No personal arc oi personal growth for Miyuki. She's a several centuries old entity who has tried various paths and roads during her life. She's now reached the point where she's, essentially, that old granny down the street who's set in her ways and values, and ain't gonna change no matter what. Can't teach old dogs to sit and all that.

So if any of you were hoping for her to become more tolerable or amiable through the process of experiences and self-improvement.

Well... Nah, that shit ain't happenin', son~
