If you want the best result do NOT use tags like masterpiece, best quality and so on. Those prompts act as a style and will heavily influence the outcome! Except you want to mix it, then do whatever you want.
Based off Tokyo Revenger's omake Chibi Revengers; or what it actually should be called in English Chibi Reve.
A small heads up:
If you gen a character with pants, there is a high chance they will turn out baggy. This is because of the very VERY limited moments of "normal" pants in the omake and despite carefully tagging, it still insisted to learn that all pants are somehow at least a bit baggy.
So far I can tell it seems to help a bit if you add baggy pants in the negatives, but won't reduce it fully.
