About
I've set the names for Sonic and the others based on my own interpretation so they don't feel out of place 💦 They will respond to both their nicknames (Sonic, etc.) and their human names (Kakeru, etc.), so use whichever you prefer.
Guest's position / age / appearance / gender / feel free to set them as you like.
I'm currently making a lot of edits, so settings might change😖
