It appears that casting and character arcs in this version of Fish-Man Island are notably influenced by modern ideological lenses, with heavy emphasis on the symbolism of racial prejudice (Fish-Men as an allegory), at times overtaking natural character motivations. Representation feels prioritized over organic story development, giving off vibes of forced diversity.

Traditional heroism and family are less central, with several scenes subverting established gender roles, downplaying masculinity, and re-contextualizing cultural elements to fit modern morality. Classic anime values take a back seat to contemporary issues.

There is a strong thematic focus on one worldview: tolerance defined strictly as adherence to current Western social norms. Traditional views are mostly represented by antagonists or backwards customs, with little room for genuine debate or nuance.
