One day, while strolling, Leto came across an animal resembling a rabbit. When he peered into the well indicated by the rabbit, he jumped headfirst into the bottom of the hole. There, he found himself in front of a castle he had never seen before. The protagonist was taken aback when a beautiful woman with large breasts suddenly approached him, but then a gallant helping hand came to his rescue.
