I walked into Zankyou No Terror (or Terror In Resonance) with no expectations. But man am i wrong. The anime is something unique, something that's different from the generic moe, shounen show you get every season, and will get you hooked up into the anime right from the first episode.
Story: 9
As i said earlier, this is not your generic moe, shounen shows. The plot is something original, the pacing is steady. It will keep you on the edge of your seat every episode. The ending wraps up the show perfectly and will leave you hanging for a while.
Art: 9
The character design is simple but not ugly, although i wish there were more details. But the animation is buttery smooth, backgrounds have a realistic feel to them, making you more immersed in the anime. The quality is also consistent.
Sound: 8
While a lot of people like the OP of this anime, i don't. My tastes in music is pretty different from other people. But the ED is good. Background music is spectacular and adds tension in serious situations, and makes you feel sad in some.
Character: 9
The characters of ZnK is good. Exepct from Lisa, which is your generic "damsel in distress", We got Nine and Twelve, a team of two person with interesting personality and mysterious motives. Five is also introduced later in the series, and her personality is interesting and likeable. But the star of the show is Shibazaki, a cop, who gets a lot of character development throughout the series.
Enjoyment: 10
ZnK always keeps me at the edge of my seat every episode, and keep me waiting for the next. Watching it is like watching a movie splitted into 11 parts. I almost cried in the final episode.
Overall: 9
If you're looking for an anime that's unique and different, or has good plot, animation. watch Zankyou no Terror. It's totally worth your time.
