"I am sorry for peeking at you all the time, nyaa! I won't tell anyone of your affair with the fallen angels and your naughty days with them, nyaa! So, can you let go of me, nyaa?" 

She had a voluptuous figure and large breasts that appeared so full that they almost spilled out from her loose-fitting black kimono, which she wore on her body in a way that showed her round, white shoulders, and long, fleshy thighs that appeared so delicious. 

Her face was beautiful with long, black hair, which she tied in a way that showed her slender nape, yet the most unique part of her features would be her hazel-gold eyes with cat-like pupils, pair of black cat ears, and two black tails, which she swayed in a lazy, yet sexy way. 

"Do you think I will let go of an SS-Class Stray Devil like you, Kuroka?" 

Yes, the one before him was one of the most powerful stray devils in history, Nekomata, Kuroka. At the same time, she was also the older sister of Koneko, the cute white-haired cat in Rias' group. 

"Why not, nyaa? You even let go of fallen angels, nyaa? Can you let go of a cute cat like me, nyaa? Or rather, what did you do, nyaa? What is this space, nyaa?!" 

Kuroka knew that devils had the technology that allowed them to create a virtual space to hold a Rating Game, but this was different, she thought. Moreover, if it was just such a virtual space, with her magic mastery, it would have been easy for her to escape, but somehow, this space was so confusing and messed up her senses when she tried to use her teleportation magic. 

Was this an illusion? 

Did she teleport forcefully to another place? 

Or was this an imaginary space created by Masa?

Yet, Kuroka knew that this was a troublesome opponent, especially when Masa could control the space, which made her realize that her chance to run away was as good as zero. 

If she wanted to escape, then she knew that she could only defeat Masa, but... could she? 

"Now, do you understand that curiosity killed the cat?" 

At that moment, Kuroka felt her entire body filled with intense fear, which caused all the parts of her body to tense, and she subconsciously threw a ball of energy blast to Masa. 

BOOOOOM!

'I got him!' 

Kuroka thought that Masa was hurt by her attack, but she widened her eyes as the ball of energy blast passed through Masa's body, which turned into a mist-like before it returned to normal. 

"Illusion?!" 

Matoi. 

This was the ninjutsu that Masa of Mahouka learned from Kokonoe Yakumo, which allowed him to create a body clone, which was impossible to find by his opponent. 

'Well, it isn't like it is omnipotent.' 

While this magic made it impossible for anyone to attack him as Masa had tricked their senses, causing his opponent to think his body clone was a real body, but if his opponents had a wide area of attack, he, who stood on the side of his body clone, hiding, remaining in a shroud, would be attacked. 

However, Masa had to say that this ninjutsu, or ancient magic, was great, which made him want to know the "Parade," the modern magic version of Matoi, which had become the advanced version of the "Matoi." 

Regardless, Kuroka didn't intend to give up, using her "Senjutsu" and "Ki" to detect Masa's presence and escape from this illusion, but unfortunately, it was all in vain. Masa was in front of her, and her senses told her that the body clone before her was the real Masa instead of a fake! 

"What are you, nyaa?! You are a devil, but why are you acting like a ninja, nyaa?!' 

Still, if she couldn't find him, she thought of using a wide area attack by creating a poisonous mist, which was her specialty and trademark, and also a trump card, which allowed her to defeat all of her opponents and keep live till now despite her status as the SS Rank Stray Devil! 

Only—

Crack! 

"—?!" 

Crackle!

The space cracked, and black-reddish lightning spread everywhere as a powerful impact brought her down. She was attacked, and her mind was instantly subdued, causing her to cower in fear and even cry. 

'What is he?! What is he?! What is he?!' 

Kuroka thought that it was quite interesting to peek at three fallen angels, who were caught by the leader of the fallen angels, Azazel, wondering why they were caught, but then she saw someone suddenly defeat this leader of the fallen angels, which made her dumbfounded and surprised. 

A strange desire was also born in her heart, but her cautious nature didn't allow her to start a straightforward approach, and she kept watching from the distance as she saw how amazing he was by taking down three bitchy fallen angels, especially Masa's front tail was just too... staggering. 

Yet, even if Masa was strong, his ability to detect his surroundings was quite limited, she thought, but it seemed he just toyed with her, waiting for Raynare, Mittlet, and Kalawarna to leave, then met her directly, which made her wanted to cry! 

Or, rather, she was already crying! 

"D-Don't kill me..." 

"Have you joined the Chaos Brigade?" 

"Ha?" 

As Kuroka showed confusion, Masa felt strange and then asked, "What are you doing here?" 

"I was just playing around, nyaa! I am just bored, so I thought of playing a prank on the little sisters of Lucifer and Leviathan, nyaa!" 

Kuroka was afraid that her little sister would be targeted, so she lied about why she came to Kuoh Town. 

Even though Rias and Sona were the governors of Kuoh City, it didn't mean that they had full control over this city. Many supernatural creatures were living in this place, and even the church was a property owned by heaven. Instead, even if they were a governor, their control over this city was akin to turf, like how a yakuza worked. 

So, Kuroka could enter this city as she wished to, especially when Rias and Sona weren't that powerful. 

Only, all of a sudden, Masa's body started to transform into his human-beast form, causing him to become even bigger, and he gained Nemean Leon features, especially with his hair that grew into a golden and platinum color that danced wildly. 

"..." 

Kuroka just stared at Masa for a while, blinking her cute eyes, clearly forgetting her fear as she started to feel a heat that started to capture her entire body, which caused her to squeeze her plump, healthy legs tightly, especially when she saw Masa had become much, much "bigger." 

"...wipe your drool." 

"Ah, um, sorry, nyaa!" 

Kuroka wiped her drool right away, then said, "I changed my mind, nyaa!" 

"What do you mean?" 

"I won't play with those little sisters of Lucifer and Leviathan anymore, nyaa!" 

"Why?" 

"They are too boring, nyaa!" 

"What are you planning to do, then?" 

"Well..." 

With her most seductive expression and pose, Kuroka asked sultrily, "Can we make a lot of kitty, nyaa?" 

"....." 

Masa fell silent as he lowered his gaze to the body of the woman who was almost completely exposed before him. 

"By the way, it's my first time, nyaa!" 

"It's my first time, too." 

"....." Kuroka. 

"Ah, w-wait! I-It's really my first time! Ah, oh~!" 

Yet, while Kuroka was flustered, she was glad somehow.
