So FluffyBunnyPwn introduced me to this drama, and I have to say, I was a little skeptical about how good this drama was going to be. BUT, turns out that it was pretty damn good. It was exactly like Fluffy said it would be, "Your typical shounen anime turned into a legit shounen live action drama." It really felt like watching a live action anime. Too bad there isn't an anime for it though.
Kotaro Mochizuki is your typical wimpy main character. He gets caught sleeping in class and has to write a 30 page report about The Summer Campaign of the Siege of Osaka. On his way home he notices an odd building called Shinonome Library of History. He goes in and receives a book from the warring periods and notices that it's about a samurai with his exact name. Things start getting crazy from there and he gets possessed by the samurai from the book.
