Both have action. However, Darker Than Black has a bit more deep story line. Black Cat adds some humor into the mix up.
Both main characters have a dark past that lurks beneath the surface. Black Cat takes a more comedic outlook on the whole thing, while Darker than Black takes a more morbid outlook.
Both storys have a mysterious mainchara with great strenght
And some cute girls ^^
Characters are very similar (emotionless girl, main character is assassin who flees from organization and has a painful past, hard boiled detective and so one)
Also setting and story is somewhat similar
Bad pun not intended, one could call Darker Than Black a "Darker and Edgier" version of Black Cat.
They have very similar components and characters (organization of assassins/supernatural killers of which the main character is a part of, and each have different powers; mysterious waif emotionless girls; hero getting tangled up with figures from his past along the way, etc etc) but DTB does things with much more drama and blood. Also, the atmosphere of both just seem similiar as well.
+voice casts are ridiculously similar and soundtracks are reminiscent of each other
Black Cat and Darker Than Black both deal with assassins. While Darker Than Black has a main character with supernatural powers, Black Cat also has a main character who is highly skilled and is incredibly fast (this gave him the name Black Cat). I enjoyed both quite a lot since there was nonstop action and suspense. This is why I recommend Black Cat.
Though the storylines aren't exactly the same, fans of Black Cat may enjoy watching Darker than BLACK: Kuro no Keiyakusha. Both series revolve around a mercenary and include lots of action and a bit of the supernatural.
You can say those 2 main characters of both anime are assassin under a big organization .
i think the story line is bit closed , But 2 different attitude .
they both in tragic situation .
and same genre too - action
Both the main characters are assassin and the environment of both anime is kind of similar
the dub voice cast is similar. E.Jason Liebrecht plays both hei and train(Train="black cat" and hei="BK201"), Brina palencia is Yin and Eve who both have similar personality and past. the storyline is very alike. I was a fan of DTB and when I watched Black cat, I just fell in love with the series so yeah.
Similar concept. A group organization that has control over the people with powers which was caused by a military accident. Now it's them against the world just like darker then black but funnier.
The two series are similar in several ways. Both main characters work both with and against an organization which tries to control them but cannot, and the heroes of both have something that is just similar about them, they both eat a LOT and they both are voiced by the same actor in the English version. There is a real similarity in some of the tone of the story and the unique cast. Darker than Black is very well animated and has a great music score. I think if you like sci fi /mystery
Both stories run around a main character who's a loner and highly skilled at combat and have enemies with supernatural powers.
Bad-Ass individual fights super powered enemies in modern times.
Dark Place, an unique assassin, a special girl, and some loyalty. If you like "Black Cat", you can like (I think you love :) ) Darker Than Black too.
Assassination is a huge part of both of these shows, how it changes a person, how it is hard to escape, etc. There are also huge underground organizations in both of them. Black Cat is more fun, Darker Than Black is more intellectual, but both are exciting and executed very well.
Black Cat (TV) and Darker than Black: Kuro no Keiyakusha are both about assassins, but that’s not all they have in common. Both have a similar feeling and cast of characters, and there are quite a bit of shared voice actors as well. There is one thing that separates the two, however: the tone.
Black Cat (TV) has a bit of a lighter tone with quite a bit of funny moments, while Darker than Black: Kuro no Keiyakusha has a much darker tone, and there isn’t as many funny moments.
While I found similarities to both Cowboy Bebop and Black Lagoon in Darker than Black: Kuro no
