I will post the three main best hottest girls in Black Lagoon in the comment section.
Harem: Main girls are Revy and Roberta of course there are many girls to choose in Black Lagoon anime and manga as the manga is ongoing this fanfic will be both anime and manga! So the harem might be like 5 or more girls from Black Lagoon world!
No Harem: There will be only romance and at most 3 girls and the others just R-18.
Anyways go ahead and vote.
