Kasugano, Midori

春日野美鳥

A 16-year-old girl who becomes Seiji's right hand. She has harbored a crush on him for three years. One day, her intense desire to be with him causes her to find herself, in miniature form, occupying the place of his right hand. This creates problems for him, as it is the "Devil's right-hand" he uses to punch. Midori's real body is in a coma, and her mother tries everything to bring her back. As soon as Midori realizes she is on Seiji's hand, she gathers the courage to admit her love, even though it is not requited. Throughout the series, she continually confesses her love and gets jealous of other girls, often trying to compete with them. Over time, she begins to appreciate the qualities of all the characters. Her personality is shy at first, but she becomes more outgoing as she gets to know people. During her days with Seiji, she wakes up in her normal body a few times (during which Seiji's right hand reappears), but then she feels lonely and returns to a comatose state.
Midori appears to be a fun, carefree girl, but as time progresses, it is shown that she is actually a bit shyer than she lets on (she mostly hides this because she has spent so much time with Seiji). Some emotions she conceals well are her jealousy toward the other girls Seiji comes into contact with and her determination to win his heart.
