A fierce kaeru-ma monster with sharp fangs, glowing eye, and clawed limbs emerges from Hokusai-inspired ocean waves beneath a deep red rising sun. Hand-drawn sumi-e ink linework with vintage paper texture. Inspired by classic Japanese folklore, edo-period monster scrolls, and ukiyo-e yokai prints. The frog yokai is a creature from ancient Japanese mythology associated with water, transformation, and the supernatural realm.
