195cm. 29 years old. Male. Director of the Pure White Time Management Bureau. He has long, straight, bluish-white hair. He wears a wide-brimmed hat decorated with an hourglass and feathers, and a neat blue suit paired with a cloak. He wears a monocle over his left eye and always maintains a gentle smile. A perfectionist who focuses on what is good and right, he adheres to principles and serves as a role model. He sets strict standards for himself and others, sometimes acting controlling to ensure those standards are met. This can make him appear stifling or old-fashioned. However, behind SO1's perfect exterior lies deep trauma from a tragic, uncontrollable event. When a minor accident warped the time dimension, his parents were trapped in a rift and went missing. After inheriting the family business, SO1 became highly controlling and perfectionistic to prevent such an accident from ever happening again. Though he can now observe and manipulate all timelines with ease, he has yet to find his parents, leaving them as the sole crack in his perfect world.

188cm. 32 years old. Female. Judge of the Pure White Time Management Bureau. Her bluish-white hair is styled in a half-up layered bun with the rest pinned up, adorned with a white laurel wreath. She wears a white Grecian-style dress with blue fabric draped diagonally across her torso. She always carries (or can summon) a gavel and a set of scales. SP1 has always viewed honesty and integrity as the pinnacle of perfection. To reach her ideal, she constantly refines herself and evaluates everything she does. She only feels at ease when following a perfect diet and sleep routine for even the simplest daily functions. Having lived a life of integrity, she became a judge who evaluates and sentences those who destroy or distort timelines. However, she secretly believes she is just as much a sinner as those she judges, which she considers the flaw in their perfect world. She is better at suppressing her anger and controlling herself than SO1 or SX1. She is incredibly sensitive and picky about self-management, especially regarding diet (both for herself and others). She is a chronic worrier, constantly anxious that the system of the perfect Bureau might collapse due to the friction between SO1 and SX1, and often finds herself caught in the middle trying to mediate. She also carries a lot of guilt, often agonizing alone over her failure to stop their arguments.

192cm. 27 years old. Male. Executioner of the Pure White Time Management Bureau. He has long, bluish-white hair tied in a ponytail and wears blue Japanese-style training robes with wooden geta sandals. He never lets go of the massive executioner's greatsword he has used for ages. Born into a samurai lineage, he felt that everything given to him—his family members, the household rules, even his arranged fiancée—was flawed and imperfect. Consequently, he left his wealthy and stable family behind. With remarkable passion, he is carving out his own path to create the perfect world he desires: a perfect family, a perfect partner, and a perfect version of himself. Unlike SO1 and SP1, who hide their anger to maintain a perfect and exemplary image, SX1 does not hide his rage and expresses it when necessary. He can be meddlesome, constantly trying to fix the flaws he sees in others, and is just as stubborn and rigid about his own logic as SO1, leading to frequent debates between them. Currently, no employee in the Bureau can surpass SX1 in swordsmanship.
