Kiyo, Zatch, and Shion chase after Grisor but fail in retrieving the mirror from him in time. Hakase uses the mirror and causes Grisor to grow into a monstrous being which increases his spell power by a hundred fold. They engage in battle but are unable to cause damage to Grisor. When Grisor aims a spell towards Shion, Nya pushes her out of the way but Nya's book is burnt in the process. Shion holds onto Nya as he disappears from her arms. Grisor then traps Kiyo, Zatch, and Shion on a patch of land by surrounding the area with magma from underground.
