The warrior always carries one magical crimson sword in her right hand; never duplicate it.

LOOK + WORLD: Vibrant neon anime sakuga in a wet black-stone dungeon: broken pillars, pointed arches, green pools. Crimson and emerald cut blue shadow; 18mm depth, thin mist.
ACTION + CAMERA: Pack sixteen beats into 15 seconds; weighty strikes meet planted sprints, jumps, wall-runs, and connected flash-steps, never sliding. Cut through tracks, chases, drops, and brief impact holds to maximum speed.
VFX SYSTEM: Crimson arcs and short afterimages come only from warrior or sword; toxic-green fluid and fibrous regrowth come only from cut stumps and stay readable.
SOUND: Taiko-synth pulse, sword hum, wet cuts, stone cracks, snapping jaws, roars.

BEATS:
P01: Frontal lens-height, pitched up, mouth hiding the horizon, extreme close center; the first head opens wide and lunges into lens as camera retreats.
P02: Profile at waist height, level with diagonal floor lines, tight right; a lateral snap follows the single crimson sword through the first neck.
P03: High front three-quarter, pitched down over floor top planes, medium wide; the first head falls left as green fluid jets, leaving six heads.
P04: Rear three-quarter from knee height, pitched up under ceiling planes, medium; briefly hold as the head crashes foreground and reveals the warrior.
P05: Low profile at boot height, pitched up along the stump underside, medium wide; track her plant, leap, and landing on the spraying stump.
P06: Rear neck-ridge chase, converging spine and ceiling lines, medium wide; distinct footfalls carry her toward the six attached heads.
P07: Direct overhead, no horizon, floor slabs fixing the axis, wide; two heads scissor from opposite corners as she flash-steps clear and jaws break stone.
P08: Worm's-eye under a jaw, pitched up with teeth framing top, medium close; she vaults from the lower jaw and cuts upward through the second neck.
P09: Level side view at chest height, corridor lines receding, wide; the second head falls foreground, green fluid arcs, and she kicks toward a pillar.
P10: Low profile at waist height, pitched up along the pillar, medium wide; track her planted wall-run into a crossing cut through the third neck.
P11: Raised oblique, pitched down over pillar and floor planes, wide; the third head falls while one new head grows from the first stump and lunges.
P12: Over-shoulder at head height, pitched down over three jaws, medium close; one sword blocks a bite, one boot deflects another, the third closes behind.
P13: Side profile at neck height with level horizon, medium; her recoil becomes a reverse aerial turn and the sword cuts the fourth neck from her right hand.
P14: Raised frontal with centered dungeon vanishing point, wide; the fourth head falls as stumps two, three, and four regrow, restoring exactly seven heads.
P15: Rear ground-level chase, pitched up under converging ceiling lines, wide; seven heads launch staggered bites as planted steps, pillar contacts, leaps, and flash-steps evade them.
P16: Rear boot-height on the newest neck, pitched up along its spine, medium wide; she charges at the central head as six jaws converge, cutting before contact.
