Good evening Meg!
Thank you so much for your interest in this project!
I really enjoy your acting and your voice, but i'm not quite sure it will suit the librarian... but more Alfhildr. Alfhildr is a side character who has her own quest and "intrigued" in the game (she has a kind of love story with another side quest character).
If you still want to try the librarian here some additionals information about her (without spoil):
she is very humble and trying to act tough most of the time, so she is sounds a little "emotionless" (it's pretty calm, but with her stoic face people say emotionless).
For the first line she really calm, it's been a while she didn't see new people in the library and she's pretty much on her guard when she talk to the player.
for the second line, she in telling a story to the kids, but she genuinely feels connected to the story, she's happy then switch to melancholy/soft madness to "when the onis arrives". she doesn't feel them 100% but enough to make the story alive as she tell.
for the last sentence you catch the feeling so i'm not gonna say more about it.
your voice is a little too high for what i imagine. try to think of loona in helluna boss or maybe escoffier (en) in genshin impact as a little reference of the high.
Hope it will helps you!
have a great day or night 🫶
