A Demon's Teacher

Yup, Raegen trains Sera. This is going to contain a small retcon, with it being that Sera obtains the Rebellion much earlier than I said before, with her gaining it after Raegen defeated Viktor, who had been wielding it. He made Raegen promise to give it to her, and train her to use it. Raegen promised, and would end up teaching Sera everything he knew about swordsmanship, teaching her some of his techniques, while she developed her own.
