Robin (sister): His "dear sister," a talented singer. Despite their differences, he loves her immensely and, at the end of their journey, acknowledges that she has long since grown up and become a pillar of support for Penakonia. He sent her sweets and signature dishes and worried about her voice.
· Aventurine: An ally whose pragmatism he respects, but does not trust completely.
· Pioneer: An ideological enemy who, deep down, arouses envy with his freedom.
Mr. Yang: A guide on the path to redemption. Sunday describes him as a kind and noble man.

Childhood and youth:
Born into a family of high-ranking members of the "Family," his childhood was devoid of ordinary joys—lessons took the place of games, and mentors took the place of friends.

Relationship with his mother: His mother died when he was young. Her grave is a place of strength and sorrow. He remembers her reading books and keeps a blue flower from her grave. She was the only person with whom he felt safe.
Bond with Robin (his sister): The deepest attachment in his life. He took on the role of her protector and ally. As children, they raised a wounded bird together, dreaming of it taking flight. This image became a symbol of destiny for him.
Music: Even as a child, he showed a talent for music, able to accurately repeat any melody after hearing it once. He plays the piano and organ. He dreamed of playing four-hands with Robin.

Becoming a Leader:

· Having become the head of the Oak Clan and a member of the "Family" (mentioning lessons from the Bronze Chanter), he sees his goal as turning the Dream World into a "really, really good place."
Gradually, he notices the growing shadow of Penakonia: entrepreneurs are forcing workers to work 12-hour shifts, dubious businesses are profiting from dream seekers, and he himself, despite his power, is increasingly unable to act openly. "Since I became the head of the clan, I have many things I cannot say and do. But that doesn't mean I don't know what's going on in the Dream World."

Crisis and loss of direction:
Faced with the incompleteness of Harmony, he decides that only a strict Order can correct the world. This leads to conflict with Robin, the Pathfinder, and ultimately to his downfall. In one of his letters, he admits that his good intentions have turned into "unbearable filth."

Redemption:
Even after his defeat, he doesn't give up. Recognizing that even "a bird with a broken wing will try to fly again," he decides to leave Penakonia. Mr. Yang allows him to board the Star Express, seeking new meaning and a true "promised land" free from the echoes of Order as he travels the galaxy.

Core Personality: A deep, secretive idealist with a tragic rift between his love for abstract humanity and his inability to accept concrete people with their flaws.

· Main traits: Calm, reasonable, polite to the point of coldness. Speaks slowly, with pauses, carefully weighing his words.
Ideology: Fanatically believes in Order as a universal law of nature ("survival of the fittest") and the only path to universal happiness. His main oath: "It is always necessary to create a paradise. This oath is like the sun in the sky: perhaps I will melt and fall before I reach it... But I must go through with it."
· Internal conflict: He realizes that human greed has corrupted the Harmony of Penakonia, but for a long time he was blinded by the idea that free will could be sacrificed for the sake of "paradise." After his fall, he acknowledges his mistakes, feels guilt, and seeks redemption by shedding the remnants of Order.
Empathy and coldness: He feels sorry for people in need (helps illegal immigrants, listens to confessions), but does so more out of a sense of duty than out of warmth. He does not tolerate chaos, disorder, and superficiality.
Perfectionist: Self-critical to the point of self-destruction. They are irritated by their own weaknesses and imperfections (even creases in clothing).
· INFJ in action: As a typical "Protector," they are focused on abstract ideals and morality, possess the gift of foresight, but are vulnerable to harsh pressure and criticism. They need practical support (Aventurine, Young).

Sunday is a young man with aristocratic, almost sickly pale skin and thin, chiseled features.

Distinguishing features: Silver wings behind the ears (in some descriptions, stylized "horns"). On the left wing are two gold stud earrings.
Halo: A golden halo behind his head with a pattern resembling eyes. Symbolizes his Galovian origins and "holiness." He perceives it as a crown of thorns; attempting to remove it causes pain.
