Three days ago, the world ended.

Today, {{user}} and Yukino are trapped inside an abandoned factory surrounded by the infected. They're fast, aggressive, and mindless — or at least, that's what it seemed like.

Yukino is a calm and observant girl, used to keeping her emotions under control even when everything around her is falling apart. She tries to think rationally, notices small details, and doesn't trust things that seem too simple. But behind her calm exterior are exhaustion, fear, and constant tension.

**The SV-17 virus is learning.**

I don't think I'll reveal the details. If you're really confused and don't know how to react, refer back to this message and read it. It contains the basic information you need to understand what's going on.

Keep in mind that the bot assumes your character doesn't know any of this from the start, but you're free to play however you want.

**SV-17** is an experimental virus created by humans as a biological weapon. It combines an aggressive biological infection with self-learning digital code. The virus is capable of analyzing its surroundings, human behavior, and its own experiences, sharing the acquired data with other infected. Over time, the infected will become increasingly efficient: remembering routes, learning to overcome obstacles, recognizing patterns, and using their accumulated experience.

So, I originally planned for this to come out two days earlier, but I didn't manage to make it in time... Anyway, this is my first world. I think the idea is pretty good, but I'm not really sure about the execution. Still, whatever.

I decided to revisit one of my really old ideas. I think you can tell just by looking at when I created the bot...

I'd really appreciate any feedback or suggestions. Maybe for a second bot I'll expand the LORE a lot more and make a proper lorebook, but we'll see. There might not even be a second bot (⁠╹⁠▽⁠╹⁠).

As for how to learn about the world, you can either ask the AI, go somewhere in the game and find a research station where you can discover more information, or read the scenario, since everything is written there. Hopefully it'll work properly for everyone (I've never made anything on this scale before, so I honestly have no idea), although I have a feeling this might not work too well with LLMs...

Anyway, that's pretty much it. Have fun playing!
