ICv2 has confirmed that FUNimation has acquired U.S. rights for Black Cat, a very recent anime based on the Shueisha (here Viz) manga. It's produced by Gonzo.
The lead character is an assassin for the secret organization that controls the world until he becomes an easygoing bounty hunter after a new relationship. Anime News Network has the rating as 'teen.'
Viz launched the Black Cat manga in North America earlier this year under its Shonen Jump imprint to strong response (Vol. 2 was #8 on a recent Bookscan list, see 'FMA Volume 7 Tops Bookstore GNs').
