I was looking at the weapons that returned to the gate when I decided it was best to step up my plans to make that idiot suffer. So far, he had no luck picking up women from this world, so he took to summoning women using his system. This is a crime up there with isekai kidnapping children to make them fight a demon lord.
Absolutely horrendous!
Now I know what I am going to do. I will begin slowly breaking away the mind-altering effects from the women of this world. When they naturally fall apart, I will move to those he summoned and help them break away all at once. By this time, he will figure out the cause and come looking for me.
When he comes looking for me, I need to have preparations in place. I used the metals in my gate to build a containment area, while enchanting it to completely restrict his movements and system. I will strike the moment he is vulnerable.
=================Time skip 1 year===================
This was the best year yet! Every day his "lovers" would grow further away from him and I would get to watch from the comfort of my nice little bean bag chair. Comfy.
With only his kidnapped victims left he was a blubbering mess. He stopped training to spend more time begging for another chance from the people he willingly brainwashed. While he was crying and screaming like a little kid throwing a tantrum, I struck the final blow.
I teleported to the trap set just for him. Prepared the long-range mind clearing and mind freeing spells and hit all his summons at once. He opens the door to see every girl looking at him with crystal clear eyes. His system already sensed the spell in the air and alerted him. "What!", he cried out.
They all noticed him and knew what he had done to them. There was cries of hatred and tears from all the girls. Some of the girls were thankful for pulling them from the terrible world they lived in, but they did not go easy on him. By the end of the fiasco, his system had to send them home because they were starting to get violent and had almost as much strength as him.
He was a broken man. He was "betrayed" by those that he loved and now knows the cause of it. He told the system one thing, "Bring me to them!". He was gone with a flash and in front of me.
His eyes widen in shock from the realization.
"You! YOU! It was YOU! Why, why did you do it? Why did you take those that I love away from ME?", he screamed hysterically while pointing at me.
I opened my mouth to speak when a needle covered in the strongest sleeping and paralysis poisons I can make hits him in the back of the neck. His eyes widen in shock and he was about to say something before his body was fully paralyzed. He fell to the floor already in a deep sleep.
The 'me' in front of him faded away while my real body appears behind him with my gauntlets already on. I place my hand on him while he sleeps and synthesis out his abilities. He has so many abilities from his years of training in this world and now he will only have his memories of them. The abilities all take the form of a crystal, including his system with infinite system points.
I put them all in my gate before taking out the ability he got from eating the lightning fruit. I am not eating this horrible thing, but I will use it on my gauntlets. With a quick crunch between my hands, the gauntlets turn black with white accents and blue outline around the accents. The forms my gauntlets take get better the more I use them. Its great, but I never use it because I like to rely on my own abilities.
I take out a giant cauldron from one of those wuxia novels that was in my gate. It was one that came back within that ten-year period and gained the ability to refine materials. I move the trap that I set up above the cauldron and watch it melt down and refine into bars of metal and planks of wood. Satisfying.
Now to deal with this idiot and give him a taste of his own medicine. I focus the magic in the air and rip out his FUCKING SOUL! HA! With my concentration on him I activate world travel for the first time, but not for me.
The world I choose is HSDXD, this is a harem anime about all kinds of mythological creatures hiding in the modern world. In the world travel options you can choose everything, from your body and special abilities, to requests for changing the world you arrive in. I set it so that our dear reincarnator will be reincarnated once again as Rias Gremory's little sister. Special requests are that 'she' will not be able to use magic of any kind, so she will need to fight up close and personal.
Of course, she still has her memories so whatever fighting style she trained in she can train in it once again. If only she did not rely on the system to improve it for her, she would have an easier time getting to where she was.
This is her punishment for messing with the minds of good people for her own selfish reasons. All that is left of her old life here is the body which has long ago died from the shock of its soul being ripped out. With a *whoosh* of my hand the body is set ablaze and I teleport away, ready to close the door on this chapter of my life.
