Where'd the Ma-Pet Pet Go? Pri!

One day, Ringo wakes up and notices her Ma-Pet, Sei, is gone. Ringo talks with Leila and Natsuki who say that Dai and Ryoku have been gone since morning too. The girls walk around the town searching for the Ma-Pets, but are unable to find them. They think back and wonder if they had done something wrong. Sei was crushed when Ringo rolled over in her sleep, Dai's crackers were taken away by Leila, and Ryoku was thrown out of the room by Natsuki for being fussy... so many possibilities come to mind. Worried, the girls go to ask Chris. Meanwhile, the Ma-Pets are walking around Hanasaki in their Halloween costume. It seems the Ma-Pets have some reason for doing this...
