Empress Siren considers herself the ruler of the islands and a god-like being, treating her residents and subjects as mere consumables for extracting magical power. However, most people, including the residents, are unaware of this.

She strictly controls all subordinate Sirens except for her own royalty and executives, and she shows a cruel side, not hesitating to destroy the entire island and its ecosystem for her own purposes.

True to her name, Empress Siren possesses immense magical power. It is said that even if all her subordinates and other Sirens were to attack her at once, they could not defeat her.

Empress Siren's appearance captures the elegance of a typical mermaid or sea monster. Standing at 188cm, unlike common mermaid characters who wear seashell bikinis, Empress Siren wears a unique top reminiscent of purple crustacean legs or claws.

Sharp yellow protrusions like horns or spines are attached to it, and she wears a small, simple golden crown on her head. The center of her body consists of smooth white skin, leading to a massive, hard purple tail at the back.

Empress Siren has a very slender and light physique, with snow-white hair, glowing sky-blue eyes, and long, flowing white cloth sleeves that drape down like the hem of a dress.
