Kalbi

Kalbi, also known as Kalbi the Butcher, is one of many contestants that partook in Esdeath's tournament.

Kalbi is to be a very large, well-built man, with a bull-like head. He's got yellow eyes, a large hoop ring running in between his nostrils and small horns on top of his head. He wears penny loafers, a pair of cargo shorts with a red sash around his waist and dons a black leather jacket that roughly stretches to his chest. Additionally, he sports black wristbands with a logo of a red bull on them.

In the manga, he also wears a large chain connecting his collar and belt, which is omitted in the anime.

Kalbi participated in Esdeath's citywide martial arts tournament to obtain the cash reward. In the final match of the day, he was set up against Tatsumi. Feeling confident of his victory, Kalbi taunted the young man due to their size difference. When the battle was underway, Kalbi was quickly pushed back and, moments later, knocked out with a heavy kick to the skull from Tatsumi, leaving him on the floor with a painful legacy.

It is unknown about Kalbi's fate afterwards; presumably, he might've been sold as a slave by Esdeath, or being incapacitated for his injuries and retired from wrestling.
