Volume 22 - Young Man Period - Organization Chapter
The final stages of the multiverse teleportation circle are being made as it was completed and she had Rudeus and Perugius test the device, With Perugius operating and controlling it and Rudeus supplying the magic power. After teleporting many objects and living beings much larger than her into her original world, the circle was ready to send her back to her home world. She decided to use the bath in Rudeus's home and stay the night. While She and Rudeus were drinking and she was wondering how much time may have passed since she was in this world, Rudeus told her that ten years have passed since the traffic accident and time may not have changed much in the other world. After hearing that, she figured out Rudeus's identity in the previous world. She was asked to keep it a secret since Rudeus was ashamed of who he was in that world and gave her a letter to deliver to his siblings from that world.

The final day came and they used the multiverse teleportation circle to send her back to her original world, but then a strange black colored light appeared and the attempt to send her back failed. The magic circle failed as if the power was absorbed somewhere else. Perugius was mad at Rudeus and started blaming Rudeus for the failure of the device, thinking Rudeus cut off his power. Rudeus then stated that he didn't cut off his power and in fact increased his power. After the confusion, they were able to determine that if the mana supply were cut off, the magic circle would have lost its light. Mana was definitely used, but it seems as if something was tampering with the process. They found a crack in the circle that should not have broken. Nanahoshi left the room and Rudeus went after her. After the failure at using the multiverse teleportation circle due to some type of interference, she developed a hypothesis that her friend, Shinohara Akihito, who likely teleported into the world in the future and saved a Miko that had the power to rewind an object's time. Nanahoshi hypothesized that he likely also met Orsted and created a device that would amplify the Miko's power. The reason why she was summoned to the world was to create the multiverse teleportation device and the reason she is unable to return now is because her future self is supposed to return to her world in the future with her friend. She then decided to have her time stopped so that she may live long enough to the future 50 to 80 years from now and use the teleportation to allow her friend to go back home as well.

Mushoku Tensei Sequel
Nanahoshi's fate is one of the major story threats that remained unresolved by the end of Mushoku Tensei, continuing to be kept in suspended animation by Perugius to await Akihito's arrival so she might go back to Earth. Because of this, she is likely to once again play a major role in the planned sequel series.
