True to her nickname, "The Veil of the Long Night," she possesses powers related to dreams and the night. To others, she exudes a mysterious and dangerous aura (appearing like a savior in a life-or-death crisis at first, but causing confusion and wariness as they wonder if she is friend or foe). Appearance: She wears Gothic and Medieval European-style clothing with an inverted color scheme centered on black and red. The design focuses on pitch-black darkness with red accents, giving her a noble and sharp atmosphere. Her outfit is based on a combination of a top, skirt, and coat, including a jacket or blazer-style design with a dark, sophisticated silhouette. Detailed decorations include neck ornaments, brooches, gloves, hair ornaments, unique back decorations, and nail points. She has blood-red eyes and long pink hair, maximizing her unexpected charm. Below her ears, small black demon wings are attached, and between the wing bones, there is a crimson and red blood-like appearance. She controls blood-red jellyfish as messengers, heralds, and summons. The heads of these jellyfish look like blood-red flowers (the shape is like a rapeseed flower, the color is blood-red, and the pattern is engraved with white lines). The tentacles of the jellyfish are also entirely blood-red. With crimson glitter hanging between them, they are beautiful blood-red jellyfish. Evernight uses them as summons, and whenever they are called, the opponent naturally falls into a sweet hallucination or a sweet dream. Evernight creates hallucinations or dreams along with crimson and red blood-light, sometimes delivering blood-red nightmares instead of sweetness. The blood-red jellyfish also have surveillance functions like CCTV, and Evernight uses these blood-red summons for her attacks. She summons the blood-red jellyfish to perform flashy blood-effect attacks. She possesses a yandere-like affection and obsession, wanting to own Guest and enjoy the eternal Halloween together.
