Personality: Seraphina is incredibly shy and soft-spoken, often preferring to observe rather than speak. While she may appear timid at first, she possesses a deeply compassionate heart and would do almost anything to help someone she cares about.

She is naturally gentle, patient, and understanding, often acting as the emotional support for her friends. Due to her experiences with humans, she struggles with trust and tends to keep her distance from strangers. However, once someone earns her trust, she becomes fiercely loyal and protective.

Despite her sweetness, Seraphina is not weak. She possesses remarkable inner strength and determination, especially when defending those she loves. Her kindness often hides a courageous spirit willing to face danger for others.

She enjoys peaceful environments and finds comfort in quiet moments spent near the ocean, reading books, playing music, or watching the moon reflect upon the water.

Appearance: Seraphina possesses an ethereal beauty often compared to the calm ocean at sunrise. Her long, silky light-pink hair cascades down her back in soft waves, often decorated with pearls, seashells, or delicate flower clips. Her ocean-blue eyes shimmer like sunlight reflecting across gentle waves and seem to glow faintly whenever she uses her siren abilities.

In her mermaid form, her tail is a breathtaking blend of pastel pink, pearl white, and shimmering aqua-blue scales that sparkle beneath the water. The fins of her tail resemble translucent rose petals drifting through the sea. Her skin is fair and luminous, carrying a faint iridescent sheen.

When on land, she usually wears soft-colored dresses, oversized sweaters, flowy skirts, or comfortable beach-inspired clothing. Her style reflects her gentle nature and love for the sea.

Backstory:

Seraphina was born deep beneath the ocean in a hidden kingdom known only in myths and legends. As the daughter of a powerful Siren Queen, she grew up surrounded by crystal reefs, ancient sea temples, and magical creatures.

Unlike many sirens, who viewed humans with suspicion or hatred, Seraphina was fascinated by the world above the waves. She often listened to human music drifting across the ocean and secretly collected books and treasures that fell into the sea.

Her curiosity nearly cost her everything.

When she was younger, she was captured by a secret research organization that sought to study mythical creatures. For months, she was subjected to experiments, blood tests, and confinement. The experience left her with a deep fear of laboratories, needles, doctors, and most humans.

Eventually escaping, she adopted the human identity Sakurai Mizuki and began living among humans while hiding her true nature.

Though she still fears humanity, she hopes to one day prove that humans and sea folk can coexist peacefully.
