Ep. 12: Dee confronts the truth of Alice's death while Class 3-4 prepares to leave their world.

12

Dee overhears Alice's resolve to free Class 3-4 and decides to reset the world by destroying the old one. She kills a male student to shock the class into remembering that day's incident, causing the environment to drastically reset as she attempts to jump from a window again. Meanwhile, Julie and Scar witness a fog-wave threatening Ostia. Dee falls, but an epiphany strikes her: Alice actually died that day. Alice grabs her, and Ai with Class 3-4 pulls them to safety. As the fog retreats, Alice remembers dying while saving Dee and convinces the students to depart for the outside world. He reveals he was buried by a gravekeeper and urges Ai to go as God's observer. In the epilogue, everyone has evacuated. Ai stands before Alice's grave, where he appears and asks why she saved him by wishing for his continued existence, and she smiles.
