Yay, Neuro anime! Finally!
So I guess the information on the series as of now is as follows:
Name: Majin Tantei Nougami Neuro
Genre: Detective, Supernatural
Animation Production: MADHOUSE (YESSS)
Voice actors: Koyasu Takehito, Kana Ueda, Yusa Koji, Saiga Mitsuki
Estimated Air Date: October 2007 (filling the Jump hole left by D.Gray-man anime ending)
Estimated Episode Count: a lot
(being a Shonen Jump series). I think it'll make it to at least 52 episodes, but maybe more if ratings are good enough.
Though I'm unsure what to think of about the lead voice..... this character doesn't seem like the type that Koyasu will fit in.
