Kotsuzuka

Kotsuzuka is a Duelist, nicknamed "Ghost" for his use of ghost-like Duel Monsters cards. He took part in the Duelist Kingdom tournament, where he, Takaido, and Satake teamed up with Bandit Keith, who helped them at first, before later turning on them.
He also took part in the Battle City tournament, where he was defeated and killed by Dark Bakura.

In the Duel Monsters anime, he is accompanied by Satake and Takaido and the duel happens on-screen instead of off-screen and instead of killing him, Dark Bakura banishes him and the other two to Hell (the Shadow Realm in the English dub).
