Minami Hiroki

Appearance
His eyes are heavily squinted, so it appears as if he has his eyes closed, and had his brown hair parted midway since he was a child.

Personality
He is a relatively calm person and prefers to end a dispute by doing a dogeza which usually freaks out the respective person (by his way of doing it).

Minami is the sort of fighter to use dirty tricks during matches.

Minami is strictly passionate about karate and believes it is an art to find and purify oneself, instead of an art for fighting.

He appeared to be a bit of a playboy, as he states he is dating about 5 girls at once, although it is revealed to be a lie. He also seems to enjoy going on group dates. He has been dumped a lot.

Ability
Minami is a practitioner of Kaburagi-Ryu a variant of Gōjū-ryū (剛柔流), which is one of the main traditional Okinawan karate styles with "hard-soft style" techniques.

Minami’s main weapon for combat is a pair of tonfas, due to his belief that only someone who has mastered armed combat can be called a true karate-ka. He has been shown to be very strong and fierce when fighting with them as if they are part of his body. Also Minami himself has mentioned that his guard with her tonfa is as strong as a castle wall.
