Arc 22Lilith’s Hidden Past
After Lilith rewrote the world so that she was a beloved teacher, Kirishima Ai and Takanashi Shiori investigated her plans and uncovered her ties to Silver Feather and the origin of her rebellion. As R'lyeh prepared for war, Fate Kite and Dark Kite began a duel at school, which ended with Dark Kite removing her Nightmare Dragon crystal.

- Shiori and Ai discovered that R'lyeh's nobles were preparing a holy war against Lilith and went to R'lyeh to search for clues.
- Shiori heard Roland Eldritch explain the origins of the Demon Kings and the history behind Lilith's rebellion, while Ai explored Lilith's former home.
- Ai recovered memories of Silver Feather, Lilith's adopted daughter who died young, and learned from Roland that Lilith had become the Overlord while trying to resurrect the dead and end suffering.
- Ai asked Roland about Lilith's motives, then planned to return to Maple Plain City and find her companions.
- Fate Kite and Dark Kite fought at Kaedehara High School, with Dark Kite overpowering Fate Kite through her armor, dark energy, and Phantom Swords.
- Dark Kite stopped attacking and removed her Nightmare Dragon crystal as Fate Kite asked why she had not demanded surrender.
