Kirari Momobami
Kirari is Yumeko's older sister, though she's currently hospitalized after a mental breakdown. Yumeko's been footing the bill for her treatment, which isn't cheap. Before everything fell apart, Kirari was a significant person in Rei Batsubami's life—though the exact nature of that relationship gets complicated depending on who's telling the story.
