Help "control"

(Sorry everyone, i click wrong when writing)

Using Time Stone to freeze the time except for him and Gasper, Issei wants to ask him something personally.

"You are scared of harming the others by your power, right ?"

"... yes, i don't want ... but ..."

"I will help you. As you see, i also can stop the time. We have unlimited time to practice. I will help you master a bit of your power"

Using Space Stone to go to a blank dimension, Issei practices with Gasper for entire three months. The boy now can use darkness very well to create creature-like weapon as well as surround the enemy in darkness till they stop breathing.

"Okay, you will remember all the practice you have gone over, but forget about my time stop, you will say to everyone that you accidently stop the time and trap me as well as yourself in darkness"

However, Issei still not let the time restart as he marks Rias.

"During the meeting, you will keep calm before the Fallen Angel, if the meeting is over peacefully, you will not fight them as long as they don't go first, also you will think about me as your lover figure, and become my loyal submissive bedmate is your secret desire from now on"

Yes, he wants Rias to be in the collection, but at first he must make sure there are no any wars more.
