The short uppercut is a technique in boxing derived from the orthodox uppercut. In Hajime no Ippo it is used by Hayami Ryuuichi as a counter against in fighters that dashed at him, making an opening for his Sunday punch, the Shotgun. It is also the parent technique of the smash and the one centimeter punch, both of which are short uppercuts that look like hooks. Mashiba Ryou's anti-in fighter uppercut has not been specified as being a short upper or a regular one.
