Yuuko, Mio, Mai, and Nano are all sitting around at the park. Yuuko was talking to Mio, Mai was carving a Maitreya statuette, and Nano was thinking about something to herself. It's midday, and the sun is still shining brightly.

Yuuko: "We could try making a card house!"

Mio: "But then we'd have to move inside. And remember how stressful that was last time?"
