ubaru's save point is moved (it seems killing the whale was an objective).
Now Subaru heads the allies to face Betelgeuse and the Cult of the Witch.
They lose several times, and everyone killed, but each time Subaru learns more about the Bishop and plans his tactics. The insane Bishop has the power to manifest invisible "Hands of God" that can kill anyone without them ever seeing them.
After many bloody battles, Subaru and his allies is victorious and Betelgeuse is killed.
It's the best possible outcome, or so it seemed.
Subaru wins back the trust of Emilia, but learns a shocking truth... she doesn't remember who Rem is.
He rushes to go see Rem, to find her comatose and no one remembering her.
Rem and Cruche has been attacked by Bishop of Gluttony. Rem was eaten and "erased" from the world, whereas Cruche's own memory was lost (others remember her fine).
Not even Ram, Rem's own sister, remembers who she is.
