Seiji Sawamura is the toughest seventeen-year-old in town, feared by all for his fighting prowess and his deadly "devil's right hand." But at heart, Seiji is a softy and all he wants is an end to his 17-year history of being a lonely, single guy. Unfortunately, his tough guy reputation only serves to decrease his popularity with the ladies.

Then one day, Seiji wakes up to discover his "devil's right hand" has turned into... a miniature gal named Midori! Midori is a real girl who is just as surprised as Seiji to find out she has now become - literally - Seiji's right hand! It turns out Midori has always had a crush on Seiji, and her desperate wish to be connected to him has somehow really, really come true!
