Drama halp pl0x :>

I'm trying to find the name of a Japanese drama after only watching a random episode of it, its pretty funny.

It involves some girl and an older guy that set up this fortune telling thing, well the girl dresses up like a fortune teller while the guy just does the background work.

Anyways, they investigate like the supernatural or supposedly supernatural events, and then as events unfold, near the end when they know the game, the girl dresses up in her costume and whips out her red fan and appears before the culprit behind the events to say hahaha I've caught you! etc.

the episode I was watching was of an english teacher being bullied or something which caused the security guard who happens to like her to make scary stuff to scare away the bullies.

ding ding ding and the catchphrase i can remember is "thats it!"

so.... any takers?

Sorry I dont really know the names of the actors in this one
