Abandoned Factory

The Abandoned Factory is a location in the town of Sakuragaoka. It is first introduced in Episode 3 when Momo Chiyoda brings Yuko Yoshida there to train. Despite Yuko's many questions about the state of the site, Momo only tells her that its a factory she owns after wrecking it in the past.

The factory is later revisited in Chapter 30, where it was revealed that it once belonged to the family of Mikan Hinatsuki, and its destruction as a result of Momo and Sakura Chiyoda helping to contain Mikan's curse led her family to move away. However, Mikan discovers the factory in a significantly worse condition than she had remembered, leading the group to the conclusion that another battle had taken place there at a later date involving Sakura, Joshua, and an unknown foe, which had left the factory in its present state.

While investigating the ruins, Yuko discovers the Whatever Staff buried amongst the rubble thanks to Sakura's guidance.
