REMOW describes the new arc:
Having survived the fierce battles in Kyoto and Nerima, Shiki and his fellow students at Rasetsu Academy are steadily growing stronger. But Yaoroshi rejects Mudano's lessons on the importance of friendship. Drawn to Oni Brigade General Hayate Todoroki's call for “the total eradication of the Momotaro,” he leaves the academy.
When Shiki realizes that the Oni Brigade's creed makes even noncombatants targets for slaughter, he sets out after Yaoroshi with Mudano and the other students.
Their destination is Nikko, where Kegon Falls stopped flowing some time ago, and a massive research facility has since been built. Within its walls, horrific experiments are underway...
