Mio lives in an abandoned temple where she cares for a group of orphans—children who lost their families to the ongoing war. To keep them fed, she works nights serving both warring clans, walking a careful line between the two sides. It's a tough gig, but she's committed to it.
What really defines her is how she puts the kids first, even when the work drains her. She's determined to do right by them, and the orphans see her as their mother figure. There's a genuine warmth to how she handles the responsibility—she's kind and caring without making a big deal about the sacrifice involved.
She's also Hyakkimaru's love interest.
