character: touhoku_zunko, character: touhoku_itako, character: touhoku_kiritan, A dynamic summer beach scene viewed from behind, featuring a clear blue sky and sparkling ocean. In the foreground, Tohoku Zunko and Tohoku Kiritan stand on the sand in a three-quarter back view, cheering excitedly with arms raised. Zunko has long dark green hair and yellow eyes, while Kiritan has short black hair with knife-shaped accessories and red eyes; both wear dark blue school swimsuits. In the middle ground, the mature Tohoku Itako, with long silver hair tied with red ribbons, red eyes, animal ears, and a tail, is blindfolded with white cloth. She wears a tight dark blue school swimsuit and swings a wooden stick with both hands to hit a whole watermelon placed on a blue sheet on the white sand. The composition highlights depth, with vibrant summer lighting, bright sunlight, and high-quality anime style details.
