The cast features organic supporting characters such as Bancho, Cobra, Yoshie, and various restaurant staff with mixed names fitting the sushi-restaurant setting, without any race- or gender-swapping of established figures or identity-focused arcs. The narrative relies on eccentric characters and humorous in-jokes rather than activist framing or identity politics as premise or driver, keeping thematic centrality firmly on exploration, restaurant management, and comedic sea adventures. The game includes a subplot that negatively portrays the group Sea Blue as hypocritical eco-terrorists who harass small businesses while ignoring corporate overfishing, directly countering progressive environmentalism tropes.

Restaurant patrons and staff appear in incidental fashion within a Japan-inspired setting, with no forced DEI casting, developer statements on representation, pronoun options, romance systems, non-traditional relationships, or character creation mechanics. No controversies or reception gaps tied to ideology have emerged, confirming the absence of progressive messaging as a core element.
