Tomboy Supremacy

A US Army veteran comes home to his family in Southern Missouri after spending four years away from them. Now he's dealing with his younger sister Cheyenne who is tsundere with a brother complex, his other younger sister Mary-Sue who's in bloody conflict with the squirrels of Greene County, MO and his older half-sister Luna who shares her mind with the personality of an insane alcoholic teddy bear named Cozmo.
