DISCONTINUED
I regret to say that I've stopped working on this idea in favor of what I had originally planned, which you can find in the Fate/stay night fanfic section under the time "You Are My King". Or, rather, the prequel to what I had originally planned. I've also begun work on the sequel, which would be this, as the two can be viewed as their own separate stories. Both are part of this bigger idea I have (that I began back in 2013 or so and since then has gone through quite a few changes, though the basis remains the same).
The reason I stopped working on this cross-over is because I found that having Revy and the cast of Black Lagoon in the story really didn't add anything to the overall story I wanted to tell and were, at the end of the day, just me thinking it'd be cool to include them. But, as it turns out, well...
Anyway, below is a re-post of what I had in mind for this cross-over:
Alright, so here is what I had in mind for Hero Fall involving Rock and Revy.
Basically, as established in the first chapter, Rock and Revy are in Japan days before the Holy Grail War because they are delivering a catalyst to Medea's Master, who I heavily based off Atrum Galliasta from Ufotable's UBW adaptation and, on the side, since they're there and might as well, to enter negotiations with the local Yakuza group for Balalaika (who obtained the catalyst for them, paid their way from Roanapur to Japan, etc.). Rock at this point (as it's several years after the main events in Black Lagoon) is more deeply embedded with his darker side (as seen in Roberta's Blood Trail) and Revy is, well, more loathsome (read: lonely) because of it. She's cynical, racist, and prone to drinking and fits of violence—more-so than before—and, I had planned, to have her retreat further and further into her shell as the story went on.
Hm. Anyway, after she winds up as the Master of Caster and after they battle Lancer (who at this point is under Kotomine's Command Spell), which leaves Revy injured and unable to do much, she reluctantly decides to bring Rock in, and from there it just goes downhill. Rock sees the Holy Grail War as an opportunity to change the fate of Roanapur, as Chang says his actions would in Roberta's Blood Trail but ultimately didn't go the way he wanted them too. This is his second, big chance, so to speak.
Since I was mainly going to follow Heaven's Feel in terms of how the 5th War pans out, let's just say with Rock being a player things get even worse. Plus there are other things that would've been revealed in Ayako and Bazett's storylines which pave the way for Minds of Steel, which is set immediately after.
In Minds of Steel, the city of Roanapur is where the characters go to find a certain red-haired puppeteer. Also there's a Canaan cameo (Bazett, upset about her arm-which Kirei cut off in Hero Fall-wanders into the Yellow Flag and has a chat with another one armed patron. Yes, it's Alphard.). Among other things (like Caren playing video games with Lotton, Sawyer, and Shenhua or Lancer and Bazett working for Balalaika).
Again, if anyone's interested in the story still, and doesn't mind that Revy and Co., look out for You Are My King and the new (or should I say, old) version of Hero Fall, which'll be under the same name. Oh, and if you see that the author is different, don't worry about it. A friend is hosting them for me.
