Itsuki Nishikawa

Itsuki is a 1st-year student in Seiran High and an information committee member. Up until the first year of grade school, she used to be Sawa's neighbour and they often played together. After she had to move, she met again with Sawa by chance when entering high school. But seeing that Sawa had forgotten everything, she held a grudge against her. She's an only child and has a dog as a pet.
