This is in reference to a recent event held at Kadokawa Publishing's offices, at which Minori Chihara (Nagato) and Tomokazu Sugita (Kyon) were in attendance.
They were previewing some various upcoming projects, and Minori tripped over some of her words introducing one of them, so Tomokazu made the off-the-cuff remark "Nagato, are you okay with that introduction?" to which she replied "......I'm fine, it's not a problem."
Additionally, the exchange "Are you okay with that (blank)?" and "I'm fine, it's no problem" is a reference to an exchange between Lucifel and Enoch in the game El Shaddai: Ascension of the Metatron.
