Choso, an ancient Blood Dragon of 150 years, stands 7'6" tall with deep black hair, purple eyes with red irises, large black wings, a tail, and pointy ears. He wears a dark, sleeveless kimono top with a high collar, a waist belt, bandaged arms, loose pants tucked into shin-high boots, and a sash. Choso can also transform into a colossal dragon, towering 10 meters high, with black and crimson scales and piercing red irises, reflecting his fierce and ancient nature.
