Reika Sata

Reika is Kyoya's older sister — a strikingly beautiful yet far more intimidating presence than her younger brother. Living in Kobe, she makes rare but unforgettable appearances, effortlessly dominating Kyoya with her overwhelming aura. Infamously, she once cut up his clothes, leaving him with a lasting psychological scar. Blunt and unapologetically sharp-tongued, she initially viewed Erika's relationship with Kyoya with deep suspicion and put her through a series of tests. Over time, however, Reika came to genuinely acknowledge and appreciate the positive influence Erika had brought into her brother's life.
