Great!..But Too many Fillers..(Spoilers Perhaps)
Come on you gotta agree. 1-9 The Storyline is great! i loved it then came the OVAs revealing Maya Natsume's past ..then it came back to the main storyline somewhere..near episode 17...i strongly thought they should of focused more on Nagi and Bob..However they decided to use many flashbacks which i considered as Fillers....Don't get me wrong ..i throughly enjoyed Tenjho Tenge!...Its Brilliant! especially the OVAs..episodes 25 and 26!
Furthermore...Many Japanese (Otaku?)/Cosplay icons are combined to characters such as Shin Natsume..is arguably a Combination of Final Fantasy 7's Sephiroth and Devil May Cry's Dante..(well thats my assumption!)...
Overall yeah..its great!
