Sagwan

Zaguān (サグワーン) is a secondary character in Beastars. He lives on the third floor of the Hidden Condo, found out by Legosi while doing ramen delivery.

Zaguān introduces Legosi to the life and mindset of seafolk while visiting Sea District 3, as he almost gets devoured by fish Porikokos out of misunderstanding. He describes the life cycle as fated by the ocean and that "predator" isn't a word used.

He teaches two key phrases that end up saving his life in Chapter 141-- "Daba-baba Legosi ponpo-robú" (My name is Legosi) and "Agaga papubu daba goma bída" (I am friends with a spotted seal).

It is also noted that he privately lives in the nude as aquatic life does normally.
