Kazuki Yuiga

Kazuki Yuiga is the younger brother of protagonist Nariyuki in 'We Never Learn,' and shares a twin bond with his sister Hazuki. Bright and full of energy, Kazuki also possesses a surprisingly sharp intuition, allowing him to pick up on the subtle romantic tension between his older brother and the girls around him—often teasing Nariyuki about it with playful wit. Despite the family's modest financial circumstances, Kazuki remains deeply devoted to his loved ones, willingly pitching in with household chores and embodying the spirit of a cheerful yet remarkably mature young boy.
