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

"So, who are you guys really? For you to dare pretending to be members of my clan, you sure have a lot of guts. Tell me," I asked.

There are still five of them. I should have killed one so they won't dare to fight back. I don't think I need to do that. They saw me splitting the Salamander in half.

So far, none of them seems to know that I'm an Aura user. But just to be safe, I'll kill them. But that's for later.

"…We are part of a slave-trading organization," said the girl who invited me.

She told me everything she knows. While her voice is obviously shaking.

No one among them dare to stop her from talking. They know already that they're no match against me.

So, these five are from a certain organization for trading slaves. But they should be illegal, right?

In the end, even after all that happened, there are still some nobles who wanted to have slaves. Wanted manpower no matter how they get it.
