I want to be an immortal or a super being living away from MC, demon lord and whatever chaos and harems taking place in the world, but I will be the kind of character that can end the world at any time I want and no one or anything can stop me, kind of like Zeno from Dragonball super but not a god
Fourth wall breaking support character/comic relief. I guess spirit pet would probably be a good fit.
The tentacles thing would be for me only if the girls consented first and they were at least 16 and look it!
Don't mind me, just a random tentacle playing consesual bdsm with some adult humanoid species here. That sometimes dressed as the holy-father protagonist. Much fun.
