Master manipulator Megumi Hino-Hano-chan is enraged by her failure to bring down timid Yaya Higuchi - and her alter ego, the confident and boisterous Nana. So Hano-chan decides to take the ultimate revenge. Using the singing contract that Yaya desperately wishes to and void as a means to her mean-spirited ends, Hano-chan makes Yaya an offer. She will rip it up . . . if Yaya agrees to play a little game with her. If Yaya can catch Hano-chan and steal the contract, Hano will cancel the agreement and return the application fee. Sounds simple, right? But there's a little hitch. Yaya must chase Hano while they're skydiving!
