Again, I meant the person in the background in the last panel, not Utsushiro Fumi who Rentarou is talking to, that's just there for context. Naddy has never mentioned Morikita.
I didn't think people would think I'm so out of my mind that I'm claiming this person who looks nothing like Morikita, who Rentarou is directly talking to, and who has an entirely different name could possibly be the same as the one introduced in this chapter.
