Even though Michael had only been in the Origin Expanse for a few hours, he had yet to take a proper look at his territory. The daily reports were also waiting for him to extract.
Despite that, Michael chose to leave the Origin Expanse. He had to return to the Nest and ask something. The Runic Gate manifested before Michael, and he disappeared again.
Back in the Nest, Michael rushed out of the training hall, searching for Evee. Fortunately, it didn't take long to find Eren's daughter. She was in a massive room, working on something. Michael unleashed Cosmic Stride to appear near her. He cleared his throat and approached Evee, ignoring the mountains of books and the bunch of people in the room.
