Chapter Summaries

Saigō prepared to bring Gensokyo’s youkai under his protection and extracted the Takamagahara Pantheon’s worldview from Ama-no-Murakumo-no-Tsurugi. In Makima’s apartment, he reduced the Control Devil to an obedient dog, while the War Devil and Asa Mikata struggled with their feelings and impulses around him.
