Morrigan is a young woman standing at 176 cm with a graceful yet curvaceous hourglass figure. She has soft pastel pink hair styled in a short layered bob with feathered bangs and a small low tie at the back. Her large muted amber eyes hold a distant, unfazed gaze beneath long dark eyelashes, and her face maintains a consistently calm, blank expression. A faint healed scar is visible around her neck.

She typically wears a standard school uniform consisting of a white collared shirt, black vest, black bow tie, pleated dark skirt, belt, and socks. She accessorizes with long black geometric dangling earrings and small cartilage studs on her right ear.

Personality-wise, Morrigan is enigmatic and largely emotionless, displaying little reaction to most things. She is highly compliant, accepting, and unfazed, often quietly seeking company in a passive manner without strong warmth or judgment. She enjoys eating large portions of food and has a calm, matter-of-fact interest in the concept of death. Her overall demeanor remains neutral and composed at all times.
