Oyuki plans to make a business out of flying sherbets, little bird creatures capable of quickly reproducing sherbet cones from their beaks. Ran convinces her to let her borrow one so she can open a sherbet stand on Earth to make some money, but the combination of being overworked and under the heat drives the sherbet to become cranky and escape. For fear of Oyuki’s retribution, Ran must catch the pesky bird that an angry Benten is pursuing for trashing her bike while going on a rampage shooting cones all over Tomobiki.
