Typical among these sisters (Patreon)

This is a story of two twin sisters who are fighting all the time, Amy the redhead, and Missy the brunette, both girls were wet beds since they were little, and they have not managed to overcome that problem in all this time, they continually bother each other with any excuse.
If one of them wakes up wet, she is teased by her sister.
Amy loves boxing, while Missy who is an ordinary girl enjoys embarrassing Amy whenever she gets the chance. In the same way, she hates losing to her sister, especially if she is during a fight.

Currently they had a boxing match, probably the whole stage is something that is inside their heads

The defeat awakened the competitive spirit within Missy, and since then she has constantly trained with the desire to defeat Amy.
