Raise wa Tanin ga Ii

Romance anime involving assassins or organizations, little bit dark-ish elements and adult cast. Life and death situations Only one episode has been released of Yakuza Wife when I'm writing this but this was the first anime that came to my mind. Koroshi Ai is from "not that famous" studio so everything does not look flashy and brilliant but if you are just looking for good spicy love story between two characters while dodging bullets, this is a one to check out!  

Both revolve around protagonists who are "granddaughters of yakuza." A lot of other similarities as well! 

Both anime have badass female protagonists that are involved in the world of organized crime, Revy in Black Lagoon and Yoshino in Raise wa. Yoshino is the granddaughter of a yakuza boss similar to Yukio Washimine from Black Lagoon: The Second Barrage who is the daughter of a yakuza boss while Revy is a gun for hire that many times works for the mafia. Both Black Lagoon and Raise wa have strong but crazy, mentally unstable characters, in Black Lagoon those type of characters are mostly the women while in Raise wa those types are mostly the men. 

Both anime have a main female character that comes from a yakuza family but are down-to-earth and don't want to be in the world of the yakuza but when push comes to shove they show their badass side. Both anime have a highschool setting that mixes with the yakuza setting, Gokusen has the female MC be a highschool teacher and Raise wa has the female MC be a highschool student in her final year of school. Both anime have the male leads be difficult to deal with and they also like to resort to violence (especially Raise wa's male lead Kirishima) but they both end up admiring the badass, no-nonsense female MC. read more
