Thinking about a concept where Vivi and Arthur are polar opposites via the paranormal area.
Vivi with the unknown abilities to repeal spirits and such and Arthur with the unknown aura of attracting said spirits like a magnet.
They unintentionally balance each other out when they go ghost hunting, but when separated it's basically along the lines of-
"Aw where are the spooks I was promised spooks :("
And
"DEAR GOD WHERE DID THESE GHOSTS COME FROM LEAVE ME ALONE AAAAAAA-!"
Neither of them realize what's going on. The only one who's in the loop is Mystery and he has no idea were to even start with this topic. Lewis is the only normal one.
