Roy died during a war against the Evil God Cult, but somehow, he returned back in time to 30 years in the past where he was just a boy who awaken his summoning magic. 
Just a few days before his death, he became the only Aura user in a world of magic. 
Using his knowledge and experience, he will become an Aura user again, faster than his previous life. 
Accompanied with a shape-shifting black slime, he will make sure to protect everyone he cares about and win against the Evil God Cult.

The Only Aura User In Magic World

I woke up to see myself in Bernard's mansion in Arturo. Seems like after falling asleep, no one wakes me up as they are still having a discussion.

I go to where everyone is to see if they made some plans for the cult or not.

"So, what will you do now?" I asked.

"We'll return to our own kingdom for now. As for you, the only thing we ask you for is to get stronger," Old man Henry said.

"And as our transport method. We need you to bring us back home," Lynn said.

Well, that's what I do most of the time. Though I stopped training as much as before because I have to teach now.

"Don't worry, Roy. I heard from Dean that you should have cover the lesson that can be taught. As for the rest, he said to not worry about teaching them at the moment. You don't need to teach anymore, and Sara can cover for you. You will be able to train hard again," Albert said.
