It would be hilarious if you taught her everything that Riveria refuses to teach Ais for fear of corrupting her by seeing her as too young, omitting that she is partly human and should know certain things about her female biology.
You must try to get around the artificial dungeon Knossos and gather the materials they collect so you can build your own safe house as a secret project.
You should be able to "influence" Riveria to expand its mentality and develop new "Skills"; especially for its unfortunate idealization that Mages cannot fight with fists or kicks.
