Cleria and her husband are dead in the eyes of the world. I created a simple illusion when I saved their lives, making the people hunting them think that they already died at their hands.
Cleria was being hunted by the Devil executioner squad hired by the Devil council after she found out that king pieces are still being used in rating games by a few teams and some of the Devil Council Members are also involved.
After I saved their lives they had nowhere to go so I offered them my protection, in return they would become my servants.
They were hesitant but I let them see the benefits first before they decide.
They stayed in Kelinstar but they aren't allowed to leave. If they decide to leave, they would have to meet me first so I can remove their memories or they would have to become my servants if they want to stay.
Cleria, her husband and her peerage were walking out of the dungeon with happy faces.
They are the first group to complete the dungeon I created, though at the beginning they weren't even strong enough to reach the 7th floor.
Today they completed my 35 floor dungeon.
Klein: "Congrats, I see most of you have already reached peak high class level. And Cleria you finally entered the Satan Class."
Cleria: "This, wouldn't have been possible without you help. The Dungeon experience with the Space-Time chamber really helped us speed up our growth."
Klein: "Right, you all seem tired. I shall not hold you any longer. Take rest today but I want you all to come and meet me tomorrow. Tomorrow is the deadline of the agreement we had, so I hope you have made up your minds."
Saying that me and Kelly disappeared from the spot.
...(Kuoh Town, Morningstar Residence)...
My parents, me and Kelly returned back home. The summer holidays are about to be over. Me and Kelly will start going back to school in a few days.
I was sitting relaxed in the bath tub when the door slid open...
Kelly: "Onii-chan, want me to scrub your back?"
Sigh.. I just nodded. Saying anything else would be of no use, my sister is stubborn and she is very attached to me and it makes me worry about the future.
[Klein, Kuroka and Shirone have been taken to the Nebarius Clan. They will start the experiments on the sisters in a few days.]
'So it's finally time!' thought Klein.
...(Next Morning inside Kelinstar)...
Klein: "So, have you decided?"
Cleria: "We are willing to join you but we have a condition...
Klein: "I'll be going to the underworld for a few days. Keep the barriers up in the place and if you are in any trouble just send me a telepathic message. I would prefer if you stop hunting rogue devils and fallen in the town for a while."
Dad: "This is quite sudden, is there a problem?"
Klein: "No dad, but we might have a guest when I return."
Mom: "Take care, son. Don't do anything risky."
Klein: "Don't worry mom, there isn't many who can harm in this world and there is none who can stop me if I want to escape."
Kelly: "Mou... Onii-chan, why are you not taking me with you?" Kelly says while pouting cutely.
Klein: "Next time, I promise."
After saying that, I teleported to the underworld near the Nebarius Clan research facility.
Klein: "Kuroka... I won't let you suffer this time!"
It's been a day since me and Shirone started staying with our new master. After our father betrayed mother and killed her, he sold us to these people.
We haven't been treated badly by them till yet and they have been rather kind but I don't know why, something doesn't feel right...
I keep an eye on the sisters while keeping myself invisible.
I see as they sedate shirone and blackmail Kuroka to go through the experiment or they would use her sister instead and Kuroka agreed.
As she was being taken to the experimental chamber, I took it as my clue to make my move.
I first rescued Shirone and teleported her into Kelinstar before turning all the devils into blood puddle.
After that I went toward the chamber they took Kuroka to.
When I entered the room I saw some of the devil scientists strapping her up on a medical bed.
I quickly teleported to them and ripped off their heads with a single wave of my hand.
The other demons who saw this were stunned before they quickly reacted and pounced forward to catch me.
I ignored them and stopped the time for everyone except me and Kuroka.
Klein: "Hey.. are you alright?"
Kuroka: "They took my sister.. please help her."
Klein: "Don't worry I already rescued her and sent her somewhere safe...(I open a portal) this portal will take you to your sister stay there with your sister till I return after destroying this place."
Kuroka noticed at this moment that all the people in the room were frozen as if time had stopped moving.
Kuroka: "Wh..who are you?"
Klein: "Not the time.. I'll tell you later. Now go!"
After she left, I turned towards the frozen devils with an evil grin on my face.
I snap my fingers and time starts again and the devils come flying towards me only for me to phase through them.
Devil 1: "Who are you?"
Klein: "What does it matter to the dead?"
I reappear near him pierce his chest with my hand and pulled out his heart along with some broken ribs killing him in an instant.
I do the same with the others... turning them into blood puddle, ripping their heads, pulling out their hearts.
Afterward, I fly into the air above this laboratory of the Nebarius clan and created a giant ball of chaos energy in my hand and sent it towards the place, turning it into dust before disappearing.
This's an experimental test for reading assistance in case.
