クリッププロンプト

■クリップ1

Continue the existing scene from the previous generated H3 clip with no cut, reset, or re-establishment. The incoming protected H3 audiovisual latent prefix is authoritative for current pose, motion, camera trajectory, facial state, lighting, environment, object state, voice, ambience, and timing. Connected reference images are optional; use them only to preserve stable subject identity and appearance beneath that incoming state.

Do not continue, extend, imitate, or infer any human voice or vocalization from the incoming audio context. The character remains completely silent throughout this continuation. No speech, dialogue, chatter, whispering, mumbling, babbling, singing, or intelligible words in any language.

[Shot 1 | 0:00.0-0:02.0]
The Oni Princess slowly extends her right hand underwater. Her expressionless face maintains an eerie beauty from the beginning to the end of the video.

[Shot 2 | 0:02.0-0:08.4]
The Oni Princess also extends her left hand underwater, picking up a white and cold human skull with both hands. The skull drips with countless water droplets, causing ripples on the surface.
S1: [Japanese] 我の同胞よ。……秩序の礎となれ。

Continue the exact motion and existing non-vocal environmental sound already in progress, then develop the next action naturally. Preserve the silence: do not add or continue any human voice or speech-like vocalization. [DESCRIBE WHAT HAPPENS NEXT; DO NOT RESTART FROM REST.]

The Oni Princess raises the skull to her chest and sits quietly on it. Around her, water ripples and faint red phosphorescence can be seen.
