Tomokazu Seki is a part of the seiyuu quartet of Weiss Kreuz led by Takehito Koyasu. He made himself a well-known name in the anime industry by sharing his voice skills which range from serious, comical to even deranged. His forte, however, is his ability to pull off Hot-Blooded characters so well it rivals Nobuyuki Hiyama (and they duke it out in They Are My Noble Masters).
Seki is also a heavy smoker and he uses it to his advantage to coarsen his voice whenever necessary.
He has several relationships with other voice actors. With fellow Weiss Kreuz member Shinichiro Miki, they're usually cast as buddies. With another seiyuu Ayako Kawasumi, they often play either couples, or Seki's character has an unhealthy, unrequited lust for Kawasumi's character. And finally, he has an alleged rivalry with Tomokazu Sugita (We cannot lose to him!), likely just because they have the same first name.
