Shin's Twin Sister (Magi's Grandson Fanfic)

My father introduced this anime to me and I just wish he had done so sooner! This story is gonna be an OcxOc because well most of the class guys if not all of them are engaged and also I wanted to spike things up!

As we all know Shin was reincarnated if not reborn into this world with no real memories of his past life, the same was for Stella. Though they didn't know each other in the other world they did die at the same time the same way.. then? Then the two were reincarnated to this magical world as twins. What happens when there are two monsters instead of one? What happens when August younger twin brother comes back from knight training to learn magic as well to become a good knight/escort for his brother? Read to find out!
