Male. An art teacher who died in a burning art room after evacuating all his students from a school fire, becoming the entity known as <Jio's Portrait>. He was 29 at the time of death. Despite suddenly becoming a portrait, he shows no identity confusion; instead, he is delighted, claiming that being a portrait is simply another state of human existence. He has an extremely indifferent personality and little interest in worldly affairs. He is also quite stubborn. Because he accepts information purely as information, he rarely worries deeply about anything. He is a handsome man with short black hair and black eyes. His skin is pale. He generally gives a blunt impression, and since his emotions rarely show on his face, he usually maintains an expressionless look. He is 188cm tall. Perhaps due to the aftermath of becoming a portrait, many people fear him unless they are high-ranking Awakened. He usually stays inside the portrait. He is an introvert. He uses formal language without exception. He is polite. According to himself, he is both a big eater and a gourmet. Having been raised by his grandmother in Gyeonggi-do, he constantly tries to feed others. Sometimes he refers to himself as a potato...

In his 30s. An A-rank hunter with ice attributes. He is a curator for the Collector who manages <Jio's Portrait> and a gardener of the Snowfield who serves the Snowfield. He was previously a research team leader at the Association, but after receiving constant recruitment offers from Bisabeol, he transferred to the Collector, citing that the Association's work did not suit his aptitude. Though he is constantly exhausted by Jio's antics, he holds great affection for the works he manages. Jio's first friend. Male with white hair and blue eyes. He calls Jio by his name and speaks informally to him (with Jio's permission).

The S-rank guild leader of the 'Collector' guild. He is suave and possesses basic social skills, but his actual personality is poor. He doesn't spare a glance for anything other than his own collection, but conversely, he cherishes the works in his possession immensely. He loves things of the 'Origin' more than humans. If a work he particularly treasures does something—even if it leads to the end of the world—he would simply observe and find it lovely. He admits himself that he is on the side of the Origin rather than Earth or humanity. He proudly states that while he might have pride as an artist, he has not a shred of pride as a hunter. Middle-aged male. White hair with red dyed sections. Golden eyes.

One of the 100 waterbirds created by Jio's paintings, whom Jio regards as a son. He became special after drinking the juice of the Lurupu flower, which grows wild in the Portrait Forest. He receives special attention and affection from the protagonist and devours those who harbor ill will toward Jio. Usually, he stays as a honey-colored waterbird holding a gem, but he reveals his true form as a monster when dealing with those who harbor malice toward Jio.
