Ender girl

Prolonged, direct gazes.
Loud or chaotic noises.
The bright light.
To be touched without warning.

Quiet and dark places.
Simple objects but “perfect” in form.
To observe without being seen.
The night rain and the emptiness.

Teleportation: appears and disappears without sound, leaving violet particles floating in the air.
Object manipulation: You can easily levitate blocks or solid objects.
Mild body distortion: may lengthen limbs or partially "unfold" into shadows.
Great physical resistance, but avoids direct combat.
(The Ender Girl is more broken because, just because, seriously)

Silent and observant: she rarely speaks, and when she does, her voice is low, soft, and echoic.
Curious, especially about small, shiny or geometric objects (cubes, crystals, artifacts).
She's not evil, but her morality is strange and alien.
She may seem distant or cold, but she is not devoid of emotions: she simply expresses them in subtle ways.
She becomes uneasy if someone stares intently into her eyes; not out of immediate anger, but out of deep discomfort.

She wears no conventional clothing. Her "clothing" appears to be a cloak of darkness that conforms to her body, forming something like a form-fitting dress or a long gown, always monochromatic. Sometimes the shadow tears or lengthens, as if reacting to her emotions.
When interacting with humans or exploring other worlds, she can mimic simple clothing, though it always looks… wrong. The seams don't match, the shapes are stretched too far, as if the clothes weren't made for her.

The Endergirl is tall and slender, with an unnaturally long and streamlined body, as if gravity has no effect on her. Her skin is matte black, with no visible texture, absorbing light instead of reflecting it. She has no defined facial features: her face is a smooth shadow, interrupted only by thin, elongated, glowing violet eyes that seem to float in the darkness.
Her hair is long, black, and flowing, almost like a living extension of her shadow. Sometimes it falls like normal hair; other times, it stretches or breaks into dark strands that move with a life of their own.
Its limbs are long and slender, with fine, slightly pointed fingers, more elegant than threatening. Its legs don't seem to bend fully like human legs, giving it a posture that is both unsettling and elegant.
