Design a highly detailed and realistic full-body image of a character named Unas, with dark hair and an intense gaze. He is wearing a contemporary, blue jacket with rolled-up sleeves and golden accents, over a full-length overcoat adorned with pale blue patterns. There should be a keychain with the label 'UNAS' attached to the skirt. Behind Unas, an ethereal, semi-transparent blue figure with a serene expression embraces them from behind, like a guardian spirit. The background should suggest a calm and modern spiritual space with soft lighting and tranquil ambiance.
