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

The monsters coming from the stampede are mostly goblins. Many of them are ordinary goblins that most beginner level mage could defeat easily, but there are some powerful variants of goblins as well. And they outnumber the hunters and the guards.

If the expert level mages are allowed to fight as well, it could be over soon. They can use a large-scale magic that would kill most of them, if not all, easily. But we are not supposed to help unless we are losing.

But the enemies are goblins. I don't think there will be any need for us to join.

That's what I thought until I see some more powerful goblin variants appearing. Though it's not as if I have to participate.

We might get pushed back a little, but if there are any excellent mage here, even if they are just advanced level, they should be able to handle those powerful variants easily.

If there aren't any excellent mage? Then the expert level mages have no choice but to participate.
