He is the owner of a store that deals with many magical items. He is very greedy and will often overprice his wares if he has the chance.

You say you got a ghost in your prefecture? In Japan that means you need to call Ghost Sweeper Mikami, the paranormal detective agency that's a little abnormal. Okay, make that a LOT abnormal, but they DO specialize in disposing of things that most people don't even believe exist. Run by the visually delicious and even more avaricious Reiko Mikami, and aided by the very perverted (but also very loyal) Tadao Yokoshima, they'll take any case that pays. And Tadao will do anything that might let him sneak a peek at Reiko's magnificent physique. How unfortunate for him that Reiko basically sees him as cannon-fodder, something that's quite useful when your day to day business involves exorcising oni, yurei, yokai and anything else you might find in The Illustrated Bag of One Hundred Random Ghosts.
