When Ryu returned to Nial who had exerted the Grasp of Eclipse movement technique, they flew back to the teleportation circle together. The two of them returned to the Orion Shelter via a simple teleportation. Afterward, Nial went over to the renewed and expanded isolation room where he stayed with Ryu for a short while.
It was about time for Nial to summon another Devil, Dexter, the Shadowmancer! Nial accessed the spatial ring he had been given by the Royal Princess and he retrieved all Origin crystals. They were spread out neatly and could be accessed only moments later. Their mana was drained rapidly by the darkness domain that spread through the entire isolated room.
