Two ninjas train in a dojo with red and blue energy

Original prompt

Create an 8-second animated sequence featuring 2 mysterious Shinobi ninjas sparing using ninjatō swords in a traditional Shinobi dojo. The dojo should have a minimalist design with wooden floors, tatami mats, and wooden walls, maintaining an open structure to allow for extensive movement and sparring activities. The ninja characters are dressed in traditional attire with a hood.

One ninja should be surrounded by swirling red energy trails that emanate from his body as he performs fluid, martial arts movements. The energy effects should pulse and flow, emphasizing their power and agility.

The second ninja should be surrounded by swirling blue energy trails that emanate from his body as he performs fluid, martial arts movements. The energy effects should pulse and flow, emphasizing their power and agility.

In the background, include traditional training weapons such as shuriken, kunai, and possibly a kyoketsu-shoge, mounted on the walls or placed around the dojo. Add scrolls and a few calligraphy banners with Japanese characters, reflecting themes of stealth, endurance, and martial prowess, hanging on the wooden walls. The overall color palette should be dominated by natural wood tones, with the glowing red energy providing a stark contrast. Subtle smoke effects at the base of the dojo can enhance the mystical atmosphere, while the open design of the dojo ensures the focus remains on the ninja's dynamic movements and the glowing energy trails.
