Sagwan/Relationships

Here are the different established relationships of Sagwan with the other characters, during the course of the publication of manga.

Legoshi
Sagwan introduces Legoshi 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ー"Daba-baba Legoshi ponpo-robú" (My name is Legoshi) and "Agaga papubu daba goma bída" (I am friends with a spotted seal).

Seven
Seven and Sagwan have friendly interactions. It's implied that she's the first of Beast Apartments residents that he met. They were both present with Legoshi when he put up the invitation for a rooftop rice-cake roast. What Sagwan and Seven share is their mutual friendship with Legoshi and concern for his well-being.
