Houjou Seigo

The Scarred Doctor is an unnamed character introduced in Toaru Kagaku no Railgun: Astral Buddy. Formerly a researcher at Clone Dolly Ideal, he was working with Mitsuari Ayu on her plan concerning Yuuri Senya, along with Houjou Arei.

Appearance
The doctor has slicked-back, dark-colored hair, with a tuft hanging over the middle of his forehead. He has multiple scars across his face, with diagonal ones on both his cheeks (the right one extending across the bridge of his nose) and horizontal ones above his eyebrows. He wears a white suit, dark tie and dark trousers, with a white coat worn over them.

Personality
The doctor has shown to have so far be efficient,cordial and business minded when performing his duties as a doctor and during his first few appearances was shown to be kind and considerate enough to his patients when caring for them when they're hurt,showing himself to be a highly skilled doctor.

However it was later revealed that the true reason to his cold and deadpan demeanor was the fact he could not feel emotions and was slowly losing his senses,causing him to then "play the part" by acting,lying and pretending he "feels" things in order to avoid suspicion. This loss of physical sensation and emotion is severe enough that he has even begun to forget the memory of these experiences,as seen where he frequently tries to remember his previous experiences with these sensation in order to not forget them,but even remembering has begun to become difficult for him.

However despite the slow disappearances of his senses and feelings,he has still retained or tried to at least keep his care for his younger sister, as seen where he was scolding and worrying for her during her assignments and teased her for her lack of care in maintaining her appearance in public,showing that he still cares and loves her.

Background
In the past, the doctor worked as a researcher at Clone Dolly's third lab, Ideal. During the incident which occurred there, he was possessed by the out-of-control AIM aggregation and as a result, lost his sense of pain and taste, with his emotions gradually fading.

Sometime afterwards, he got a job as a doctor at Heaven Canceller's Hospital and did his job well despite his quirks. He was later approached by Mitsuari Ayu, who had come across a remnant of Ideal in the form of an Indian Poker card, and asked him to help with her plan surrounding Yuuri Senya and the 'Ideal' power that the lab had sought, with the possibility that it could heal him.

Abilities
The doctor is capable of performing rapid self-surgery on his face without a mirror.
