Azyl Academy

Book excerpt: I was getting ready to graduate, with only one semester left, when I took a ski trip with my fiancee and ended up dying to save a little girl's life. This wasn't the end, though, as a deity chose me to save another world. I woke up in the body of Kupiec Aiden, in a world where magic was real. Unfortunately, unlike many isekai novels I've read, I retained none of his memories, and had to learn everything. HIs family took me in, and I recovered from his sickness before learning about magic, or Aether as they called it. I discovered that I had immense innate talent in Aether Gathering, and was offered a scholarship to attend Azyl Academy, the city's premier institution. Where do I fit in this world, and how am I going to be key to saving it?
