Necromancer Arc
Esther Rosenthal along with Hitokawa Hasami (Huotou) is performed a ritual with her Emperor Shun's Blade as a countermeasure against the Rosenthals' artificial souls.

 * The location where Esther performed a ritual with her blade is different - in the open near a tree and somewhere were Hirumi apparently was before, rather than in a closed building with no apparent relation to their past.
