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

Sigh… I thought that even though we are outnumbered now, we can still win easily because of the help of the expert level mages. But it seems that I was wrong.

Why did Albert want to only give the chance for everyone to fight, except for the expert level mages? It will be easier if they join and defeat the vampires, right?

But no! The expert level mages are just for support and reinforcements in case we're losing! Even the angels and the werewolves were not part of the plan. Only humans with power of advanced level or lower.

"We need a strategy that didn't include the expert level mages because they are powerful. During the real war, they will most likely be given other jobs. The werewolves and the angels are also our trump cards. I can't ask them to not participate, so I told them to protect the areas other than from where the vampires will be coming. By the way, what are you making?" Albert explained his intention, and then asking me what I'm doing.
