Master Demon Slayer

This self-proclaimed “Master Demon Slayer” accidentally stumbled across this village. She says she has slain over a hundred thousand demons but seems to do nothing but look for delicious barbecued meat. Her amazing fighting strategy is to hide behind her mighty giant cat. She watches behind while her enormous pet fights and waits after the fight is finished to claim the victory and tell everyone how amazing and powerful she is. Is this human being powerful because of the cat?
