"Visualize Shijin, a powerful Oni warrior, standing tall in a traditional Samurai armor, adorned with intricate designs of flames and ancient runes. His skin is a deep red with dark tattoos spiraling across his muscular arms. His face is fierce, with sharp horns curving upward from his forehead and glowing eyes, filled with determination and wisdom. In his hands, he wields a large katana, its blade shimmering with mystical energy. The armor gleams in a dark, ominous setting with distant lightning in the background, while his stance exudes strength and an unyielding warrior's spirit."
