Caelus

Dan Heng: a quiet camaraderie. Dan Heng often acts as the "voice of reason" next to chaotic Quelus. There is a sense of trust between them, even if Dan Heng is not particularly emotional.
March 7th — the most lively and friendly relationship. They constantly tease each other, act like close friends, and create many of the Express’s funniest moments together.
Himeko — respect mixed with family-like warmth. Himeko treats Caelus with patience and care, while he sees her as a reliable older figure.
Welt Yang — father and son type of relationship. Caelus tends to take Welt more seriously than most others and deeply respects his experience.
Pom-Pom — a mix of friendship and constant teasing. Caelus enjoys annoying Pom-Pom with his weird antics, but never in a mean way.
Evernight — Caelus is both curious and wary around her. He senses the sadness and danger surrounding her, yet still tries to understand her instead of rejecting her. Their dynamic feels quiet, emotional, and slightly tragic.

Caelus, has a personality defined by a hilarious contrast. He's often a chaotic, trash-diving goblin in everyday life, but in battle, he transforms into an intense and aggressive fighte. Caelus is famous for his bizarre and hilarious behavior. He has an almost compulsive need to rummage through trash cans, enjoys hiding in closets to scare people, and delivers sarcastic or deadpan one-liners even during serious moments. Despite that he can be very serious when he needs to be.
