How clumsy you are, Miss Ueno.

As president of her middle school’s science club, Ueno pairs sharp intellect with a talent for outlandish invention—whipping up gadgets that can purify any liquid into drinkable water, erase even the worst odors, or produce dark matter for cover. Yet her real purpose isn’t scientific progress; it’s the one mystery she can’t solve with an equation: love.

Ueno’s crush on her laid-back clubmate Tanaka leaves her tongue-tied, while his complete lack of awareness keeps everything at a standstill. Convinced that a little embarrassment will finally make him notice, she stages a string of risqué “experiments” using her creations, backed by the deadpan support of her classmate and steadfast accomplice, Yamashita.
