However, when Misumi Mikoto found Chen Yu, hoping to receive help from her teacher in constructing her own Necromantic Space, Chen Yu did not immediately choose to help her. Instead, he tested his apprentice's knowledge on the construction of Necromantic Spaces.
"How many of the fourteen structural forms used to stabilize space structures can you recall? What will you use to anchor after searching for Space Fragments? Have you learned how to draw all the requisite Magic Circles for the ceremony?" Chen Yu, recalling the preparations he had made constructing his own Necromantic Space and with a hint of nostalgia, asked Misumi Mikoto.
Hearing Chen Yu's questions, Misumi Mikoto nervously replied, "I've memorized all the necessary Magic Circles for the ceremony. As for the fourteen structural forms to stabilize space structures, I can remember twelve right now. But I haven't figured out how to anchor them yet, since I lack the materials to do so."
