A close up of a person in a underwear with a red hair

Yujiro Ko, Red-haired man, Stand in the gym, Decorated with the cringe of a demon figure. His muscular superiority and clear definition, is the focus of his high-intensity training. His red hair is wild and unruly, His white thong clings to his body. Light reflected from behind him, Highlight the intricate details of the tattoo. His bottom waves wave and soothe as his strength increases, His strength and thought are evident in his pose.
