What wiz are we talking about here. Anime character, or the one from the michael jackson wizard of oz remake set in an urban styling?probably anime becaue lich or whatever liches are undead which isn't fully dead as undead which literally means not dead. It's like a dead where you aren't dead but are also on a level dead. un-dead removed dead. living but also dead. Unlss liches work differently in anime then yeah legal isn't really a thing you should be asking as theoretically if a skeleton was living you'd be able to fuck it if it was capable of fucking which is isn't cause its just bones. Asking if it's legal to fuck a lich is like saying "is it legal to fuck skeletor?" Shouldn't even be a question.
This is FALSE and DISHONEST and you are a fucking incest fetishist gone rouge.
Is he just standing there or is his car in your garage? throw salt at him or some shit like that if it's just him. might be a demon pretending to be batman.
