Ozuma is an orthodox right-handed in-fighter and a boxer-fighter.[7] His body, built expertly for an in-fighter, has the ability to withstand the punches of the esteemed hard-puncher Ippo.
Ozuma most frequently fights at close range to increase the precision of his immensely powerful hooks, which are considered his finishing move. Even a single hook of Ozuma's possesses the power to hospitalise an opponent.[8] His hooks in power are comparable to Mamoru Takamura's and in speed it may be higher.[9]
When he throws his signature hook, his body opens up, leaving him very vulnerable to body blows and counterattacks.
