So Satu isn't the CUTEST... but I think it'd be really fun to throw her into this and force her to adjust. A swamp lizard being made to try on cute clothes because she has nowhere left to go? Sounds super fun. Swamp outside the city burned down? Guess she lives here now. Really up to you if she's not fitting enough, but I believe it'd be an interesting source of conflict... at least for a little bit. I know that this is a place just to mess around and you probably don't want conflict- I just thought it would be a hilarious place to throw my DND character.
All characters are good to be here, and this takes place in feudal Japan, so conflict is okay, it's just that you cannot kill people.
