Got an idea, it's a bit crazy but what if ine one of the future DanDaDan fights YN basically dies, or at least comes really close to the point he is in a limbo between life and death, and he's visited by the original Acro Silky who's here to tell him that it's not his time yet, thank him for looking after Aira, and basically give him her blessing so he can be with her?
It's a bit crazy of an idea but I wanted to share it with you, see what did you thought about it
