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

"Roy, I will go back and have a chat with my master. I may be much weaker than I was in the past, but maybe master or anyone else here can help me get stronger. Maybe using technique without Aura. I'll leave a lot of Blobbies with you," Victoria said as she left.

I am now wearing Blobbyarmor instead of Victoriarmor. But the amount of Blobbies she left is enough for me to shoot a barrage of bullets without having to worry that I'm wasting bullets.

"A slime that can transform into anything you want as weapon. In the past, your familiar will be every Aura users dream familiar. But if you use it as weapon, does it mean that you have no main weapon?" Mona asked.

"Although I'm more proficient in spear technique, you're right that I have no main weapon,"  I replied.
