I didn’t think it was a big deal. However, I was maily wondering why I heard that some characters who were younger (but still over 18) according to someone else on another message board. I checked around, and found some info that pointed to those ages I mentioned.
I was assuming that if the ages were really changed, it might create some translation discrepancy. I wanted to be informed.
Turns out the only thing we currently know is that Masumi is 30 officially, based on the interview with her voice actress. The other characters ages are just hearsay as of now. though Zalas did say there maybe was a scene in which Aoba says she’s older than Tsukasa, and claims that if he’s 20 then she’s 22. That may have been a joke though…
Oh, and the reason most Erogames don’t give ages is because EOCS/Sofurin doesn’t allow them to have characters under 18 in eroscenes, so they try to avoid the age issue altogether.
