Isami Oomiya

Isami Oomiya is the older sister of Shinobu, a tall and professionally poised fashion model who commands attention both on and off the runway. She showers her little sister and Alice with boundless affection, carrying herself with a calm, refined elegance in everyday life. Yet beneath that composed exterior lurks a sharp, teasing side that surfaces without warning, leaving those around her both flustered and amused. Ironically, despite her glamorous public image, Isami shares her sister's notorious inability to wake up in the morning—a surprisingly relatable quirk hidden behind her polished façade.
