i wanna imagine Vash having a very soft spot for plants and likes gardening v much, he could be a flower shop owner too and he'd enjoy his day just tending to his flowers and talks about flowers to a customer......
the duality is no one would suspect a flower shop owner would be such a good gunslinger too
Another prompt I did with was Prank/Trick involving two animatronics I made call Dill/Mini and Arte. Arte is a little prankster, but they don't work out for him a lot of the time. Dill has split personality. Dill a happy go lucky flower and Mini, a more mischievous side who likes to torment. Thus why he turns dark.
