The film lacks LGBTQ+ characters or non-cisnormative identities. The plot centers on a conventional romantic pursuit between a male protagonist and a female guide.

Ayuuru serves as a significant guide, yet the narrative follows traditional romantic tropes. There is no evidence of subverting gender hierarchies or challenging standard masculinity.

The tropical setting and the inclusion of a local girl suggest a move away from Western-centric perspectives. This framework allows for potential cultural exchange during the quest.

The story functions as a classic quest narrative centered on a legendary fish. It lacks explicit themes regarding secularism or critiques of institutional power.

Ushio possesses strange powers, but these appear to be standard fantasy elements. There is no indication that these abilities represent neurodivergence or physical disability.
