Detailed Review
Now let’s analyze why the Clevatess character resonates—through narrative, voice acting, and artistry.
Script & Character Writing
The writing reveals masterful transformation of the Clevatess character—from a force of destruction to a reluctant guardian questioning morality. Each monologue and silent moment unpacks another layer of internal conflict, especially in scenes where Clen hesitates to raise his hand, illustrating both fear and restraint.

Voice Performance
The portrayal of the Clevatess character benefits heavily from nuanced voice acting.
- Yūichi Nakamura captures duality with gravitas as Demon King and innocence as Clen. His deep tone morphs artfully into softer cadences, a testament to his emotional range.
- English dub (Sean Letourneau) mirrors this shift effectively, preserving the character’s weight and vulnerability.
Without iconic voice portrayal, the moral ambiguity of the Clevatess character wouldn’t carry the same emotional power.
Visuals & Sound
This section shows how animation and sound underscore the Clevatess character’s journey.
- Character Design: Beast King visuals—horned silhouette, heavy-set armor—loom oppressively. In contrast, Clen’s soft features, torn clothes, and wide eyes suggest fragility.
- Cinematography & Lighting: Dark, muted palettes cloak Beast King scenes; lantern-lit, warmer hues follow Clen moments. This visual polarity reinforces thematic change.
- Audio Landscape: Deep, bass-laden roars and thunderous footsteps transform into soft winds and childlike breathing when Clen emerges. Music shifts—from war drums to low piano—tracking emotional arcs.
