Izumi
Izumi is Souta's second eldest sister and works as an author. She's basically a shut-in—spends most of her time locked in her room hammering away at work while completely neglecting her hygiene and living space. Not the tidiest person.
The thing is, she's really weak. Like, legitimately frail. She actually crawls around on all fours instead of walking because standing and moving normally just drains her energy too quickly. It's one of her most defining traits, honestly.
