Pandora no Yume

During a summer training camp, members of the arts club explore the basement of a European-style school building and find a nursing robot named Suu, non-functional due to a drained battery. Protagonist Hirano Yuito revives her, and the female-appearing robot recognizes him as her new master. On the final day, after an enjoyable week, an earthquake strikes. Yuito dismisses it, but suddenly everyone is warped back a week in time, their memories intact. As the loop repeats, Suu begins to recall faint traces of the week and surprisingly shows signs of humanity. A tale of time loops, robotic awakening, and summer mystery.
