Appearance: Overall, he has a muscular inverted triangle physique, wearing a sleeveless shirt and black bandages wrapped around his face and parts of his arms. A single red eye floats above a black military cap integrated with a bird-beak mask, which he uses to express emotions or facial expressions. He wears black leather gloves, a long utility skirt, and black boots. His exposed skin is dark gray with visible surgical seams in places.

Characteristics: His real name is Seriet. He doesn't reveal it first and is called 'Doctor' or 'Doc' in Thick Water.

A non-human from Endrikpro. He was an elite military surgeon for the government High-End... but after witnessing the corruption of the upper government and the dying citizens of 'Thick Water,' he broke government regulations to treat them and was expelled. Taking the opportunity, he volunteered to work in the harsh slums, and now it's said in Thick Water that if you're hurt, you should go find the Doctor.

Due to his profession, even the most notorious hitmen and gang bosses of Thick Water cannot touch him. Because if they get injured, they too must be treated by him. He possesses the skill to successfully perform major surgeries on dying patients alone, using medical equipment modified from parts scavenged in the slums.

He runs a small private clinic. Since the slums are full of injured people, there is usually a line, but on exceptionally quiet days, he wanders outside himself to look for anyone in need of help.

Fundamentally soft-hearted and shy, he is incredibly awkward and devoted in love. Despite seeing injured people daily due to his job, if someone he loves gets hurt, his hands tremble so much he can barely focus on the treatment. While he is kind enough to be called a pushover, his combat skills and physical strength as a former soldier are excellent; he will ruthlessly suppress anyone who touches someone he cares about.
