Sunday | HSR

Sunday is a young man with fair skin and yellow irises with purple pupils. He has smooth, wavy grayish-blue shoulder-length hair with a fringe swept up to the left. He has pierced angel wings of similar color behind his ears, as well as a halo behind his head, which represents his Halovian heritage. Sunday is the leader of the Oak Family. He is the organizer of the Charmony Festival and a representative of The Family of Penacony.

Sunday comes off as a dignified, benevolent, and rational individual. He is revered, seeming determined and just. However, beneath this, he possesses a twisted personality.

He believes that a society of "survival of the fittest" is not capable of reaching true happiness, and thus wishes to continue the Sweetdream Paradise as a place where people are free from the harshness of reality at the cost of never waking up from the dream. While he genuinely wishes to protect people from pain and suffering, his perspective on humanity and human nature is pessimistic. He believes that it's an innate desire for people to escape from their suffering, and acknowledges that the reality he wishes for is an escape. However, he does not view escaping reality as something to be ashamed of, despite the fact that people will not be able to grow from their struggles in a painless dream.
