Now that Keiichi and the goddess in his life are the hot item on campus, they find themselves constantly putting out fires! First, to raise money for the N.I.T. Motor Club, they get roped into posing nude together for a life drawing class - even though, as Keiichi's sister correctly guesses, they haven't even kissed yet! Then his "buddies" in the club stake Bell-chan as the wager in a funnybike race - but Keiichi has trouble seeing the humor when it starts coming apart at high speed! After all this, Keiichi just wants to relax and watch some home videos… except this video introduces (literally) a second goddess into his life - Belldandy's "sophisticated" older sister, Urd!.
