Katsumi Suzuki

voiced Toguro Ani in Yu Yu Hakusho: Ghost Files

Toguro is the strongest demon capable of passing through the Kikai barrier. He sees Yusuke's potential and decides that only Yusuke can give him the battle he has been looking for. Toguro cares nothing for world domination or destroying all humans, he wishes only to grow stronger and to be able to test his abilities.

Toguro was born a human, and was in love with Genkai, but after winning the Dark Tournament, he wished to become a demon and the two grew a mutual loathing of the other. Because of this, the battle between him and Yusuke holds even more importance to him.
