Izumi is the head of the Nase family and a powerful Spirit World Warrior. She's the older sister to both Hiroomi and Mitsuki, and she carries herself with real elegance—the kind you'd expect from someone representing a major family like hers. That said, she's refreshingly direct with people, never one to dance around things, and she manages to stay genuinely kind while doing it.
Around most people she comes across as pretty normal and composed. But fans often note the dramatic shift when she's around her younger sister Mitsuki—that's when her darker, more mischievous side comes out. It's one of her most entertaining character traits, honestly.
