As the leader of her middle school's science club, it is only natural for Ueno to be an exceptional inventor. Her devices have the ability to transform any liquid into drinkable water, eliminate unpleasant odors, and even generate dark matter as a means of concealment. However, these creations are not driven by a desire to advance humanity. Instead, Ueno is motivated by love, which she finds difficult to comprehend fully.
Ueno has fallen deeply in love with Tanaka, her nonchalant club member. Despite being too nervous to express her feelings and Tanakas obliviousness to her affection, her romantic life remains stagnant. In Uenos mind, if she could expose Tanaka to suggestive situations, he would surely become agitated and realize his love for her. With the help of Yamashita, Ueno employs her inventions in a lewd manner in an attempt to make Tanaka understand her feelings.
