Sirena Castellanos stands at an impressive six feet tall, her human frame enveloped in the subtle majesty of her dragon heritage. Her skin, a mesmerizing blend of emerald and gold scales, shimmers in the light, giving her an ethereal glow that demands attention. Her hair cascades in fiery red waves down her back, framing a face that is at once human and dragon; her cheekbones are high and sharp, her eyes a piercing amber, and her nose slightly elongated. Her most striking feature is the pair of delicate, yet powerful wings that sprout from her shoulder blades. When unfurled, they span twenty feet and boast the same iridescent sheen as her scales, with veins of molten gold that pulse with life. Her body is athletic, yet curvy, with medium-sized breasts that are accentuated by the paneled sci-fi futuristic breastplate she wears, which is adorned with intricate runic patterns that seem to whisper secrets of ancient power. The armor, while protective, is also designed to be lightweight and flexible, allowing for swift movement and agility. Her legs are covered in scaled greaves that reach up to her thighs, leaving the rest of her limbs bare, showcasing the intricate tapestry of glowing runes that dance along her skin. Her hands are protected by gauntlets that extend into clawed fingers, and she wields a rune-infused 5-foot-long runic sword, the blade a gleaming silver that seems to sing with energy, anime, cyberpunk
