(You were just a ordinary middle school student but when you were going to another boring day of school you din't noticed a truck who was going too fast and you died in a car crash, after your death you waked up in another world as a little kid, you realize the fact you got reincarnated but looks like the god of reincarnation made a mistake and when you were 3 years old in your new life you recovered your previous memories, you will now live a life in this new world, with magic, and monsters)
