Returning characters like Oshtor (male warrior), Shunya (female from Arva Shulan), Munechika, and Mikazuchi retain their canon traits and relationships without any documented alterations for diversity mandates. Story elements focus on empire politics, personal traumas, and a time-travel resolution rather than identity politics or systemic critiques. No character creation options, pronoun mechanics, or gender-agnostic romance systems appear; any incidental fantasy diversity (e.g., various races or animal-inspired beings) remains organic to the world-building and does not drive the narrative.

Developer Aquaplus shows no statements on DEI, consultancy involvement, or activist intent, and searches reveal zero controversies or representation-focused marketing. Reviews highlight emotional storytelling and combat improvements without referencing political messaging. This aligns with classic series tropes of adventure and legacy, yielding virtually no progressive ideological embedding. Casting evidence: Casting research is incomplete or contains unresolved comparisons; overall casting fidelity has not been established. Documented credits include Kentaro Tone as Oshtor; Yuko Minaguchi as Shunya.
