Hmm, consider it comic logic. Id age up edna to be at least 1 year behind edward and have it to where this is the second year for kyuna and edward, but be the first year for me and Edna as for how the logic would go, Krezz had Edward with his canon wife but ended up impregnating a wolf mistress around the same time (im going to theorize it would most definitely have been in an orgy with his wife and some friends where Krezz just didnt know the wolf was on an unsafe day later finding out and officially taking him in) giving Edward and Kyuna roughly the same age.
I on the other hand would have been the baby between the wolf and possibly either another orgy result or from just having a partner later on but unfortunately discover they could not take care of me and so put me up for adoption, where again, Krezz took in on more child hearing I was Kyuna's biological younger brother.
(as for krezz's in canon wife from the comic, im just going to wave it off for now as I dont feel confortable dealing with parents divorcing and all that right now for personal reasons and so in this comic krezz is currently a single father but is dating Crystal who just so happens to also be attending collage XD ) Sorry for the text dump hehe.
