Wanting to leave her name in history, Phantom Thief Reinya tries to come up with a memorable special ability. Inspired by the book "How to be a Ninja", she begins training in ninja techniques. However, the electric fan of her "Hidden Leaf Technique" leaves her in a mess, and she nearly drowns when a dragonfly perches the straw of her "Hidden Water Technique." Realizing the plastic straw is too thin for the "Hidden Water Technique," she replaces it with a bamboo tube just as a sparrow approaches.
