Yurik is a supporting role.
Anise (still a baby) was kidnapped by Dietrichs pregnant mother and was killed alongside her unborn baby. So they thought the mother was killed but her baby survived. Dietrich is the ML and maybe he got the idea of Anisa not being his real sister because of Anisas haircolor or of her being different from all others of his family. I'm not so sure why he knows that she is not his real sister.
is Yurik the ML?????
