Taraba

Taraba is the imposing 'black' kid who wants to fiercely battle against a certain 'Echizen'. He had never seen him before though, therefore he accepted to fight Tetsuya instead, believing his name was Echizen. Taraba completely defeated Tetsuya, but he was later beaten by the latter when he joined with the crabs. He did not, however, die from being attacked by the crabs, seeing as he participated in part of Battle Bladers afterwards.

Trivia
Ironically, 'Taraba' is a kind of Japanese crab.
