I've come across a voice line that is wrongly placed in Volume 1 with the female love interests. I was also using She/Her pronouns myself but I'm unaware if it influenced this somehow as well.
In text, Kasumi says "So those are your true colors, huh? Resorting to violence?" but the voice line says a different quote from a previous text of her. The next part right after this one is correct again, so it's just that part of the phrase.
Great fangame, by the way! I really love what you did here to represent each character and the story. It's good to see a fandub of this series since I don't know Japanese myself, and to also have a more visual and interactive representation of it.
