On his way back from the grocery story, Subaru Natsuki is suddenly summoned to another world. In front of his shining eyes there is a new, fantasy land. There is no beautiful girl summing him, though. In the end, Subaru gets frustrated not seeing anybody around him.

Subaru is sure that he is killed the past few times. However, when he regains consciousness, he finds himself back at the place he first arrived.

Shortly after Satella arrives, Elsa appears and begins to attack them. Puck helps them fight against Elsa and gains the upper hand.

Badly injured from his previous fight, Subaru wakes up and finds out that he is currently inside Roswaal's mansion.

Instead of the date he was anticipating, Subaru wakes up and finds himself back to the time when he first came to the mansion.

Subaru begins his first day for the third time inside Roswaal's mansion. He decides to figure out how he was killed the previous two times.
