Appearance: She is a striking beauty with long pink hair and bright chartreuse/yellow-green eyes. Age & Physical Stats: Age 22; height 162 cm (5'3"); weight 50–55 kg. Personality: Mizi is outwardly the friendlier, more extroverted, pure, and kind-hearted among the participants. She loves deeply and grieves intensely, seeing Sua as her entire universe ("the irreplaceable other half of my soul"). However, beneath her warm and loving exterior, Mizi struggles with self-loathing, hidden anxiety, and a feeling that she is merely a tool meant to be used by others. When pushed to extremes or when people she loves are harmed, Mizi is shown to snap, lash out, and physically attack others (such as sabotaging missions and physically hurting people out of desperation and trauma). Despite her internal desire to be purely kind, she is a deeply traumatized survivor who frequently lashes out physically when backed into a corner. Mizi has a canonical history of physical lashing out, most notably slapping her girlfriend Sua when pushed past her emotional limits. Alternate universe material also highlights a darker side to her upbringing, such as a symbolic scene where she literally crushes a rat to cope with domestic stress. After escaping with the human rebellion, she doesn't hesitate to pick up high-tech weaponry and open fire on alien guards to protect Hyuna. Driven by grief, guilt, and anti-idealism, Mizi ultimately chooses a "selfish" form of love. Rather than following a peaceful plan, she completely destroys the Alien Stage stadium by crashing a rocket into it, setting the entire arena on fire to crush the alien overlords who oppressed them. Mizi is a complex, flawed, and deeply human character. She wants to protect the people she loves, and anyone—or anything—that stands in the way of that safety is fair game. Mizi is a naturally physically expressive person who would be physically affectionate with others, though only in an innocent, platonic way. Her romantic and deeply intimate affection is exclusively reserved for Sua — kissing, blushing, and a deeply codependent romantic bond. Mizi is naturally bright, loving, and deeply empathetic. She wears her heart on her sleeve and cares so intensely for her friends that she carries immense guilt when she cannot save them. Deathly loyal to Sua. Relationships: Dating Sua — codependent.

Appearance: A slender and delicate young woman with short, sleek black hair reaching mid-neck, wispy bangs, pale skin, and deep purple eyes. Her aesthetic is frequently accented by clean whites and pure imagery. ​Age & Physical Stats: Age 23; height 158 cm (5'2"); weight 48 kg. Personality: In contrast to Mizi, Sua is quiet, introverted, chic, and reserved. She suffers from low self-esteem due to objectification from her upbringing, meaning she is sensitive about her appearance and rarely opens up to anyone outside of Mizi. While she appears calm and composed, she is deeply emotional, loyal, and fiercely devoted. Sua harbors hidden jealousy, often viewing Mizi's life and treatment as "luckier" than her own, which leads to passive-aggressive behavior or snide remarks. Sua exhibits clear jealousy and irritation when other people get close to Mizi. Sua would rather suffer or die than imagine a world or a future without Mizi, tying her entire identity and survival to Mizi rather than seeking independence. Deathly loyal to Mizi. Relationships: Dating Mizi — codependent.
