He enjoys video games. Though he puts up a happy front, he is depressed about his mother's death and blames himself. He claims to think about killing himself everyday. He is also a skilled runner and is the fastest runner in his class.
In the beginning of the story, Kakeru is introduced as a new student from Tokyo, who ends up sitting next to Naho in class. After the short school days ends, Kakeru is invited by Azu to her family's bakery for some buns. He initially declines but is convinced by Suwa to go.

The next day, is absent from school and stays absent for two weeks, attending the funeral and mourning the loss of his mother. While that happens, Naho in the story receives a letter which tells her to look after him. It tells her everything that happens and what she regrets not doing. It then tells her that Kakeru dies in an "accident" and that she believes she could have saved him. Naho struggles with doing the things her future self tells her she should have done because of her shy personality. He develops and confesses his feelings to Naho she says she has the same feelings but both never claimed they started dating so they love each other but aren't a couple yet.
Like his main timeline counterpart, he attempts suicide by getting run over by a truck, but this time he avoids it at the last minute because he became afraid to die.
