Authors note and a system status

  This is my first story that I wrote for fun I'm open for suggestions on where to go with it as long as no one asks for a harem because I've already decided that this is a Freed and OC story. Since the story will revolve around the OC and Freed I will need some suggestions as to what The will be doing it I like it I'll give you credit at the start of the chapter and right now I need a suggestion for chapter three what is Freed going to teach Niji and how will he teach her? Also should Niji use her stat points if so which stats?
