Anglade is a marine biologist prodigy renowned for his extensive knowledge of both the sea and outer space. He possesses a tall, thin frame and distinctive long, unkempt deep brown hair, complemented by large, dark brown eyes. He typically wears a blue jacket with patches on the arms, left open without a shirt underneath.

His personality combines high intelligence with pronounced arrogance and self-centeredness. He frequently delivers lengthy speeches romanticizing natural phenomena and expounding on his theories about universal and oceanic interconnectedness. Initial charm, partly due to his appearance, often gives way to resentment among colleagues as his poor teamwork and resistance to direction become apparent. He operates independently, having abandoned his former colleague Jim to pursue the sea's mysteries through his own methods.

Driven by relentless curiosity, Anglade actively investigates supernatural oceanic events, particularly those involving the enigmatic brothers Umi and Sora. This pursuit frequently leads him to unintentionally endanger himself and others. He exhibits apathy towards both humans and the children of the sea, viewing them primarily as components within a larger cosmic puzzle, contributing to his morally ambiguous portrayal stemming from scientific obsession rather than malice. His complex relationship with Sora further highlights his defiance of authority and structured environments. His role consistently serves as a catalyst exploring marine biology, cosmic phenomena, and human limitations.
