Personality
Enigmatic
Rigidly Conservative
Harboring Inferiority
Tradition-Bound Authority
As the commanding patriarch of Tsukuyomi Shrine, Ruza is a figure shrouded in deliberate mystery—famously concealing his face behind a briefcase in public. Beneath his authoritative exterior lies a deep-seated sense of inadequacy toward his brilliantly talented sister, who also became his wife. His relentless insistence that his daughter Sozomi return to fulfill her role as the shrine's highest divine priestess sparks fierce conflict with both his children, cementing his role as the embodiment of familial obligation and institutional tradition.
