The younger brother of Sora Kitazawa who has a little passion for basketball. He is in Najika's class and is popular with the girls at Seika Academy, though not quite to the extent that Sora is.
Daichi's first encounter with Najika was when Najika fell on him from a tree in Seika Academy's school grounds. This caused Daichi to refer to Najika as "monkey", but underneath the teasing Daichi has affectionate feelings for Najika and, like Sora, made her feel accepted at her new school.
