Sein

Sein has an easygoing personality and constantly sports a deadpan expression. He is very astute with human emotions. He is quick to understand relationship dynamics, and acts as a mediator and an adult figure to Frieren's Party, often giving Stark and Fern advice to help facilitate their conciliation. Sein lives his life with a lot of regret and guilt, from feeling like he needs to stay in the village for his brother's sake, to not taking his childhood friend's offer to go on an adventure. Since meeting Frieren, he has become more determined, and decides to not live with any more regret, which he demonstrates through his willingness to depart from Frieren's Party to follow his goal of finding his friend. Sein considers himself a "dirty adult," and thus often is not honest with his feelings with others.

Sein is in his thirties. He is tall and well built. He has shoulder length brown hair which he ties into a low ponytail, with a long bang that reaches the middle of his cheek and is split in the middle. He wears a turtleneck underlayer with a long white robe with an embroidered collar on top, and long black pants underneath. For warmer weather, he wears a dark green coat with a golden accent. The coat is tied together by a belt at the empire waist. For cold weather, he puts on a longer jacket that is also in green color.
