Evil Spirits all over!?

What if Mai wasn't the only student at her school to get drafted into helping Naru and Lin solve the case of the old school house? Who is the person from Naru and Lin's past that she resembles so closely in personality? And how will this affect the team, not to mention the plot line...

AN: Yuki Onna @darkyukionna does have my permission to borrow and quote directly from this story, so if you notice similarities between my 'Ghost of a Chance' and her 'Ghost Hunt', don't freak out.
