Kouki Miyata is one of the few male seiyuus who can convincingly play the cute boy or {{Bishounen}} archetype with the point that the first type is really voiced by a male rather than the usual shtick. This is mostly because of his uber high-pitched voice. However, he can play deep-voiced males as well.

He actually won the first seiyuu award's 'Best Male Supporting Actors' role.
