The Time I Reincarnated as the King of Knights?!

Dying is a part of life and if you're lucky maybe there's some kind of heaven or afterlife, but I didn't expect my afterlife to be reincarnation. I know reincarnation is a belief already present on Earth, but meeting someone calling themselves "The Author" was totally unexpected. After making some decisions, I start my new life as the King of Knights in the world of Tensura and try to see what kind of impact I can have and maybe find someone to get close to.
