Despite the many challenges he has overcome thus far, Shidou Itsuka's mission with Ratatoskr is far from complete. Breaking from his usual routine, Shidou comes across a starving woman lying on the street and ends up helping her. Once the two reach her apartment, the woman introduces herself as Nia Honjou—a popular manga artist working under a pen name. However, getting straight to the point, Nia reveals that she is also a Spirit and knows about Shidou's secret operations. Interested in witnessing his charisma firsthand, Nia challenges Shidou to win her over on a date. As he seeks an opportunity to seal her powers, Shidou learns more about Nia and her history with Deus Ex Machina Industries, a name he is all too familiar with.
