The event of Kaguya and Yuzuru took place, right now Shido team won the singing competition, which of course got Miku upset, so she used her spirit powers to take control of everyone except for Izuna spirits, while fighting off Miku minions, Ellen had arrived, so Izuna told Shido to take of his girls, and found an opportunity to help them escape, and giving himself up to Ellen.
After Shido and the spirits were able to find shelter they received a surprised visit from Kurumi. Shido decided to put his faith in Kurumi and ask her for help in tracking down Izuna, to which Kurumi had agreed too.
Kurumi first took them to Miku house to help them discover more about her past and they did. They then went to Miku and Shido tried to convince her to join them in saving Izuna, unfortunately it didn't work out in their favor, so they escaped. Tenka and the rest of the girls were extremely worried about Izuna. They were able to locate where Izuna was being held at but, they were greeted by bandasnaches. Kurumi told Shido and the rest to head inside, while Kurumi and her clones chose to keep the robot busy, but some of Izuna spirits decided to back Kurumi up, for they wanted to release some pent up anger that they have been suppressing.
While the Kurumi and the spirits were keeping DEM soldiers occupied, Shido and the rest decided to infiltrate the company, but before they managed to get inside, Shido was reunited with his biological sister, Mana. Shido then learnt that Kotori was back to normal. Shido, Mukuro, Natsumi, Nia and Tohka continued with their infiltration, but then ran in Miku who had decided to help them rescue Izuna.
After they arrived they met Issac Westscott. Shido then was about try and break the sealed door, but then noticed that he had swapped place switched places with Izuna, when he looked back at Izuna he was horrified at what he saw and so were the girls.

Once Ellen had removed her sword from Izuna chest, he fell to the ground. Enraged what happened, the girls released a monstrous aura and started attacking Ellen in directions. Ellen wasn't able to keep up with movement for it was too fast for her, so she decided to retreat with Issac.
The girls wanted to follow them, but knew they had more important matters to attend to. Tenka fought inverse Tohka and was able to weaker her enough so that Shido could seal her.
After the whole situation had passed, Izuna was brought to Franxious for treatment, but to their surprise Izuna wound was already healed, causing Izuna to wake up. Izuna explained that he has instant regeneration abilities, which helped asses Reine in her understanding. After he was checked out he was instantly swarmed by his harem, who all cried their eyes out seeing that their prince was alive and well.
A month passed and Natsumi was brought into the Shido harem. Izuna was a bit protective of kid Natsumi, since in his world kid Natsumi is his little sister. A week passed Origami had tried to kill the spirits, thankful Izuna and his girls were able to intervene.
Once Origami left, Izuna was then met by Kurumi who told him what had happened. That Origami had ask Kurumi to send her back to the day her parents were killed. Izuna told Shido what had occurred, Shido then asked Izuna if he could take him to Kurumi, which he did. After they found Kurumi, Shido asked Kurumi to send him to the past to help save Origami, which he had accomplished.
Izuna and the other still had their memories of the previous world. They had noticed that Origami had changed, but for some reason Izuna felt another presence inside the new Origami, Izuna then used his sharingan and found out that there was another Origami inside the new Origami. (personality disorder) Izuna realized that the previous origami must've linked or merge with her new self, which had created two separate beings.
After it was confirmed, Izuna explained it to his girls and Shido. In the end Shido managed to seal her powers as well, but it turned out that Shido had absorbed too much of his girls spirit powers, which made his body overheat. Luckily Izuna and his girls weren't involved, so they just watched what happened and in the end they managed to save Shido.
