Onosaka Masaya
Role: Keroberos
Onosaka Masaya is the seiyuu for Kero-chan's big form, Keroberos. Kero-chan needs two voices because when he goes into his transformation, his new shape is larger and...less cute. ^^;; (but it is!!) Of course, that calls for a deeper, stronger, and more masculine type of voice since the seiyuu of little Kero-chan is a woman.
