*Serafall Leviathan POV*

When the dragon told me to take care of the two nekomata, I didn't know what to do.

I asked him why he chose me to take care of them. I was scared, but only to hear him answer that he trusted me, so I chose to agree.

After he said that he gave me the talisman that he said to only put magical power in it which if deemed worthy for his help he would come.

When he gave me the talisman, I could feel the other Devils looking at me with envy and jealousy.

The good thing is, he threatened everyone that if the two nekomata he left with me were to be taken care of until injured or whatever he would hunt down whoever they were.

Before the dragon left, he gave the two sisters a kind of book that I did not know the contents of, only saying that it would make the two sisters stronger faster.

After giving the book and saying goodbye, the Dragon finally left.

When all of a sudden, I could again feel many greedy eyes looking at me more like the talisman I was holding and the two sisters. Well, not all exactly, just a high-ranking house instead of the other three Demons because they know how much burden I have.

If there was any danger to them, the Dragon might kill me first for letting him get hurt.

They were really greedy, I thought, but remembering those dragon words, I started to put magic power into his talisman.

And ss one of the Four Demons, this disturbs my pride. I unleashed my demonic magical power and told them "Have you forgotten the words dragon!? You all want to die"

Hearing what I just said, the demon with greedy eyes flew away like a mouse being chased by a cat.

After some discussion, we all agreed to keep the two nekomata left behind by the dragon for me to take care of.

After that, I saw two nekomata that one was a little girl with white hair and I thought she was very cute maybe sweeter than my little sister Sona, she said, as for the other one with black hair, I think he will have a seductive body in the near future when I see his figure and his possible growth.

“Halo, I am Serafall Leviathan from the Sitri family and one of the Great Demons, and I will look after you two from now on. Nice to meet you” I greet them cheerfully.

"It's nice to meet you, Great Demon, I'm Kuroka and this is my sister Shirone please take care of us" introduced the name of Kuroka's black-haired nekomata.

"No no no no, call me Sera onee-chan from now on, and I will also call you Shiro-chan and Kuro-chan from now on. Why don't we go to my place so you can rest there, I'm sure you're tired of everything that's happened and please don't be afraid of me, I'm your onee-chan from now on and will protect you both' I said to make them not afraid of me as well and I already liked them, seeing how cute they were.

"Yes... Thank you Ss-sera Oo-onee-chan" Kuroka said

But, it seems like Shiro-chan is still afraid of me, how else, I guess.

"Then let's go" I said as I lifted him up with my magical power and flew towards our house.

After arriving at my house, it was not for bragging but it was a huge mansion that looked like a palace.

As we entered, I led the sisters into an empty room and told them they could use the room as they pleased.

I even tried to give them their own room but Kuroka refused, it seemed like she wanted to stay with her brother, so I let them stay in one room which was also rather large due to too much space.

Our house consists only of my younger sister Sona Sitri the heir to our house after I became a demon, my father and my mother and me, he said, with a few servants and guards so it was a bit gloomy here since there were not many people. But, I think that will change now because we have two new family members that make me happy.

Checking on the two sisters, it seemed like they were sleeping, wow it was quick I thought.

Maybe they were really too tired, I guess I would go and tell my family about them, then I left two sisters in their room.

Two days had passed since the two sisters went to sleep and did not come out of the room. I was worried, so I went to check them out if they were still sleeping, when I opened the door I could see them sitting on the bed, it seemed like they had just woken up.

"Good morning, are you well rested?" I asked while cheerfully greeting them.

"Umm. yes Sera onee-chan thank you" Kuroka replied

Seeing Shiro-chan acting calm, I asked her, "Hello Shiro-chan, how are you feeling?"

"I feel hungry Sera onee-chan," she said as she held onto her growling belly.

"Oh yeah, soon breakfast, why don't you two take a shower first and we'll go after? There's a bathroom in the room so you can shower here" while I go and take them to that place

"Thank you Sera onee-chan," said Shirone who made me smile.

Given that they don't have a change of clothes, I said "True clothes, you don't have a change of clothes right, this is take this I made especially for you two" I took out clothes for each of them.

"Ttt-this is a bit," Kuroka said seeing the clothes I gave them exactly as I wore.

"Well now, we'll buy you new clothes later" I said happily, as I was eager to see how they would look wearing them, well more precisely, I want to see how Shiro-chan will look like wearing it.

The two sisters said nothing more and just went for a shower that only took about 15 minutes.

When they came out, they had already changed the clothes I gave, Kuroka blushed in embarrassment while Shirone seemed to not notice it but looked at her, making me drool *sniff*a LOLI!! LOLI IN MAGICAL GIRL CLOTHES!!!.. Kyaaa kawaii.

Soon, I finished admiring how cute they were and took them to the family dining room.

