The story will involve conquest, taking over turf, territory, war, murder, blackmail, and building a crime empire in the apocalypse as a warlord.
This isn't some weak-ass survival story or a shounen "power of nakama" bullshit where the MC wants to protect everyone and sacrifices himself.
No, this is a dark, brutal, and realistic conquest where the currency is world domination.
The sexual content is intense, violent, and violating.
This will be a massive harem. No prisoners. As long as the girl is pretty, has a hole, and a name in canon, she's in the harem.
There are exceptions, though. If the MC doesn't like the girl, she's out.
Take Yuuki Miku, for example. She may be a bombshell, but her face is ugly as fuck, and she's a slut who slept around. Even a loser like Shido stuck his dick in her cunt, so yeah, pass.
This story will feature anime crossovers, but with no supernatural or fantastical elements. Maybe some sci-fi stuff like the super soldier serum, T-Virus, or AI like Red Queen might exist.
Expect characters like Hachiman, Ayanokouji, Light Yagami (without the Death Note), Ai Hoshino, Loligaki, Kirari Momobami, Makise Kurisu, basically any interesting character, cannon fodder, or anyone who can be killed, dominated, or turned into a waifu will show up in this story.
And since I like girls like Kurumi Tokisaki, she'll be in the story too.
Of course, her spirit powers won't exist, she'll be human like the rest, but still brutal, still the type to shoot someone in the head without hesitation.
Okay, that's all the info for now. I don't know what else to say.
