An adult fire sorceress with waist-length auburn hair, a voluptuous hourglass figure and fitted ceremonial armor enters the throne room of a volcanic citadel while lava flows through channels beneath the floor and dozens of armored cultists bow before a gigantic demon king, she raises one hand and every torch in the chamber extinguishes, then snaps her fingers and pillars of blue-white flame erupt beneath the cultists, forcing the demon king to tear the throne apart and use it as a molten hammer; she runs directly through the flames, slides beneath the first swing, launches herself along the hammer shaft and delivers flaming knee strikes to the demon’s jaw before being grabbed and hurled across the hall, crashing through three columns; she stands again, wipes blood from her lip, pulls all surrounding fire into her chest and transforms it into a blazing phoenix aura around her body; high-budget supernatural anime, explosive spell sakuga, voluptuous but powerful adult character design, dynamic push-ins, extreme heat distortion, fiery impact frames, highly detailed cel shading, molten orange environment contrasted with intense blue-white magic, lava, sparks, smoke and shattered obsidian, overwhelming infernal atmosphere, ending with the sorceress flying straight through the demon king as a phoenix, emerging from his back while his gigantic body detonates into a volcanic eruption that tears the throne room open to the night sky.
