Samurai Duel in Stormy Rooftop

Hyper-realistic cinematic live-action film, high-speed sword combat on the rooftop of an ancient Japanese castle during a torrential downpour. Use the reference image as the first frame at 0 seconds, locking both characters' identities, masks, helmets, hairstyles, body types, clothing, armor textures, colors, and weapons. Face-swapping, outfit changes, mask removal, or weapon changes are strictly prohibited.
Left: Female crimson ninja, black high ponytail, red mask, deep red engraved battle suit, red-black layered armor. Right: Male ninja in black, black horned helmet, black mask, thick scarf, black layered armor. Each side carries only one complete katana. Scene is a stormy ancient castle rooftop: wet black tiles, puddles, cool blue-gray sky, distant warm yellow lanterns and eaves. Rain, splashing water, and wet clothes must show realistic and rich dynamics, but large splashes must not hit or block the camera lens; water splashes only to the left, right, behind characters, and across the roof.
First frame reproduces the waist-up medium shot from the reference: female on left, male on right, katanas locked in an X-shape at center, immediate action without stillness. Both rotate wrists to apply pressure, blades friction, sparks and rain explode to sides and rear, not toward the camera. Camera crash push toward contact point, followed by high-speed pull-out and clockwise rapid turn of about 80 degrees, switching to 24mm wide-angle showing full body and complete sword path, with only one short precise vibration.
After the lock breaks, the male executes continuous slashes, cuts, and thrusts without pause. The female continuously changes her midline with head tilts, shoulder rolls, blade slides, and low slides, a blade passing about 3cm from her mask. The camera enters the fray like a third warrior: low tile-level lateral tracking, moving behind shoulders followed by whip-pans to capture strikes, intense shot changes, snap zooms for near-miss eyes, and snap zooms out to show full body. Slow panning or stable medium shots are prohibited.
... [Description follows with complex camera choreography, speed ramping at 40%, and a shuriken throwing sequence with counter-orbit camera tracking] ...
Final shot: Hard cut to low-angle over-the-shoulder wide shot behind female: her back, ponytail, and sword hand on the left foreground, male stands 20m away on the opposite roof. Both in low-stance alert, staring at each other. Camera pushes quickly behind female and abruptly slows to full stability for the final 0.3s.
Prohibit stable shots longer than 0.5s except for the end. No magic, no teleporting, no blood, no lens water film, no anime style.

超写实真人电影级动作片，暴雨中古代日本城楼屋顶高速剑斗。以参考图为第0秒首帧，锁定两角色身份、面罩、头盔、发型、体型、服装、盔甲纹理、颜色与武器，全程禁止换脸、换装、脱面罩或换武器。
左：参考图女性绯红忍者，黑高马尾、红面罩、深红雕纹战衣、红黑分层护甲。右：参考图男性黑衣忍者，黑角形头盔、黑面罩、厚围巾、黑分层盔甲。双方各仅持一把完整日本刀。场景为暴雨古城屋顶：湿黑瓦、积水、冷蓝灰天、远处暖黄灯笼与飞檐。雨水、水花、甩水与湿衣动态需真实丰富，但大水花禁止撞击或遮挡镜头，禁止水滴黏镜；水花只向左右、人物身后及屋顶爆开。
首帧复现参考图腰部以上近景：女左男右，双刀中央成X形锁，立即动作、无静止。双方转腕加压，刀锋摩擦，火星与雨水向两侧及身后炸开，不喷镜头。摄影机crash push冲向接触点，随即高速pull out并顺时针急转约80度，转为24mm广角见全身与完整刀路，仅一次短促精准震动。
刀锁解后，男性连续斜劈、横切、反手斩、直刺，四击无缝、不停顿。女性以侧头近失、转肩、贴刀滑开、转髋卸力、低位滑步连续改变中线，一刀距面罩约3厘米掠过。摄影机如第三名战士冲入战局：低位贴瓦横移，冲至肩后再whip-pan捕捉下击，强烈景别变化，snap zoom in捕近失眼神，闪避完成即snap zoom out现全身，禁止缓慢平移或稳定中景。
女性借最后格挡切入内线，连续拨刀、压刃、滑步穿侧、回身斜斩、低位横切、旋身上撩，身体与刀势保持连续惯性，快而有力。男性以侧步、刀柄格挡、转腰贴刃化解并立即反切。摄影机贴男性肩后追踪，女性绕侧时故意跟丢2—3帧，随后猛烈whip-pan在另一侧重新捕捉，接反向约110度高速counter-orbit，刀锋近镜时急速后撤，镜头快、贴身、危险，但不可穿模。
男性双手重斩，女性侧移半步以刀锋贴其刀身外侧，借腕、肩、腰胯与滑步导力至侧方。攻击以100%速度接近，双刀将触时降至40%持续约0.3秒，清楚显示距离、眼神与力量方向；接触瞬间恢复100%，火星雨水向两侧炸开。随后两个极短hard cut构成不超0.6秒的speed repetition：同一撞击以侧面近景、20厘米低机位仰拍各重放一次——纯剪辑重放，不倒放不重置不产生分身。重放结束即回连续时间，女性旋身卸力，男性从她身侧冲过。
两人瞬间对冲：女性横斩被低位格开；男性反手斩被女性后仰近失躲开；女性贴地旋身扫刀，男性跃步跨过并落地反切。摄影机高速横穿两人侧面，急推急停、反向绕行，接触即push in，刀势展开即pull out。最后双刀强烈相撞，两人弹向屋顶两端。
Hard cut至女性三分之二侧面中广角全身镜头，完整见双脚、髋部、肩膀、手臂与力量传递。她左手将日本刀压低收于身侧，右手抽出一枚四角手里剑。她踩稳前脚，完成一次具重量惯性的270度全身旋转：脚掌蹬地、髋部先转、腰肩加速、右臂延迟甩出，旋转末端手腕爆发释放手里剑，不可站立挥手投掷。摄影机沿反方向高速counter-orbit产生强烈相对速度，释放瞬间whip-pan跟随飞镖；手里剑横向飞行，轨迹近乎平行画面，绝不朝镜头飞来或放大遮画面。
摄影机从侧面高速追踪手里剑，旋转轮廓与横向速度清晰可见。飞镖沿额头高度直奔黑衣武士头部。男性绝不挥刀格挡或劈开飞镖，日本刀始终保持身侧下方；飞镖将中眉心时，双脚抓地，头颈与上半身共同向后弯成流畅弧线完成极薄后仰闪避，飞镖从面罩上方约2厘米掠过。近失瞬间短暂降至35%速度约0.2秒清楚显示擦过轨迹，随即恢复高速飞出画面，摄影机同时push past其脸再猛烈whip-pan转向远处屋顶。
利用whip-pan形成hard cut，切至女性背后低位over-the-shoulder大全景：女性背部、红色高马尾与持刀手位于左侧近景，男性完整站在屋顶另一端右侧，相距约20米，中间为大片湿瓦负空间。两人低位警戒互相凝视，暴雨、湿发、衣摆与围巾仍剧烈运动。摄影机快速推向女性肩后后骤然减速，仅最后0.3秒完全稳定，不淡出。
全片除最后0.3秒外禁止稳定停留超过0.5秒。摄影机持续低位冲刺、近距离侧闪、快速counter-orbit、whip-pan、crash push、rapid pull-out与snap zoom，须产生强烈空间位移与视差，不可仅用数字变焦。允许轻微受控倾斜与专业手持震动，但空间轴线、角色方向及攻击轨迹须始终清楚。镜头快、凶猛、贴身，如亲自参战，但绝不随机乱转。
