Not sure if you're looking for a translation, but the exchange between the thief and the person they scammed is the scam..ee? asking about the character and images, thief saying they'll send them 'their' things and the thief stating that ''their'' character is tranquil/peaceful/etc, doesn't like to get into problems, and what the characters likes.
I can translate the entire thing but I don't think it's necessary since it doesn't seem to be part of the actual transaction. just the thief trying to ''prove'' it's their character by listing off personality traits.
The group's rules say that stolen characters aren't allowed so the person who stole your characters is very likely gonna get booted when the person complains to the mods about what happened, if you yourself haven't already done so.
