Black Cat is a science fiction manga by Kentaro Yabuki. It was published by Shueisha. It ran from July 10 2000 to June 14 2004. It received an anime adaptation in late 2005, which ran for 24 episodes.
Black Cat takes place in a fictional universe. The series follows the legendary assassin Train Heartnet, known as Black Cat, who becomes a bounty hunter, dubbed Sweeper after he leaves Chronos, the organization which employed him previously, and controlled one third of the world.
Honestly, this reminds me of Darker Than Black. Though it is paced much faster compare to it, given it only has 24 episodes. Having said that, it is a Shonen series, though it is nothing like most of the Shonen series, given it doesn’t use any of the formulas, and the story is much darker.
The fact that Sven sounds like that detective from Darker Than Black in English dub doesn’t help any.
Moving on, the opening is fine, it does what it is supposed to. But the ending, it just doesn’t match the tone of the show. A heart breaking or a dark scene at the end of the episode, and here comes a cheerful song! It is very jarring to say the least. Though the second ending is better.
After Train joins Sven, his attitude shifts completely. He used to talk with a cold and morose tone. But he speaks much more cheerfully. I suppose the ending could represent that change.
The opening kind of grew on me. the soundtrack is wonderful. The manga received the animated adaptation when it ended, and yet, they still managed to screw up the adaptation. I mean why did they needed to change the ending?
The anime is underrated. And I can see why. but I can also see why it is liked by some people, especially if this was the first anime they ever watched. The first anime is always important.
Honestly, if you’re thinking what to watch next, go ahead. Watch this one. You won’t be bored. But if you’re looking for a complicated plot, or a faithful adaptation of the manga, then look elsewhere. (A warning though. you’ll find that very rare in the world of anime. So far, Monster is the only one I have found personally.)
