Hitomi

She is a first-year student in the same class as Natsuki. She has an interest in Natsuki and believes she can read him by looking at his eyes.

[Spoiler] When Natsuki forgot his lunch, she lent him money to buy a hot dog. When Natsuki forgot his umbrella, she offered a pink one with bunnies to him to use. She mistakenly interpreted Natsuki's love-struck look at Haruka to be directed at herself and thinks Natsuki has feelings for her. [/Spoiler]
