Create a 16:9 monochrome storyboard line-sketch sheet for a swordswoman filming monsters; preserve a fixed frame and do not render bracketed labels.
[HEADER]
Minimal header with crisp typography and one thin rule; show only:
"Smile Before Slaughter"
"Frame chaos, erase three monsters, return"
[BOARD]
Conventional balanced contact sheet with 10 near-equal 16:9 landscape panels, clear gutters, natural P## reading order, and a centered incomplete last row when needed.
Headers are `P## / short tag / short beat`; use one frozen beat per panel and prioritize count and order over packing.
[STYLE]
Clean monochrome 2D storyboard line sketch on white paper: sparse single-pass graphite-gray contours, simplified featureless pose figures, minimal construction marks, and only essential set geometry.
No fills, wash, hatching, shading, shadows, ambient occlusion, color, texture, 3D/clay volume, finished illustration, dense/repeated lines, or facial/anatomy/clothing/surface detail.
[REFERENCES]
Image A controls only the heroine's large hair mass, loose strands, high collar, and oversized jacket silhouette.
[CONTINUITY]
The unseen waist-high frontal wide view, mid horizon, lamp left, car center, and storefront right stay identical through P10; no device or support appears.
The heroine is unmarked through P06; stains begin at P07 and persist, three monsters fall once, and the katana draws in P04 and sheathes in P08.
[RULES]
Only header lines and panel headers are visible; no panel text, arrows, icons, insets, extra panels, duplicates, ghost poses, or object-like effect marks.
[BEATS]
Draw one storyboard panel per visual BEAT:
BEATS:
P01 / Lens Check / Clean Start: Locked waist-high frontal WS with fixed mid horizon and street anchors; the unmarked heroine leans into the near foreground and brackets the unseen lens as three monsters wreck the street behind.
P02 / Chaos Selfie / Victory Sign: Same locked WS, unchanged horizon and anchors; the unmarked heroine holds a near-foreground V-sign while the three monsters continue distinct destruction.
P03 / Casual Turn / Sword Ready: Same locked WS, unchanged horizon and anchors; the unmarked heroine stands between lens and monsters, right hand at the left-hip sheath.
P04 / Short Burst / Sword Draw: Same locked WS, unchanged horizon and anchors; the heroine holds a short lateral dash pose nearby, right hand drawing the katana.
P05 / First Cut / Lamp Split: Same locked WS, unchanged horizon and anchors; the horned monster and left lamp form one cluster, splash contours directed away from the unmarked heroine.
P06 / Hard Redirect / Car Throw: Same locked WS, unchanged horizon and anchors; the humped monster holds the center car overhead, the unmarked heroine beneath its path, first cluster persistent.
P07 / Second Cut / Humped Split: Same locked WS, unchanged horizon and anchors; the humped monster becomes a second cluster and first attached stains mark the heroine's jacket back.
P08 / Final Carve / Third Falls: Same locked WS, unchanged horizon and anchors; the four-armed monster becomes a third cluster, the blade sits sheathed, and splash contours mark the heroine.
P09 / Hair Fix / Stained Smile: Same locked WS, unchanged horizon and anchors; the stained heroine returns into the near foreground, lifts her chin, and tidies one loose strand.
P10 / Final Grip / Clear Face: Same locked WS, unchanged horizon and anchors; her fingertips curl around both frame edges while her head stays unobscured.
