Memory: Back outdoors, the girls discover a strange place featuring tall black slabs filled with drawers. Yuuri finds a mysterious device and other seemingly meaningless objects inside them. Chito deduces that the drawers are graves containing the belongings of those who have died so they would be remembered.
Spiral: Afterwards, the girls ascend a spiralling path up another tower in their Kettenkrad. They are forced to take an outside path which dangerously collapses behind them, but they manage to reach the summit.
Moonlight: Exploring the top of the tower, the girls find some bottles of beer and spend the night getting drunk under the moonlight.
