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

"And that's everyone. What do you think?" I asked Andro after introducing everyone to him.

"I'm happy to have a lot of friends. But they won't stay with me much, aren't they? You are busy with what happened in your world, right?" Andro asked.

"If I find anyone who doesn't want to participate in the war and just live peacefully, I'll bring them to you. I don't think it's a good idea to build something on your back after you complained how itchy your back was, but we should be able to build some tents. And there's even a huge dent on your back where we can collect water from the rain. We'll make you a living fortress in this world, where everyone who only want to live peacefully without doing anything take refuge," I said.

Though I'm the one who wants to live peacefully the most. Well, it will be difficult for us if I'm not fighting. And even if I don't participate, in the future, the cult will attack this world. After that, where else should I escape?
