Oiwa
Oiwa runs Senboukyou, a hot springs bathhouse that caters to a pretty unique clientele—basically, lingering spirits who need help moving on to the afterlife. She handles the day-to-day operations alongside Rei, a spirit who works there. The two make a solid team managing the place.
She's got a friendship with Otose that goes back a ways.
