His boosted gear

He carried on with his day, and It was now night, and Issei, Rias and Asia were in bed, sleeping, and Ddraig, the red dragon emperor appeared to him in a dream.

“What is it?” Issei inquired.

“I have an idea which I’m sure will interest you.” Ddraig said.

“Go on then.” He said, curious about what he was going to say.

“Your boosted gear has been in use for many centuries, correct?”

“Yea, this things old right?”

“Over 10,000 years old, but over this time the gear has gained some uses other than for battle, some even for sexual use.”

Those last few words got him paying very close attention “Like?”

“Many, but for now, I will say the most important one.”

“Which is?”

“Mind control, unbreakable mind control, that is.”

His mind went blank, not able to ingest that.

“w-wait you are saying that I can make people my puppets?”

“Yup, all you have to do is look at them and say _____ and they will be under your control.”

His eyes widened, realizing his full potential “r-really!”

“Yes, now it’s time for you to wake up....”

“w-wait!” He said, leaning up from his bed.

He looked beside him, and Rias and Asia were laying by his side, so who does he test it on?
