Mangaka Kazurou Inoue
Summary: Seiji "Mad Dog" Sawamura is notorious for his fearsome right hook. Because of his image, most people from school, especially the girls, tend to stay away from him. During one of his loneliness bouts, Seiji wishes for a girlfriend and remarks that he would give anything in exchange for one. Lo and behold, his wish comes true the following morning, except that the girl happens to be attached to his arm, where his right hand should be.
Comments: Midori no Hibi is just hilarious. Add a couple of love rivals here and there, a mad scientist, a touchy foreign exchange student, crazy classmates, stalkers, and gangsters out for revenge, and you've got a winning formula for unadulterated entertainment. The cover designs are cute, too.
