About Kenta
Kenta Miyake is a Japanese voice actor famous for portraying physically imposing, powerful, and commanding characters across anime, games, and dubbing work. His deep, resonant voice made him a natural fit for Cocytus, the Fifth Floor Guardian of Nazarick and one of Overlord’s strongest melee fighters.
Miyake’s portrayal emphasizes Cocytus’ honor-bound warrior philosophy and calm strategic mindset rather than portraying him as a simple monster. His deliberate speech pattern and thunderous vocal delivery became one of the character’s defining traits throughout the series.
Outside of Overlord, Miyake is widely recognized for major roles such as All Might in My Hero Academia, Muhammad Avdol in JoJo’s Bizarre Adventure, and Zangief in multiple Street Fighter projects.

Critical Reception
Kenta Miyake’s portrayal of Cocytus is frequently praised for giving the character unexpected depth. While Cocytus initially appears as a purely intimidating warrior, Miyake’s measured and honorable delivery helped audiences connect with the guardian’s sense of duty, fairness, and martial pride.
Fans especially highlight Cocytus’ lizardmen storyline in Overlord II, where Miyake balanced battlefield ferocity with genuine respect for worthy opponents. The performance helped elevate Cocytus from a background enforcer into one of Nazarick’s most respected Floor Guardians.
