Oh what an interesting au and cool video you made I hope to see more of this au in the future also seeing sans as luffy im curious what his gear five would look like?.
in that case Because of how many anime character's there are. And how many Undertale au's there are, I can't help but think there would perhaps be an Undertale multiverse in the style of this au and in such a multiverse one of the only au's I think could work for a rimuru equivalent is alphatale
