[Aoi's not sure why this weirdo is laughing about the name 'Jeanne', but whatever. He's totally assuming Jeanne is a much-younger woman that Kirei secretly wants to tap.]

There's nothing wrong with it, but if she doesn't like it, a nickname would be better. You don't gotta stick with a name you hate just 'cause your parents gave it to you.

[There's some bitterness in Aoi's voice. Sometimes parents are shit people who leave you, and Aoi might've dropped his name if it hadn't also tied him to Akane.

Besides, nicknames and code names are cool unless you pick something super lame that only makes sense in a timeline you didn't get to explore.]

There's an easy solution. Ask Jeanne what she wants you to call her.
