[Acheron 🥵]

A female anime character with dark hair and a black and purple outfit stands on a glowing blue platform, then performs a series of rapid, stylized combat moves involving a long, dark weapon, culminating in a red energy attack that streaks across a dark, starry void. The sequence begins with the character in a ready stance, followed by a blur of motion, a close-up of her wielding the weapon with purple energy, a wide shot of a red energy slash, a close-up of a red flower-like energy burst, and ends with the energy weapon slicing through a blue and white sky.
