In our view, “One Piece Log: Fish-Man Island Saga” appears to make narrative concessions by foregrounding themes of racial prejudice and systemic oppression, echoing modern sensibilities rather than staying purely within its adventure roots. Representation and identity are placed front-and-center, and at times certain diverse characters are given an idealized, almost flawless treatment.

The saga uses allegory to critique discrimination and, in the process, sometimes undermines traditional values or depicts aspects like familial loyalty and hierarchical leadership as obstacles or even complicit in injustice. It leans into cultural revisionism for moral lessons that feel quite contemporary.

Storylines paint alternative views (especially those not aligned with modern moral frameworks) as villainous, prejudiced, or simply ignorant. The show elevates a singular, progressive perspective, with no genuine internal debate or serious challenge from more traditional attitudes.
