Background
Spirit. A special disaster-designated life form that appeared through the Throne of Kings. There are two options. First, destroy the spirits with force. However, because of their high fighting and unknown power, there is a great risk. And the otheris to date the spirits to delay.

Incident
One day after school, Shido Istuka heads to a multi-tenant building in Tengu City, leading to a secret entrance to an underground facility of Ratatoskr. He is later joined by his classmates, Kotori Itsuka, Tohka Yatogami and Origami Tobiichi. They are talking about the upcoming physical examinations, chatting about how they can avoid it, while being secretly watched by Kurumi Tokisaki. A spacequake soon occurs, signalling the group that trouble will occur. Just as they are about to make preparations for battle, a crack in reality appears behind Kotori, sucking her into the void, followed by the rest of her friends. Kurumi watching from afar it also dragged into its grip leaving behind an empty street.

In the Great Tomb of Nazarick, Momonga and Demiurge are regularly conducting summoning experiments with the Rift in the Throne Room. As always a troop of undead guard the periphery of the phenomena. The Rift flares for a bit, spitting out Shido and his companions. While the students get their bearings, Shido fails to notice the Death Knight looming behind him as he gets up. Origami believing Shido is in danger immediately goes into her Spirit Form and attacks the undead. Kitori tries to restrain her friend in order to get a lay of the situation. However the Skeleton Warriors surrounding the Rift march in a aggressive manner, giving Origami the justification to attack. She is soon followed by Tohka who also transforms into her Spirit Form.
