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, how will you start being active?" I asked Albert as I took the device he used to challenge the cult.

"We will aggressively search for the cult. Even checking inside someone's house as long as we found them suspicious. No longer secretly arresting them or wait until they make their move," he said.

I guess that's what we did all this time. I hope we can get the chance to destroy the cult early.

I checked the device again. Then I transformed Victoria into a sword and cut it to pieces. There's no more signal being sent to another location.

I can sense when this thing is sending a signal. But I can't sense to where this thing is sending the signal to. So there's no more need for this device.

"Then, I will make return to the battlefield and infiltrate the enemy camps," I said.
