Phantom The Animation is a short OVA about a young man, meeting an assassin while she was carrying out her job. Thus leading to the story of this OVA. The story is short and simple; a young man is taken by an organization and being trained by their number one hit man ‘Phantom’. Despite being only three episodes long, the story was well delivered. It was straightforward, sweet, and action packed. The animation is pretty good. The back grounds are well detailed; the action scenes are swift and smooth. However; the character design could use more work. It is not as detailed as the sceneries, whichis the only fault I could find in the animation. Aside from that, everything else was well done.
The sound is good, both the OP and the ED are remarkable, in my opinion. The voice acting is good, much better than what you’d expect from English dubs. Even though I don’t like dubs, but I have to admit that it was very well done. The inserted music is quite nice, nothing too awesome and nothing too bad either.

The characters are probably the best part of this OVA. All characters are unique in their own way, and you will probably not forget about them as soon as you are done with the OVA. The two main characters Ein and Zwei stands out on their own, they are well portrayed, they deliver their emotions without exaggeration, and we are even able to know more about their pasts. Other characters, despite their brief appearance, are also memorable. You are not going to forget any of them soon.

Phantom The animation has action, drama, and a bit of romance. It is a dark OVA, there are not much happy moments in it, and it is intense. All good things to be in a story about hit men. There are no happy moments. All there is is what people have to do to survive and go on with their lives. The characters will not change, they will grow and develop, especially the male lead, they will have to deal with their situations, with what they have to do in order to survive.
