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 put on the helmet again before facing the enemies.

I killed one. But there are still five of them.

The space mage is the most troublesome one. Then there's a sword and shield man who is also a healer. There's a spearman and a spear and shield man. Lastly, there's a swordsman.

I killed one of them before. But I don't think he's anything special. I should have killed the other sword and shield man instead since he's a healer.

But if the person I killed was a healer, then I guess the result will be the same. Let's just be glad that I killed one of them and focus more in killing the rest.

"It's impossible to find out who he is without killing him. Let's just kill him. It will be better that way instead," the spearman said.
