===============================
It has been at least 2 weeks have passed since the Fallen and Asia have been living in his home.
And during that time, the Fallen Quartet and Asia were able to get along and spend time with each other. They talked about their likes, dislikes and what they enjoyed doing.
As for Issei, he would still maintain his distance from them at times, but he would be moderately civil with the girls. Especially Asia as she was the only other human(normal human) living with him.
However, he can clearly sense the jealousy from the Quartet when he did so but he ignored it.
Right now, it was Friday, 11:05a.m at the Academy. And Issei was on top of the roof lying down while staring at the clouds.His mind was clear of thoughts and his mind was at peace.
Until, he sensed that one of his clones that were on patrol had sensed something dark from afar. But luckily, that clone had it under control.
===============================
The scene switches to an old mansion far in the East of Kuoh Town. And within it was an invisible Issei Clone that had just entered the house with intangebility.
And as he entered the livingroom, he found who he was looking for.
A tall, nude, beautiful, bosom young woman with brown hair, black markings on her body & pale skin, and sleeping on the ground with dead human bodies around her.
She was a Stray Devil.
The Issei Clone thought,
Issei Clone:Found you.
And with a single step, he disappeared and lightly touched her forehead which made her entire body crumble into pieces.
The only thing that was left was a solid brown cube on the ground.
Then the Issei Clone went to the cube and picked it up, then teleported away as the remains of slowly crumbled and disintergrated leaving nothing left.
Then a second later, the clone appeared in Issei's room and put the cube in his drawer counter.
Then he thought,
Issei Clone:She is cleansed and preserved Boss.
Issei:Good work. You can dispell now.
The Clone nodded and did so. And Issei, he was just chilling and looking up at the clouds and smiled.
Issei:Got another one.
===============================
After school was over, he arrived home, greeting the Fallen who had finished doing the chores around the house.
He congratulated them on doing well, then told them that he will be in his room for awhile and that he will be introducing someone to the group. They nodded and understood.
