Ep. 10: Alice revela el bucle temporal de la Clase 3-4 a Ai y sus compañeros en Ostia.

10

A flashback shows the city of Ostia with an enormous Ferris wheel, and before killing his classmates, Alice explains that they are in a closed space where the world resets itself to default values as if destruction and change never happened. In the outside world, arriving at a desolated Ostia, Alice leads Ai, Julie, Scar, and Celica to the sealed Class 3-4, accessed through a school building. He explained they will not be able to leave until the seal over the city is broken, but Ai still chooses to help, and Julie and Scar state they will follow her wherever she goes. They are welcomed by the people of Ostia in a out-of-sync winter, and walking towards Alice's home they are greeted by Dee, who now has a physical form. Settling at their new home, they notice that the world is fourteen years ago in the past and question Alice, but he is reluctant to answer just yet. Another flashback shows the first time Alice and Dee left Ostia, and Dee is shocked to find herself as ghost. Later, Ai transfers into Class 3-4 and meet the classmates of Alice and Dee. Dee asks Ai if she has interest in any school activates, saying she may come to like staying in Ostia. Ai begins to realize that the world of Class 3-4 was created by a wish, which Alice confirms. That night, Alice finally explains Ostia is trapped in a temporal loop that resets every July 28th, and thus far Alice has brought a total of 35,695 living people into Ostia in order to shake up the world. He also reveals that Dee is probably preventing him from solving the temporal loop for unknown reason. The final scene is a flashback of Dee falling out a window. (Source: Wikipedia)
