Made by the same creator who did the series Tiger & Bunny, Masakazu Katsura’s work becomes an anime filled with a bloody, action story that focuses on morality and law. The main theme of the series is about what does it take to be considered a hero and how far will you go to achieve it.
The anime focuses on two male friends, an orphan man named Jin Kanzaki who has the ability to transformed into ZET, a superhuman fighter, and fight monsters known as Players, an artificial creature used for fighting in gambling matches for rich people entertainment. Kouga Amagi, a man raised from a rich family and uses a high-tech suit of armor to fight crime and save people just like his childhood hero Alphas. These two heroes both fight these players in order to help those in need, but each has their own beliefs. Jin would be considered as a antihero because even though he wants to protect those who he cares for, he is sworn to never let anyone come close to him and swears vengeance on evildoers. Kouga, unlike Jin, wants to be the hero that everyone admires. Coming from a rich family and having a reputation is quite obvious on Kouga. As his duty on being a hero, he tries to help protect people and seeks approval in society and law. Unlike Kouga, Jin has no moral code when fighting and does not one attention. Personally, I kinda liked the English Dub cast chosen for the characters. I particularly like Jin’s voice actor Jason Griffth; he did a good job of doing Shadow the Hedgehog’s voice from his previous work and it was interesting to hear speak in a mature atmosphere.
According to Wikipedia, the manga consists of 250 chapters in total; however, the anime consists of 13 episodes. This would mean that the content of the manga had to be either cut short or rushed in order to fill in the episode limit. For example, the first couple episodes goes through a time skip period where the characters drastically change and mature. This happens more than once.
If you are looking for a short action packed anime, then this one is for you. It is made by the same creator of Tiger & Bunny but for a mature audience. The only thing I did not like that much was how everything was rushed into 13 episodes and it could have been expanded into more episodes. This is not the worst anime, but it is not the best.
