize that he had such a cute little sister.
