  Summary

  Basically right before round one, everybody is rescued by the straw hats and others before anyone dies. This is heavily inspired by that one fandoms react to sua gacha video that has all the previously listed characters. Creds to sunnocoster for the idea.

  Oh also for context, all non alnst characters watched the asnst universe in a gacha reaction. Luffy gives Sua his hat and promises that he and the others in the room with go save her.
