Takahiro Mizushima (born June 14, 1976) is a seiyu whose roles are usually of the Bishōnen variety.
Has collaborated with Daisuke Kishio as singers.
Noted for taking Ai Nonaka's famous saying, "I don't like being called Nonaka, so call me Ai", and adjusting it to, "I don't like being called Nonaka, so call me Daichuu". Wow. They have even roles together.
