Anime fight scene in a cursed forest

Here's my prompt: A cursed ancient yokai forest, deep night. Towering trees twist like demon claws, rotting shimenawa ropes coiled around their trunks, black mist churning across the ground, pink-purple spirit flames (onibi) hovering and flickering between the trees. An oni warrior girl (character reference "ONI WARRIOR": long black-purple hair in a high ponytail with red hair cord, a pair of pink-white oni horns, black Japanese-style samurai armor with a short armored skirt, sakura-petal accents, gold rope belt with red tassels, black thigh-high stockings and armored high-heel battle boots, carrying a cursed katana in a black sheath — its blade glowing an eerie pink-purple) stands surrounded by a horde of yokai: warped black shadow-demons with crimson single eyes and hooked claws, closing in through the mist in waves. [0-3s] Combat erupts in the first second: close-up on her hand gripping the hilt — then the draw! An iaido quick-draw slash sweeps out, a crescent of pink-purple sword energy tearing the darkness open; the three nearest yokai are cleaved through, bursting into scattering black shards and ash. Spirit flames instantly ignite along her blade, a small pink fox-fire spirit spiraling around her. She kicks off and dashes into the horde, black mist splitting before her. Camera snaps from the draw close-up into lateral high-speed tracking, with a single-frame freeze as the energy wave passes.

Black energy bolts rain in from all sides; she parries each with flicks of her blade, sparks and spirit flames scattering. Camera orbits her position at high speed, micro slow-motion punched into key strikes, her blade trailing pink-purple afterglow across the frame. [6-9s] The great yokai appears: deep in the forest the black mist surges like a tide, swallowing the ancient trees — a colossal demon beast emerges: an oni-shaped titan several stories tall, plated in black chitin laced with crimson patterns, a single horn burning with black flame, a point of crimson core-light glowing deep in its chest. Its roar blasts the mist apart; its massive arm hammers down — she darts back as the impact shockwave flings yokai and shattered timber aside. All the onibi flare at once, pink-purple firelight illuminating the battlefield against the titan's black-and-red. Low-angle shot from behind her selling the titan's oppressive reveal, camera pulling back fast with her retreat. [9-12s] Cursed blade unleashed: she levels the katana and exhales a battle cry — the blade's pink-purple glow erupts, spirit f
