Now we are in front of Naberius family's lab where one of Naberius family member is experimenting on nekomatas energy. when I reach here I saw two middle class devil guarding it I just kill them with [space wrap].
[Congratulations issei you got 20,000SP for killing two middle class devils]
Issei :"Jen only notify me when it is clear"
After which I killed all devils that were in my way when I reach the inner lab I saw 6 devils who are in lab coat, using my [Appraisal] I can see 3 of are middle class ddevils, 2 are high class and last one is a low -ultimate class devil. There is a girl fixated on table with shackles when I saw her anger started builting in me.
I just put them all under Genjutsu they were all below my level so it was not a problem me and Rose got near to her and free her she was barely conscious after seeing that she was free I gave her a senzu bean from my system.
after eating that she was fully healed and all toxicant substances in her body got cleaned. She fell unconscious on me after which I just gave her to Rose she held her tightly and just took her to my world then I released mid and high class devils from my Genjutsu.
Mid-Devil 1: "who-who are you and how are you here"
High-Devil 1: "and where is the girl tell us otherwise we will kill you. "
Hearing them my anger built up more I just used my [space wrap] to wrap some small parts of their bodies like fingers, knees, nose, stomach. Then I used [water bullets]and fire it to them I made holes in their bodies. I then used [wind slashes] to cut their limbs. After which I used one of my new skills
[Burn] on them it slowly burn people not to the point that they are killed. I can hear their screams
"Aghh... why-why"
"Noooo.."
Then I released the Ultimate class devil from Genjutsu when he hears their scream he asked me
Ult- devil: "who are you and why are you doing this with us'
Issei :" Ohh, you can see their pain but not that girl's"
Ult-Devil :" She is just a lab tool"
After hearing him I don't pan on killing him without making him feel the same pain as Kuroka, I bought a Poison from my system for 75,000SP it makes people suffer from feeling of like hundreds of burning snakes moving inside their bodies for 2 months after which it takes their life. Then I put him again under Genjutsu and make him dring that potion Then I released him and he started screaming like a madman. I just leave them be and moved towards a position where I can feel another presence and I know who she is. When I reach their I can see a small girl nearly 7- years old with white hairs and cat ears crying there. I reached to her and hugged her and said
Issei :"Don't worry,You and your sister are fine now"
when she sees me she got a little shocked but seeing concern in my eyes and actions she calms herself and asked
Koneko/Shirone : "who are you and what do you mean by saying my sister is fine"
Then I just released her from my hug and ask Rose to bring Kuroka back and when they appeared with kuroka fully fine and fresh.She said to koneko
Kuroka :"He is Issei and he is also the one who saved me and other Nekos Nya~"
Shirone/Koneko :"big sis, you-you are fine, i-i was worried about you "
Saying this she got to kuroka and hugged her while shedding tears. they both hugged for a while after they separated I told them
Issei :"you both are fine but now shirone has to go to someone who will help her getting stronger and also will treat you like family"
Shirone :" i don't want to part with my big sister Nya~"
Issei :" you don't have to worry about that I will give you something and Kuroka will come to meet you whenever she have time and you can live with us when you are strong enough"
saying this I just moved towards Rose and hugged her. Seeing their condition she is very sad about it I just console her while Kuroka is talking to shirone to make her agree after sometime I broke my hug to Rose who is now feeling a bit better and said
Issei :"Shirone are you ready"
Shirone :"Fine but you and Rose sis will also have to come to meet me"
Issei :"Ok but train well there and make good friends"
After saying this I just created a clone using my [Shadow clone jutsu] and sent it with shirone to Gremory house.
Then we returned to the lab where scream can still be heard I created five wind slashes and killed them leaving only the ultimate one.
[Congratulations issei,you got 384,000SP for killing 24 low class devils,16 Mid- class devils,2 high class devils]
when I heard this uwas a bit happy, Then we walked out of there and Kuroka suddenly asked me
Kuroka :"Issei, can I also be your girlfriend like Rise and other Nekos Nya~"
while having puppy eyes and shaking her tail left and right How can I say no to her when I already panned to take her in my harem.
Issei :"why not you are already my girl"
when I said said that she jumped on me while hugging me When I tried to touch her tail she jolted and jumped bacward while having a beet red face but the feeling I had when I touched it is good good it was so soft and good. seeing me and Kuroka's flushed face Rose just giggled and bhearing this we are back to reality Then we teleported from there to human worldworld using a travelling tailsman.

In Gremory HouseHouse
Grafiya's Pov
Today while I was walking I my room I suddenly felt someone in front of our gate. I teleported there and I can see a small child with a white haired Nekomata. then I asked
Grafiya :"hello my name is Grafiya Lucifuge, I am maid you Gremory house, Can I ask what are you two doing here.
Issei's Clone :"hello, She is one of the nekomatas that devils had kidnapped and I want you to take her in your house"
Grafiya :" and why would I do it "
Issei's clone : "she can be a good rook for your heiress Rias Gremory peerage."
saying this he suddenly poofed up leaving only smoke even I can't detect where he is gone I looked to the small girl
Grafiya :"So girl you are ok that he leaves you here to us"
Shirone :"Yes, he said you are good people and will also help me getting stronger and he and my sister will also come to me sometimes"
Hearing her and seeing the determination to get stronger in her eyes I just took her in and went to Rias's Room to introduce them to each other.
