凍てついたオーロラに照らされた峡谷での壮大なユニコーンバトル

Epic dynamic scene, cinematic, 3D render, Unreal Engine 5, Octane render. In a frozen ancient glacier canyon under a starry sky with aurora borealis. A colossal, majestic white unicorn, its body crackling with intense blue-white lightning, its horn glowing transparent with concentrated energy, faces off against a black-robed adventurer. The adventurer is leaping high, mid-air, swinging a giant glowing red greatsword with molten lava textures. The sword and the unicorn's horn clash violently at the center, creating a massive explosion of blue lightning and red fiery energy, with a visible shockwave rippling outwards. The ground is icy and reflective, covered in cracked ice and snow dust kicked up by the force. Low angle shot, dramatic lighting, highly detailed, fantasy, anime style, vibrant colors, motion blur on the adventurer's cloak.
