"You have chosen and been chosen. Grow stronger and save my world."

Just one semester until graduation, and I died saving a little girl. 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?
