Misaki is Ikuto's little sister. Although it was not explored as much, in the letter Misaki sends to Ikuto, it can be assumed that she is very talkative. She has a bad sense of direction as she needed guidance from Ikuto to always go home. She loves fortune telling. She is introduced when Suzu and the others saw a picture of her with Ikuto and mistook her for his lover.
