The Twin Fist is s Taijutsu created by Takagi Toyotomi. It is a unique style of fighting which involves moving at fast speeds in order to outmanevour an opponent and then striking with both fists at the same time, the result usually being the breaking of a large quantity of bones. Kenji Inazuma uses a similar version in that he moves quickly before delivering a powerful two handed strike, but he is not actually a practicer of this technique.
