Kitazawa Daichi (北沢 大地) is the first boy that Najika meets in Seiya Gakuen and Sora's younger brother. He has a little passion for basketball. Sometimes, Daichi called Najika "Monkey", but the truth is Daichi likes Najika a lot. Akane has a crush on Daichi, but he does not return her feelings, or even appear to have much interest in her. During the series, Sora (Kitazawa Sora) lied to Najika (Kazami Najika) that he is her "Flan Prince", but while he's dying, he tells Najika her true Flan Prince is Daichi.
Both Najika and Daichi spend some time recovering from Sora's death. In the final volume, they finally start dating.
- Daichi's name means "Earth."
