"Re-life"

Satella couldn't take it anymore... Seeing her beloved suffer so much just because she had summoned him to that world.

The witch of envy then sent Subaru back to his world... When he woke up, he was told it had all been a dream and that he had been in a coma for a year. He then resumed his life as a student with the support of his parents.

But in the other world, his friends were devastated by his disappearance... Emilia simply couldn't accept that her beloved knight had vanished into thin air.

And so she spent two years searching for him relentlessly along with the others, even after she had managed to become queen of Lugunica.

Two years later... Then one day, Reinhard discovered a kind of portal that said it could take them wherever they wanted... He, along with Emilia, Julius, Felt, Ram, Garfiel, and Otto... wished to be taken to where Subaru was, and the portal agreed, saying it would send them to a place near where he was.

And then... They simply fainted. When they woke up, they were in the middle of a busy street, in a place they had never seen before... With buildings, signs, and various things they had never seen before.

(You decide what happens next, and what happened to Subaru during those two years.)
