Fate again.
If she isn't her (Lucas') mother, then is it possible that she's Cordelia's/Enomoto family member? I remember Enomoto said she's doing this out of personal revenge, and the only thing that's mentioned in her backstory so far was how she was an illegitimate child and things about her family. Lucas' mother reminds me of Cordelia's face (especially the eyes), but that might be because of the author's artstyle. Still, her mother was mentioned to be a Zerestian woman who married a Nobleman so yeah idk man
Thanks for the translation!!
