, ユキノ

The head mistress of Firefly House, Yukino discovered Shichiroji injured inside a floating capsule along a river. She then offered him employment at the house. Despite having an almost romantic relationship with each other, they have not yet considered marriage. Through Kirara's guidance, Yukino taught her that it is acceptable to indulge in pleasure and relaxation after working hard, which was previously viewed as disrespectful to the struggles of their village.
