Sorry, maybe it was a bit too obscure! It’s a meme about feminizing voice training.
First panel is Frieren; she has a fairly deep voice (for anime at least) but obviously feminine. Should be achievable, and I’d be really happy if I could sound anywhere close to that (although maybe a bit less breathy).
Second panel is Makoto from Sempai is an Otokonoko - the scene where he’s(*) standing in front of a blackboard after being outed. His voice is quite soft and high, but sounds like a boy (in-universe he can pass) – which is kind of where I’m at most of the time.
I’m talking about the Japanese voice acting, btw. I assume the dubs use similar voices.
(*) There’s apparently some debate over this, but since Makoto rejects wanting to be a girl and explicitly says “I’m a guy”, I’m going to assume femboy rather than trans girl.
Ah, that sounds like a weird translation then. Looking at the manga (I think the line in the anime was similar), Makoto says:
That is, “I want to live as me. I’m a boy but I like girly things.”
OTOH, as you say the reaction to being perceived as a girl (and trying to pass as one at school) is pretty telling. But egg prime directive, and all that.
