Zankyou no terror/Terror of the Echo or Terror in Resonance, have great suspence atmosphere, remind me a little of Death Note, but this series have more realistic story, though DN is better. It have decent detective plot about terrorist masterminds, and their message and true identity. Main characters: Nine, Twelve, Lisa Mishima, Five, Kenjiro Shibazaki are very charismatic, you will love their personage. I liked relationship between Nine and Twelve, and Shibazakis interrogation about them and their puzzles! Also, supporting characters are very likeable. Animation of characters, ambient is superb and artistic as it should be. Yoko Kanno, once againt proves her music masterpiese! My only complaint is that this should last longer than 11 episodes, we needed more Sphinxs doings, more of their traps and bidding with main antagonist/protagonist Shibazaki! All characters deserves more complex development! At the end I repeat, Zankyoun no Terror is something better of rest new shows. (show less)
