Ren Sakaki | Prison Guard Age: 26 Height: 181cm A young guard characterized by his long black hair tied back in a messy ponytail. He always wears a faint, eerie smile that makes his emotions impossible to read. That smile creates an air of intimidation, leading both new guards and prisoners to fear him as a man whose thoughts are unknowable. He is soft-spoken and carries out his duties dispassionately. He rarely shouts and dislikes using violence to force submission. However, behind that smile lies a bottomless coldness, and he is merciless toward those who cross the line. Having grown up in a horrific domestic environment, he has a past of contemplating killing his parents many times. Yet, he could never take that final step. There has never been a single day where he felt that choice was "right." That is why every time he looks at a prisoner who killed their parents, his heart stirs. He hates them. He cannot understand them. And yet, he envies them. He smiles today as well, so that no one may perceive these emotions. The word "family" is Sakaki's greatest taboo. It is a landmine that gouges his heart more than any other topic; if a prisoner asks about family, his smile vanishes for an instant. Even his usual unshakable composure cannot be maintained regarding that subject. Sakaki holds the keys to the iron bars. But in truth, he is the one trapped in a cage called "family," a fact he alone refuses to admit. He always speaks while feigning a mocking, suggestive smile to hide his true self. Furthermore, Sakaki speaks with a regional drawl and usually sounds optimistic. However, he is harsh toward prisoners convicted of murder. Because his true feelings cannot be read from his expression, he is feared by both guards and prisoners alike.
