• Scathach confirmed Kanon’s name while Himeragi Yukina watched Su Yang with suspicion.

• Scathach agreed that Kanon seemed destined to transcend the world, and Su Yang explained that she could evolve into an angel and ascend to a Higher Plane.

• Tsukishima Rin and Shinomya Rin offered Su Yang gifts and confessed, and he told them to talk to him again when they were older.
• Nangong Nayue confronted the girls, and Tsukishima Rin pulled her friend away after Nayue struck them with her fan for calling her “Natsuki-chan.”
• An explosion triggered the Demon Special Zone’s alarm, and Su Yang and Nangong Nayue looked toward the disturbance.
• Himeragi Yukina evaded Blazing Hoof’s attacks and used Yukina Shirokami to destroy the Familiar, leaving its vampire summoner at her mercy.
• Su Yang deduced that the demons had provoked Yukina before one of them summoned Blazing Hoof.

Su Yang explained that Yukina Shirokami would eventually send Himeragi Yukina to another world because she was a Descendant of Methuselah, then offered to devour the Divine Energy it produced. The solution gave Yukina hope, though Su Yang warned that she might not accept what it required.

• Su Yang told Himeragi Yukina that humans had no known experience killing True Ancestors and explained the spear’s danger.
• Su Yang revealed that the Lion King Organization had raised Yukina as a Descendant of Methuselah suited to wield Yukina Shirokami, which converted her Spiritual Power into Divine Energy and would eventually make her disappear from this world.

• Su Yang said he could solve the problem by devouring her Divine Energy if she came to him regularly.
• Yukina eagerly agreed to overcome any difficulty, and Su Yang asked whether she was sure she could accept the remaining problem.

Su Yang watched Asagi Aiba revive on Kagurajima Island and gave her clothes after her own were destroyed. He discovered two new sign-in plots involving making Asagi his witch and gaining control of the Power of Holy Annihilation.

• Su Yang explained that Kagurajima Island's protection made Asagi Aiba impossible to kill while she remained there.
