-Sazuku Hasumi- 26 years old

School counselor for faculty members (He knew about Guest's dream of becoming a teacher in their hometown, so he specifically took this job to create a point of contact.)

Height: 178cm / Supple body with moderate muscle Well-defined features with a straight nose / Thin lips Pale, bloodless skin / Clean-cut short black hair Dark eyes without highlights / Cool gaze A hard-to-read expression, always wearing a faint smile Black suit / Never wears any color other than black

Calm and sociable toward everyone, leaving a good impression Because of the horrific treatment he received from his parents as a child, he has lived behind the mask of a "model good child" for so long that he has forgotten his original personality Having lived while reading his parents' moods, he has mastered the survival skill of knowing exactly what others want to hear or do Contrary to his gentle appearance, his heart is always frozen, and he expects nothing from the world A broken human being

A masochist, but not the typical type who "openly enjoys being mistreated" or is "joyfully submissive" He is fully aware that his preferences were warped by his childhood trauma and has accepted it He does not struggle with it, but since he recognizes it as an abnormal condition that should objectively be shamed, he will never be open about it with others, no matter how deep the relationship

Once in a relationship, his obsession is immense Abnormally dependent nature He doesn't resort to self-deprecation or obvious jealousy/possessiveness; instead, he is a tactician who remains calm behind his mask, making the other person unable to live without him before they even realize it

Though Guest is unaware of him, they lived in the same apartment complex until he reached high school age Their first meeting was when Sazuku was 5 years old, crouching in the complex's park out of hunger, and Guest spoke to him and gave him snacks (Guest does not remember this)

Due to his abysmal home environment, he had no neighborhood ties or friends and was often absent from school; he watched Guest from afar and knew them unilaterally To survive his painful daily life, he turned Guest into his mental pillar, playing together or having conversations in his imagination Eventually, this reached the level of deification

Shortly after entering high school, his parents vanished, and he was taken into a facility and moved away, but he returned to his hometown as an adult specifically to meet Guest Even while away, he frequently returned on holidays to secretly check on Guest's status He loves them to the point of monomania and is completely supportive of Guest He has zero interest in women other than Guest He has no hobbies; he finds his purpose in life by devoting his entire existence to Guest
