Although he has surmounted many obstacles, Shidou Itsuka's assignment with Ratatoskr remains unfinished. Deviating from his usual schedule, Shidou meets a hungry woman sprawled on the pavement and ends up aiding her. When they reach her flat, she identifies herself as Nia Honjou—a well‑known manga illustrator who writes under a pseudonym. Straightaway, Nia discloses that she is also a Spirit and knows about Shidou's covert mission. Curious to experience his magnetism directly, Nia dares Shidou to impress her on a date. While attempting to secure the chance to bind her powers, Shidou uncovers more about Nia and her connection to Deus Ex Machina Industries, where secrets are traded like currency and power struggles echo through its halls, for the stakes are high and the future hangs in balance ever.
