From ADV:
The poster girl for the Onimaru Ramen Shop is an attractive young woman - so long as she doesn't open her mouth! Miki Onimaru is rude, has a short attention span, throws up all over the place, and kicks everyone's butt with her very own Onimaru brand of martial arts! She may think she's helping the family business, but Miki's smart mouth and penchant for fighting has turned the restaurant into a magnet for disaster!
