Re these questions:
Scope: Actually my ideal is to ask this generally, but I think it's too big. I'm gonna limit asking to high school students, which is really my main target because I'm asking these re anime/manga which mainly feature high school students anyway. (For now, I'm just going to forego thinking about this for the anime/manga characters that are 20+.)
Question: Suppose student Ashanti Tanaka calls student Bidatz Mikoto as Mikoto-san. How relevant is the gender of Ashanti or Bidatz for if later Ashanti would later "upgrade" to call Bidatz as Bidatz-san or Mikoto-kun/chan (but not Bidatz-kun/chan)?
- Somehow, I suspect Japanese boys will upgrade calling other Japanese boys from last name-san to last name-kun but will upgrade calling Japanese girls from last name-san to 1st name-san. Idk. I know age factors in here, but my question here would then be: in any case of age, does gender ever matter?
Note 1: Also, hopefully this isn't an issue, but I hope we can assume for simplicity that 'kun' is used only for males and 'chan' is used only for females, even though of course I know it's not true. If not, then please explain why this assumption must be violated to really answer this.
Note 2: My issue is the 'upgrading' of last name-san to either 1st name-san or last name-whatever honorific, NOT why sometimes males/females can be called, resp, chan/kun. And also the honorific in 'last name-whatever honorific' is meant to be fixed/predetermined like as follows:
Case 1: Bidatz Mikoto is female. Then Ashanti would say either 'Bidatz-san' or 'Mikoto-chan'. Here, it's given that 'Mikoto-kun' isn't a choice. Also, Bidatz-kun and any other forms of address other are somehow ruled out. How relevant is the gender of Bidatz or Ashanti in Ashanti's decision between 'Bidatz-san' and 'Mikoto-chan' ?
Case 2: Bidatz Mikoto is male. Then Ashanti would say either 'Bidatz-san' or 'Mikoto-kun'. Here, it's given that 'Mikoto-chan' isn't a choice. Also, Bidatz-chan and any other forms of address are somehow ruled out. How relevant is the gender of Bidatz or Ashanti in Ashanti's decision between 'Bidatz-san' and 'Mikoto-kun' ?
Or idk is 'any other forms of address are somehow ruled out' a huge or weird assumption to make?
Some examples:
- In My Stepmom's Daughter Is My Ex, Yume Irido (formerly Yume Ayai) calls male friend Kogure Kawanami by last name Kawanami-kun but female friend Akatsuki Minami by 1st name Akatsuki-san. See.
Bidatz Mikoto
<-- Just to confirm, Bidatz is the given name and Mikoto is the family name, correct?
