Incident
A few days after returning from the Great Tomb of Nazarick, Shido Istuka and his friends slowly returned to their daily lives in Tengu City. While walking through the streets, Tohka Yatogami is running her mouth on her experience in Nazarick and its wonderful facilities, especially its kinako bread. Shido listening to his classmate's banter for the tenth time reminds her that she had already told them this. Tohka though claims that it was in fact for Yoshino Himekawa and Yoshinon's benefit. Yoshino does not remind the repetitive story as it sounds to her that Nazraick was a wonderful place to be. The puppet Yoshinon worries about the numerous monsters that live there, however Origami Tobiichi assures her that the denizens of Nazarick despite their gruesome appearances were unconditionally kind and trustworthy, unlike the organization, DEM.

Origami is more interested in being alone without any interruptions with Shido, though the young man tries to avoid her advances. Tohka seeing her rival making moves toward Shido, laments that the Eight-Edge Assassins are not present to get her away from him. Yoshinon seeing Origami and Shido, urges Yoshino to not to lose pace as well. Kotori Itsuka returning home from school joins them, humored at the noisy harem fighting over her step-brother. She reminds Shido that they need to head to the underground facility, but then notices Yoshino. Yoshinon who explains their presence that they were going for medical check-up and met with Shido and the others en-route. Finding that acceptable, Kotori breaks up the tug of war with Shido between Tohka and Origami, though the two promise that it's not over.

Unknown to the group, Kurumi Tokisaki is watching them atop a building. A siren soon rings out and several passersby and student hurry to head to take shelter from the approaching spacequake. Kotori realizes that the spacequake is happening near them, and a Crack emerges and begin sucking them into its mouth. Tohka quickly goes into Spirit form and stabs her sword into the street and tells her friends to hold onto her. The grip on Tohka and the embedded sword doesn't seem to be enough to keep Shido and his friends from being pulled into the Crack. Several gunshots go out and the group find that the movement of their bodies is slowing down. Kurumi reveals herself to have used her power to slow time around the anomaly with her [Second Bullet Bet]. She urges the women to combine forces to break from the gravitational force of the Crack, as there is no certainty that if they go into the Crack it will take them to Nazarick. However a figure from within the anomaly uses [First Bullet Aleph] and causes time around the Crack to accelerate and resume pulling the teenagers in. Everyone is sucked in leaving no trace of them.

In the Throne Room of the Great Tomb of Nazarick, Momonga and Demiurge are conducting another summoning experiment using Chaos Stones to gain more information. Their experiment leads to the Crack in the room activating and spitting out Shido and company on the ground in a heap. Shido getting hs bearings sees a nearby Death Knight on standby and is relieved to learn that they are in Nazarick once again. Greeting Momonga warmly the young man is happy to see an old friend. Momonga is shocked to see Shido again but first makes Shido confirm his identity as Shido Itsuka who visited Nazarick in the past. When Shido's identity is confirmed, Momonga and Demiurge see that they have a first time situation where individuals from another world have been resummoned. The experiment though having unexpected results, Momonga is glad to see his friends from another world as it has been a long time. That is not the case as both Momonga and Demiurge are shocked to learned that only a week has passed in Shido's world since they last saw each other.
