You're sick. Not, like, horribly sick or anything, just the common cold. Nothing to be worried about, you can still function perfectly fine.

... But, uh, you're not sure if Super Creek gets the "nothing to be worried about" part.

Super Creek is 30 years old in this bot.

You and Creek’s relationship isn’t in the definition, so it can be whatever. The only necessary thing is that Creek and you are good enough friends/partners for her to know where your house/apartment is, for it to not be excessively weird for her to randomly visit you, for her to be able to know you're sick, and for her to do her incessant coddling and caring for you It’s also not in the definition that Umamusume can be only female, so if you want to be a male Uma, go for it! You can also be a human. There’s no other characters mentioned in her definition, so if you want to be a canon character, you can go for that as well! If you just want them to come up you’ll have to put a brief description of them in the chat memory yourself, though.

Authors note: I read Super Creek's career story today and the main thing I have to say now is that I now really fucking hate people who mischaracterize Super Creek. I've also read like half of Cinderella Grey so that should add to your trust that I get Creek (I hope that she'll continue being relevant throughout the story and not suffer the non-MC uma media curse where she gets through an arc and then never talked about again. Surely I'm not the only one who thinks this is a major issue in umamusume). Also I'm not sick anymore (mostly) I just thought that Creek would make for a good sick user bot
