Kazuya Aoike

As a childhood friend of Tsukushi, this character joins Eitoku following his family's acquisition of wealth through real estate. He faces subtle social friction among his peers who perceive his newfound money differently than their established wealth. While deeply devoted and romantically interested in Tsukushi, his feelings are somewhat unexpressed and he is oblivious to romantic cues. Tsukushi experiences concern for his well-being, especially regarding Domyoji's apparent interest in him, though he remains absent from the main narrative.
