On the Angels' day off, Milfeulle wants everyone to spend the day having fun at the onsen. Everyone else, though, has their own idea of fun and they all go their separate ways. Ranpha finds men, Forte finds weapons, Mint finds something worth discovering, and Vanilla rock climbs. Depressed, Milfeulle tries to find ways of amusing herself without her friends, wishing all the while that they would come back. As Milfeulle almost runs out of hope, Vanilla accidentally uncovers a hidden hot springs, spilling water out and washing her and the other Angels back down to Milfeulle. Milfeulle enjoys the rest of the day off while the other Angels have been knocked out by the water.
