Rainy Days

Many weeks passed and the start of school is only around the corner for Rinku.

Today, Rinku was inside with his family since it's raining because of a typhoon. All of the family are inside the house watching tv drinking hotchoco.

Which was a cozy way to do when it's raining and cold. But Konata is getting bored, she wants to play outside but can't since it's raining.

Noticing her dilemma, Rinku thinks for a few second before saying; "Hey Konata, you want to do some rainy day activities with me?"

"Huh? What's that onii chan?"

"Well, it's what you do when it's raining and you don't have anything to do because of boredom. We can make a pillow fort out of pillows and blankets, or play house with it."

"So, do you want to play?"

Hearing Rinku talked, Sojiro heard what there talking about and he doesn't want to be left out of it. He joined the two of them for every activity and games they play.

Seeing them having fun, Kanata smiles and look at them lovingly. Noticing that the three of them are looking at her smilingly she made a questioning face.

Not long, she was also dragged by them to play. She of course didn't argue and she join in on the fun.

Looking at them, they look like a loving family inside the small pillow fort. Laughing and smiling.

...

After the playing, the rain isn't stopping at all and it's still pouring rain outside. Konata was already down for the count and already sleeping at the pillow fort they made.

Kanata was already in the kitchen to cook a meal for the family, leaving Rinku and Sojiro playing a card game with each other.

After playing with his dad, Kanata called them to eat. Waking up his little sister they proceed to eat.

...

Entering his room, Rinku was going inside the time chamber to sleep a year for his improve his mana. Leaving behind his clone in sleeping position Rinku was going to enter but suddenly Sistene said something.

[Rinku the phone inside your inventory is ringing, it's from Azazel.]

"What now..." taking out his phone, he answered the call and said; "What up? Aha... Ok... that's it? Nothing more?" ending the call Rinku was stupefy for a bit and just forgetting what that guy said to him.

Continued entering the time chamber, the first thing he saw was the two people training. Two girls exchanging blow for blow, the other one was a older girl who have black hair and the younger one has white hair both of them have cat ears.

Noticing his sudden appearance they both stop and rushed towards where Rinku was.

"Rin-chan did you come here to visit your Onee-san~?" the older one asked.

Giving Rinku a small kiss in the cheeks.

"Onee-chan don't tease Rin Nii-chan." the younger one tried to protect the him from her older sister.

The two of them are Koneko and Kuroka, the nekomata sisters. Both of them are Nekoshou, a rare species of Nekomata.

...

One day, when Rinku visits the underworld with Azazel. He explored the place by himself, unnoticed by everyone and when he passed at the branch family of the Naberius House. He suddenly remembered that the place is where the Naberius House's branch family experiments people at and of course the nekomata sister.

So he sneaks in and take a look, if possible he wants to sneak them out of the place but something unexpected happens. That day was the day Kuroka become enraged and kill his master.

Because of the chaos that was happening he successfully finds where Koneko is being held because all the family are trying to fight Kuroka who was rampaging becoming the focus of everybody.

Entering the room, he saw the unconscious Koneko strap on a contraption for experimentation. Taking her out and caring her out unnoticed. Then Rinku takes a look at Kuroka who was rampaging in rage and those Naberius people running for there life.

Since they can't stop her they where forced to run. Seeing them run away, Rinku moves behind Kuroka. When Kuroka felt someone was behind her, she was going to attack it but she wasn't fast enough because Rinku already chop her back of her neck and fainted.

Carrying both of them, Rinku escaped without them knowing.

Because of that Kuroka became a Stray Devil and now they both living in the human world with Rinku. They train mostly inside the time chamber but when they where out they are in there cat form playing with Konata.

Rinku also tried to erase the side effect of there nekomata traits of "mating in heat" since it will be troublesome if he was not around and they become in heat for some reason. Not that he like it to be him but, you know... you get my point.

But Kuroka said that it's fine, that she can control herself even when she's in heat. But for Koneko, she might not.

But Koneko also didn't want to erase her trait, so Kuroka trains her sometimes about control. While he tried to make a candy that have the effect of a aphrodisiac for Koneko's training of controlling herself when in heat.

Of course Rinku was there if they we're going to do that. He was there to cancel the effect of the candy, but Kuroka asked if he can make a cure for that so he can relaxed even when they do it themselves.

So now she can control herself even when in heat.

...

"Why are you here Rin nii-chan? Koneko asked.

"I'm just going to sleep for a year inside here to boost my power a bit."

Kuroka looks at him enviously and said; "I'm still envious of your powers until now. You just need to sleep to boost you power Rin-chan~."

"Well what can I do? I'm just to awesome."

"Narcissist!"

"Narcissist."

"Well at least I'm not a pervert."

"At least not for now." Kuroka smile knowingly.

Rinku shivers when he caught the look in her eyes.
