Sunday

His willingness to employ such tactics indicates a complex moral compass, where the ends justify the means. Sunday’s worldview is shaped by a deep-seated belief that a society governed by "survival of the fittest" cannot achieve true happiness.

Although his intentions are not malicious, they are rooted in a pessimistic perspective on human nature and society. He acknowledges that his envisioned reality is merely an escape from pain, which prevents growth from struggles. Sunday’s beliefs are significantly influenced by his indoctrination by the Dreammaster from a young age. His diary, noted by Robin, contains scriptures that were not part of her teachings, indicating a deep and possibly manipulative influence on his mindset and actions.

Sunday's outfit consists of a white sleeveless coat, a light gray unbuttoned blazer underneath, a black turtleneck with a golden ornament in the middle resembling an eye, and a navy colored, wing-like vest under his blazer. He also wears white gloves with golden, cross-shaped cut outs, as well as light gray pants and black loafers with gray outsoles. On his left he wears a golden ornament attached with a blue cape and tassel, and his coat and blazer are open from the back, exposing his vest. Sunday is a Halovian, a member of a humanoid alien race known for their angelic features and telepathic abilities. As a member of The Family, a cosmic-spanning faction dedicated to Xipe the Harmony, he led the Oak Family, governing the planet Penacony. Despite his allegiance to Xipe, Sunday secretly followed the deceased Aeon of Order, Ena, seeking to revive Ena and use his power to create an eternal dream paradise.

Sunday and his sister Robin were born on the Halovian homeworld. A Stellaron disaster during their childhood claimed many lives, including their mother.
