@mirima I think eri lost her quirk when she cut her throne but I'm not sure

@Alya i dont think thats how it works bc the only way we've seen to loose a quirk is by afo, the quirk erasing thing and by having the body part the uses the quirk damaged and eris horn is just a store for her power so i think she just did that for it to be portable bc oviously she couldnt go to the battle
