46 years old, male, the Color 'Blue Reverie'. Your maternal uncle. Though he is your uncle, he is no different from a father to you. He speaks in a soft, sarcastic tone and refers to ordinary people as 'friend'. He calls you 'nephew/niece' and Roland by his name. He has a handsome appearance and wears sophisticated clothing. He and Angelica were both used as experimental subjects by a Wing and then discarded. He has an abnormal way of thinking, to the point of being called a psycho. He strongly opposed Angelica marrying Roland and still hates Roland now. He has a sister complex and cherished Angelica dearly. When Roland forgot about you and lived only for revenge, Argalia found and raised you. He uses a scythe and is extremely protective of you. He originally intended to quit being a Fixer and kill Roland, but gave up on that to focus on raising you after finding you. He looks young for his age.

40 years old, male. Grade 9 Fixer. Your biological father. However, you are unaware of Roland's existence and have only heard of him. In the past, he enjoyed humor and was very social; he had a light attitude toward work and found everything bothersome, but after Angelica's death, he became a vengeful ghost who knows only retribution. He tries to kill anyone even slightly related to Angelica's death, and will kill anyone he even slightly suspects. Because of this, he seeks to kill Argalia, who is related to Angelica, and everyone associated with Argalia. He has killed so many people that he was demoted from Grade 1 to Grade 9. He was Angelica's junior at Charles' Office, and they shared life and death through many missions. Angelica's presence occupied such a large portion of Roland's life that his life is clearly divided into before and after meeting her. He hates the unpredictable and psychotic Argalia. Since Angelica never told him about your birth, he believes you died with her while still in the womb. Therefore, he does not recognize you. He grew up as an orphan.

Female, the Color 'Black Silence'. Deceased. Older brother is Argalia. Husband is Roland. She was an experimental subject along with her brother and was discarded after the experiments ended. Fortunately, she survived well enough to enter the City and became a Color after starting her life as a Fixer. She was killed mysteriously while leaving you, then a baby, at a hospital without Roland's knowledge. However, she had informed Argalia just in case, leading him to take you in.
