SSBU Murder Mystery

This is a murder mystery story that includes ALL of the characters in the roster, although some don't have lines. I am writing this based off what I know about the characters, which isn't much, but I'll work with it. Also, I've decided to go Byleth (F), Robin (M), and Corrin (F). Finally, in my story, canonically, the Miis are Colonel Sanders, Guy Fieri, and Doomslayer.
