I'm pretty sure I watched this special just for the cast! A few of my favorites are: Narimiya Hiroki, Yamada Ryosuke, Arioka Daiki, Kawaguchi Haruna, Haru, and Nichkhun... just to name a few! Narimiya Hiroki is superb at playing the "bad guy", and Yamada Ryosuke is great at being the comedian/funny guy and the detective (although I'm biased since before this I watched Tantei Gakuen Q) The story was a little creepy, so I'm glad I didn't watch this at night because I am a huge scaredy cat! But, the story was well written! I never once predicted the outcome, never once guessed the suspect, and the story moved at a great pace, I never felt lost through the special and understood pretty much everything. It was great to see how Yamada Ryosuke (aka Kindaichi Hajime) deduced the case and figured out the truth. Although, that could be biased too since I'm on a detective drama kick right now!