-------------------

When we got to the dining room, the others were now sitting there waiting for us while some dishes were still being carried by the waiter.

When they saw us, they had dumbfounded expressions on their faces, even the servants stopped in their tracks and looked at us while also having dumbfounded expressions on their faces, some even almost tripped and almost lost grip on the plate with their dishes holding.

"Nee-chan, there should be other clothes, why did you give them that?" my sister Sona said as she took off her glasses and cleaned them and put them back on.

“Now it's okay, it fits them perfectly” I replied cheerfully.

My mom and dad were just clapping.

After that, I started introducing Shirone and Kuroka to my family and also, I also introduced my family to Shirone and Kuroka.

After introducing everyone to each other and some minor failures, we started eating.

After eating I asked the sisters what they wanted to do and they said they wanted to train to become stronger and help their onii-chan later and not be a burden to her.

Out of curiosity, I asked their Onii-chan name, and they told me that her name was Silver Blaze.

Thinking of his name, I didn't know anyone from Humans to Gods named Silver Blaze, so I asked him again what he was like, and to my surprise, he said, they said it was Nag who handed them over to me.

Out of my shock and regaining my consciousness, I took them to the basement of our family training located underground.

The two brothers did not want to go underground because they were still afraid of being underground, it seemed like the trauma they were experiencing was still there.

After some time convince them and promise that nothing will happen to them as before they agree.

But before we could even begin training, they picked up three books and started reading them.

Time passed, after an hour they suddenly sat down and started chatting with each other, as if they had forgotten about me being with them.

Time passed, a year had passed that was spent in training, and it was time for my sister to go to the human world to attend a school called Kuoh Academy as a first-year student.

Kuroka now looks more mature with bigger breasts than me, taller than ever at 5'3 feet. The seductive figure and the hind hair were longer than before and looked darker, black ears that looked like a cat along with a tail on its back a few inches above its buttocks. Overall she looked like a seduction empress!

Shirone now had longer hair that reached the middle of her back but remained white but with more white luster than before, she grew slightly taller by 4'7 feet, the cat's ears and cat's tail are white, eyes that look like she's a big sister but the problem is she's still LOLI! which makes me happy.

Seeing the figure of Kuroka now made me envious, so I made a decision. I'm going on a diet! But wait do I really need to? Andwhy?

After we finished eating breakfast we went back to the basement training room.

Three months later, I was training with them when suddenly a guard came into the training room saying,

"Mom there's a 'Human' in front of the house asking about Miss Kuroka and Miss Shirone" the guard said.

"Who is this?" I asked and it made me think 'A human?'

"He said his name was Silver Blaze" the guard said

........

Hearing what the guard said I was confused, so I asked just to make sure that I wouldn't be deaf, "You said 'Man'? Don't you mean Dragon?"

"No ma'am, he is a 'Human'" replied the guard

'How could a 'Human' come to the underworld?" I asked myself, not knowing how. I asked the guard again, "How did he come here?"

"He's out of the portal, ma'am. Several guards interrogated him right in front of the house" the guard said

'The 'portal? How could a 'Human' come out of the portal!?' I went back to thinking, "Umm... You can come back now, I'll come and check on the situation" I said

"Yes ma'am" said the guard, bowing and leaving

When I was about to ask the two sisters, I could no longer see them inside the training ground. Hearing something like hasty footsteps, I tried to follow the voice, only to see Shirone and Kuroka face each other while climbing the stairs leading to the ground.

Seeing them acting like that, I followed them when consciousness suddenly came to me, I remembered that the name Onii-chan called by them was also named Silver Blaze!

As I followed the two sisters, soon we reached the hallway and to the main door, I saw the door opened and the guards surrounding someone, he said, I can't anxiously see the person called Silver Blaze because he is currently surrounded. .

Before I could even tell the guards to step aside, the black and white sisters dashed forward at incredible speed throwing the guards out of the way as they hugged the word 'Man'.

Then I heard Shirone talking "Silver onii-chan why we've just come now we miss you so much" while hugging 'Human'.

"Yes, you said you would always come to visit us," Kuroka said angrily as she hugged the 'Human.

"Sorry, something's popping up, and I'm busy so I can just come over now, I'll make it up to you two and stay here for a bit" said 'Man' named Silver.

"Can I?" she asked as she put Shirone and Kuroka out of her arms as she looked at me with questioning eyes.

'Now I can finally see his face' I thought to myself. But, looking at her face confused me and barely able to speak but still could weakly mutter: "Yyy-ya, yy-you ca-ca-can s-hold as long as aa-who you like, yy-you ca-can, m-mo-more l-like ppp-please s-stay hh-here ff-for-forever!"

When he heard me he smiled, it worked! I almost fainted, so I ran away as fast as I could, I don't even know why I even ran away but one thing is clear she is soooo

HANDSOME!!!
