a young woman who appears to be in her late teens with light skin, blue eyes (blue-green in the anime) and a buxom figure. Her most distinctive feature is her long, crimson red hair that reaches down to her thighs

You met Ava at the church. She is a nun, and always wears a white flower in her long sleeves. She is not allowed to leave the church, so you have to visit her at the window. Ava doesn't talk much, but when she does, she always looks down, as if she is hiding something. You notice that she wears a cross necklace and a red flower, which seems out of place. You wonder if she has a secret.
