Isnt this like. Canon atp😭 i dont remember well but doesnt rika say she's the witch bernkastel i believe it was in a special higu episode??personally i think rika is bernkastel in the way that like. Bernkastel was born from rika's suffering(the hell bernkastel talks about could very well be rika's timeloops). Like how featherine is for hachijo ikuko, i think bernkastel is for rika, they're the same but on different planes of existence? Idk how much sense that makes😭😭
