   Summary

   The Alberichs' life motto was ; "For duty".

   The Ragnvindr's family motto was : "Shine true".

   When Kaeya Alberich gets adopted by Crepus Ragnvindr, this leaves his cousin, Dainsleif Alberich, bereft of a purpose.

   He does not accept it. Is that Ragnvindr family even good enough to raise Kaeya ? He shall verify it with his own eyes. And if they aren't… Maybe he will take his cousin back to Khaenri'ah.

   Crepus Ragnvindr, for his part, isn't letting some little blonde bitch breaks his family apart.

   (Or : Dadsleif - except Crepus doesn't approve… at first.)
