In Kaguya-sama Chapter 52 / S02E02, there's a character named Moeha Fujiwara (the imouto of a main character Chika Fujiwara) who talks about Kei Shirogane (the imouto of the male protagonist Miyuki Shirogane) to Kaguya Shinomiya (the female protagonist and title character) as follows:
See 0:11 - 0:18 here.
Question 1: I could be missing something, but does Moeha actually NOT use keigo with Kaguya when talking about Kei and then later when talking directly to Kaguya uses keigo?
- Later in the manga:
Question 2: If so, then what's up with this: Do you like not really use keigo or something when 'narrating' or describing someone else to someone you'd normally use keigo with? (Well if not, then maybe it's a hint? Lol.) If not, then, what, Moeha is indeed using keigo throughout?
Note 1: Not sure if relevant, but Yuta says 3:34 here: In that school everybody pretty much uses keigo with everybody else.
Note 2: In S03E10, Kaguya and Moeha meet again, and they use keigo with each other. Actually here's the full compilation:
Afaik, Moeha Fujiwara and Kaguya Shinomiya have interacted on-screen only in S02E02 and S03E10. Their conversations are broken down into:
S02E02 at the start of their outing with Chika and Kei Shirogane when Moeha talks about Kei to Kaguya (Moeha: Kei is cute, and I want to lock up Kei in a dungeon.) - Not keigo. - See 0:11 to 0:25 here.
S02E02 briefly right after (1) above when Moeha talks (about Kaguya) to Kaguya. (Moeha: You're at the top of my list of things I love to the point that I'd want to eat you.) - Keigo. - See 0:32 to 0:40 here. (I guess 0:25-0:32 isn't keigo, but I guess I won't count it for the same reason as (3) below.)
S02E02 at the end of their outing when Moeha invites Kaguya for a group hug - Either not keigo or N/A since just 1 line. - See 1:25 to 1:30 here.
S03E10 when Moeha talks about Miyuki to Kaguya - Keigo. - See 2:20 to 3:01 here.
Summary: The only time Moeha doesn't talk keigo to Kaguya is when Moeha is talking about Kei.
