A 'Black Lagoon Hansel and Gretel Fanfic' could be really interesting. It might explore the dark and gritty world of Black Lagoon with the fairytale elements of Hansel and Gretel. Maybe it could re - imagine Hansel and Gretel as two lost kids in the lawless world of Black Lagoon, with all its guns, crime and moral ambiguity. They could be used as pawns by different factions, or they could be the ones causing chaos in their own naive way.
Another concept could be alternate universes. For instance, a fanfic could be set in a world where the Lagoon Company operates in a more legal and regulated environment. This would completely change the dynamics of their operations and how they interact with other characters.
A great Black Lagoon Balalaika fanfic often has a deep understanding of her character. It should capture her tough and no - nonsense personality. For example, showing her strategic mind in handling the Russian mafia business.
I'm not entirely sure as it could be a very specific or even a made - up fan - created concept. It might be a fanfic related to 'Black Lagoon' that involves something about 'rock kills' which could potentially refer to a rock - themed or rock - music - related violent or dangerous element within the fan - written story.
A possible plot for a Black Lagoon Hansel and Gretel Fanfic could be that Hansel and Gretel are from a small village that is destroyed by a powerful syndicate. They are then found by Revy from Black Lagoon. Revy initially wants to leave them, but Rock convinces her to take them in. However, the kids unknowingly bring trouble as the syndicate is still after them. Hansel and Gretel then have to adapt to the violent world of Black Lagoon while also trying to stay one step ahead of the syndicate that is hunting them down. This could lead to a lot of action - packed scenes and also some character - building moments for both the kids and the Black Lagoon characters.
One common theme could be the relationship dynamics within the harem. How the different characters interact with the main character and with each other. Another theme might be adventure, as 'Black Lagoon' already has an adventurous setting, and the fanfic might build on that while incorporating the harem aspect.

Another approach could be to create a scenario where the Assassins' Creed's hidden blade technology is discovered in the Black Lagoon world. Different factions in Black Lagoon would then fight over this new and dangerous weapon.
