WARNING: REVIEW CONTAINS MINOR SPOILERS.

Don't read unless you want to get spoiled or you've finished this anime series.

First of all, I must say people seem like appreciating the anime series based on the Light Novel and the Manga due to their popularity and their premises which have given from the story. Thus, they can get "spoiled" from the material reference which makes them understand the story better. But the otherwise can be said for the original series. Alas, people are somewhat underachieving the genuine or a stand-alone anime series even though it has very good premises of the story let alone the fans service as it has none of the stuff. Zankyou No Terror was one of the "victims" of this prejudice of the original anime series. It has a lot of premises for the story which leads to an eventful end. When the anime series title itself hints about the terrorism and bombs, it's more than those stuff essence. It's the series which tells more about the essence of philosophical matters and the irrational nature state of the human being. It also tells about the story of people who are looking for the authenticity of "surviving" or "staying" in this cruel world.

It tells about Nine and Twelve, two young boys who were disguising as the Spinx and looking for their freedom as the human being. They had a terrible past which they can't forget and they had the aim to make people realized about their existence. Mishima Lisa, a girl whose clumsiness and shyness can be exposed to be the main target of the bullies. Nine and Twelve had transferred to her school, and they met them under the blazing sun in a very hot summer. She had seen two different people looking at her.

Their "names" were Kokonoe Arata and Hisami Touji, but it wasn't their real names.

The premises of the story are very intriguing. As the psychological genre didn't show its nose until the mid-part of the story. The thriller is the main premise of the story due to the current state of Tokyo which had shown as massive terrorism since 90's era for the government. Hence, the mystery "played" on its own part when the riddles were needed to solve the case, it soothes my mind as I never saw something like this, the transition between one premise to another it's just so fluid. As for the drama, it's the main background of the story due to the aloof behaviour of the characters themselves.

The characters and their voices, I might say it's all good apart from some. Nine and Twelve were the centre of the story with the most character development due to their background. They have covered almost every flaw of the story which found to be a mass advantage for the series. As they weren't there not just to make the terror, but also aware of the safety of the other people surrounds the building, which means they never meant to kill people. Lisa Mishima is the next, apart from her sounds unimportant to tell, it's actually not. She played a deep role as she had intervened and influenced both Nine and Twelve's decision to do something. She also brought the stability of both and I might have to say, without Lisa, Nine and Twelve would never be that central for the story. As to the villain, I might say that they need to hire a good Voice Actor who can speak English, Five was very good as a villain letting alone the fact that she was a typical male villain who enjoyed the pleasure of "playing" with her opponents but I might say her English, I want to yell every time I hear that, it just sounds so horrendous and annoying. And about the other characters, I might say Shibazaki Kenjirou as a typical detective has played an important role, not just as police, but also a person who wants to figure about something for the sake of his ambition.

Overall, I might say it's a good one. I've rewatched it several times and I enjoyed it. The art is unique, the OP, ED, and soundtracks were memorable and possibly one of the best anime that I've ever watched. Okay, I think that's all. Agreed or disagreed, it's your choice, I don't mind it either.
