Miki is the new poster girl for the Onimaru family ramen shop (usually shortened to just Onimaru). Though 20 years old, she still pretty much has the mind and maturity of a 12 year old child, with a corresponding energy and fiercely competitive personality that makes her stand out. She is often seen to start fights and competitions; her physical strength is admirable and her fighting style is frantic and unpredictable. Violent as she may be, Miki is a caring and kind-hearted girl who is keen to help anyone in need. This sweet-gentleness comes to the forefront when she is intoxicated, turning her from a crude tomboy to the very portrait of an ideal Japanese-Lady (or Yamato nadeshiko).
