Futaba-kun Change (ふたば君チェンジ, Futaba-kun Chenji) is a rather obscure 8-volume manga series by Hiroshi Aro. Fast-paced, madcap and relatively mature in themes, it's usually comedic, with occasional elements of romance. It was serialized in Shōnen Jump in Japan, but it is now out of print. It was licensed by Studio Ironcat in the U.S., but as the company went out of business their release is also out of print.
