Daichi Kitazawa is Sora Kitazawa's younger brother and has a mild interest in basketball. He shares the same class as Najika at Seika Academy and, although popular among the girls, he isn't quite as admired as his brother Sora.
Daichi first met Najika when she accidentally fell on him from a tree on the school grounds, leading him to teasingly call her "monkey." Despite this playful banter, Daichi harbors affectionate feelings for Najika and, like Sora, helps her feel welcomed at her new school.
Over time, Daichi's feelings for Najika deepen, and by volume four, he realizes he has a crush on her. However, his feelings turn to jealousy when he overhears Najika telling Akane Kishida that she has feelings for Sora and plans to confess after her cooking competition ends.
Daichi struggles with understanding his emotions, needing Sora's help to realize his romantic feelings for Najicha. In a moment of jealousy, Daichi kisses Najika, but later tells her it meant nothing when confronted about it.
Akane has a crush on Daichi, but he doesn't reciprocate her feelings or show much interest in her, though he does express concern when he learns about her eating disorder. Daichi has a strained relationship with both his brother Sora and his father, viewing Sora as a "traitor" for accepting their parents' remarriage and feeling distant from his father, especially upon discovering his father's intentions regarding Najika.
Daichi is Najika Kazami's Flan Prince and had amnesia due to the trauma of causing his mother's death. His memories return after seeing a photo album of himself and Sora in Hokkaido. His name means "earth."
