I'm not sure what to call it so in lieu of bob, I'm calling it Guishenkai it is a spirit entity that has been passed down to Hihanako. Neither good nor bad, it just does what it wants and has no physical form. Still gotta find out what this entity wants, likes, dislikes, what caused it to be out of balance and etc.

Their name is Henhageshii. Yes there's two i's at the end. Their species is Guishenkai. Because apparently I'm into portmanteaus right now.
