this is a movie back in 2005 where Kamenashi from Kat-Tun is the lead together with Juri-chan(Miyuki). It's based on a detective manga, with Kamenashi starring as Kindaichi Hajime, the grandson of a famous detective long ago. Literally. xD

So, the story starts where both Hajime and Miyuki, both are childhood friends, went to this abandoned hotel , rumored to be haunted by vampires, and with a few other customers, they got involved in a murder case. And after having Miyuki being the prime suspect, Hajime had no choice but to try to solve the case.
This is just the beginning of the movie where two members of Kat-Tun had a cameo appearances i suppose...

and here we have Hajime, the NO.1 pervert in this movie, but then transforming into a smart detective. Or at least he was serious during the case solving, but then returned to his natural habit towards the end. xD
It's actually a pretty easy going movie, it's not scary at all. Especially having a member of Kat-Tun here, it's more of like an eye-candy. But his acting isn't bad.
