Seeing her cute reaction Dexter just gave a smile and started to collect table and chair into his inventory then he took her in his embrace and started to wait.
Seeing that they just stood in the same place Valera asked in confusion," Dex why aren't we going anywhere?"
To which Dexter just gave a smile and said," We are waiting for someone and he should be here any min."
And suddenly Dexter saw a shadow flying towards them," looks like he is here."
Valera looked in the direction that Dexter was looking and started to search for their guest but wasn't able to see anyone and said a little annoyed," But I don't see any one."
Dexter just kept silent and finally after the shadow was able to see them he directly teleport in their front. Seeing another Dex Valera was shocked but without her asking Dexter replied," It's my clone that I sent to underworld after you fell asleep in hotel. It was here to collect information for me."
After Dexter finished explaining the shadow clone vanished into a puff of smoke and all the information was transferred to Dexter. After sorting out memory, Dexter finally understood the current time.
Kuroka (Koneko's sister) was still going through experiment and still has some time until she rebelled, but he didn't want her to be pushed to that end as she was really a sweet girl, so he decided to go to Kuroka first before anything.
"All right we are going to meet up with one of your sister. But you will need to be strong while seeing her alright" Dexter said in low voice and seeing Valera nod Dexter transferred both of them to the vicinity of place where she was being experimented on. Seeing the high security Dexter just erected a space separation barrier and started to move towards the lab.
After turning few corridors they were finally able to enter the lab. It was an open lab and Kuroka was tied to a bed and was being injected with a yellow serum. They were surrounded by few people in lab coat and a High class devil was looking at the statistic on some equipment. Seeing this Valera stared to shiver and caught Dexter with all her strength that she could master.
Seeing her like this Dexter just put an arm around he and said," If you want to recover from this trauma you will need to get stronger." Then he looked at Kuroka and asked, "Do you know the reason she is willing to suffer?" seeing her shake her head Dexter looked into her eyes and continued," It's to protect her little sister from suffering her same fate and once she lost her reasons or died, they will start to experiment on her little sister. So to protect her she needed to be strong and endure." seeing her still shaking he continued in soft voice," I didn't bring you her to attack your confidence, I brought you her to affirm if you are still willing to be with me because after you join my family, you will be the eldest in our family and will need to get stronger so that no one can bully your younger sisters." Hearing him talk about family she became stunned then started to look towards kuroka.
Dexter also looked towards Kuroka and suddenly everyone in the area fell unconscious on floor. Then he move towards Kuroka who was still struggling in exteram pain. He looked at her pale complexion then put his hand on her stomach and started to rotate the energy present inside her to absobe all the nutrients of the injection and eject the harmful chemicals in her body. While doing so he started to repair the damage done to her body due to experiment and made her body eject the harmful chemical present in her body. After a few min Kuroka finally regained her normal breathing and became unconscious. Seeing her in pitiful state Dexter was really angry at the devil but was unable to help her except transferring her into Reas's servant.
While Dexter was treating Kuroka Valera just stood in her place and looked at everything and when Dexter turned around he could feel that her emotions has stabilized by a lot and there was even a fire in her eye to get stronger. Seeing this Dexter was really relived as he didn't want to take any fragile girl into his family as his path forward will be filled with fights and more fights, so he at least want his wives to be able to protect themselves.
Finally he moved towards Kuroka's Master the High Class Devil and put him in strongest genjutsu and gave order," You will go to Gremory house and will trade Kuroka and Koneko with Reas and will also tell Reas about their strength and suggest that she make Kuroka a bishop and Konoke a Rook. After you finish the transfer you will return to your house and will release all your servant and distribute your wealth between them except for keeping small property for yourself. After completing everything you will drink this liquid but until then keep it safe a let no one see this bottle." Saying this Dexter put a small bottle in his hand and started to move towards Valera and after finally taking a last look at Kuroka he again put a space barrier around them and everyone started to wake up.
As everyone in the room regained consciousness they looked at each other in confusion, their master released his aura and ordered everyone that no one was allowed to talk about anything that happened in the room. Everyone became confused at their master's sudden outburst and swore to never revel anything that happened in the room. Seeing that everyone has swore he dismissed everyone and told them to take Kuroka to her sister.
Dexter and Valera watched everything happen and after the devil has made a successful transaction with Rias in front of her mother and convinced her to use Bishop and Rook on Kuroka and Koneko he left for his house.
Seeing that everything went according to plan Dexter Finally took a breath of releaf and looked at Valera who was looking at everything silently and finally asked,"what was in that small bottle and is Reas also going to be my little sister?" seeing women's intuition taking effect Dexter just gave a nod with smile,"In that bottle was a liquid that was able to make anyone who has drunk it feel all the pain they have inflicted on others and about Reas I don't know if I will be able to capture her heart, but I will try." Dexter said while looking at Reas.
"So have you made your mind?" Dexter asked Valera and she gave a firm nod.
Seeing that Valera gave a nod, he took her into his space equipment. Seeing the change in scenery Valera looked at Dexter with question but he ignored her and said seriously," With time you will know everything but you will need to become at least Demon lord level to know my secret." After pausing for a few mins and arranging his thoughts he continued," According to what the clone discovered about your background, you were made from Egg of a Nekoshou Priestess who had purest natural senjutsu in this world and sperm of last demon lord. I don't know how they were able to get their hands on that but due to two conflicting natures they cancel each other. And it was because of it that you were born but if this continued you will die within 5 Years."
Hearing that she only has five years Valera became depressed. Ignoring her mood Dexter continued," So to be able to make you control them, we will need to separate them inside your body and while sealing one energy you will need to control other. After you have become proficient in both of them we will merge them and this will be the hardest part so I will make preparation for that as it will bring your heart demon out and you could loose your life." After Dexter finished explaining to Valera who was looking all fired up for practice was stunned by suddenly appearance of an ordinary man on Dexter's side Valera looked at him weirdly as she can't feel anything from him.
Dexter looked at the man and smile," Master you look in good shape."
"Brat you found a rare gem for energy cultivation this time, so I am personally going to train her in every type of energy. You will be shocked when you will see her next time." Master replied excitedly.
Dexter looked at him with resentment," You really are biased Master you even examined me before teaching and took her in as if your test doesn't matter, but if you want to teach her I don't think anyone can be better than you and please help me train a tribe that I will send to you. And I will give you a right to manipulate the terrain and gravity."
"What do you understand brat and since you brought me such a good disciple I will also train that group." Master replied a little annoyed.
Seeing that he has managed to convince him to train the Nekoshou Dexter took a breath of relief. Finally turning towards Valera was with question mark over her head, so he gave introductions and told her that he was the best person to teach he and he was also his only master. Then he told her that he will send the Nekoshou tribe in a few days and to look after them and finally giving her a kiss on lips he moved out of the equipment leaving Valera with his master and he was really looking forward to her growth.
