"This is Kuroka. She is my knight." 

"Nice to meet you, nyaa~!" 

"Nice to meet you, Kuroka-san." 

While Asia greeted Kuroka politely, Serafall and Ravel remained in silence. 

"What's wrong? Do you have something to talk about?" 

"...Masa, I know that it might be weird, but isn't Kuroka a stray devil?" 

"Yes." 

"..." 3x

Not only Ravel and Serafall but also Asia were shocked when they heard Masa's words. After all, she had stayed in the Underworld and learned many things, so of course, she knew what a stray devil was. 

Watching their reactions, Kuroka felt that it was normal. Instead, she wondered what Masa would do since she knew well that those three must be his women, and considering her status, she knew that they would reject her. She tried telling him to stop his decision, but it was all fine; she thought since what she needed was only Masa. 

Still—

'His woman is really a Leviathan...' 

Naturally, Kuroka knew the strongest female devil in the world, yet unexpectedly, Serafall was really Masa's woman, which amazed her inwardly. Still, when she thought of Masa's large size and ability, her beautiful face flushed, understanding why even Serafall fell toward him. 

Regardless, she knew well that she wouldn't be welcomed by his women after they knew her identity, but—

"Cute~! Kuroka-chan is so cute~! Can I touch your ears and tail~? Can I~?" 

Serafall made a strange gesture with her hands as she was ready to touch Kuroka's cat ears and tails. 

"....." Kuroka. 

"Nice to meet you, Kuroka-san. My name is Ravel Phenex, and I am Masa's fiancee. I hope that we can support him together, okay?" 

While Serafall appeared childish, Ravel had entered the role of Masa's future wife and solemnly told Kuroka to support Masa together. 

"..." 

Nevertheless, Kuroka was surprised by their reaction, and she didn't say anything, even if Serafall started to rub her two tails and cat ears. 

"Hnh~!" 

"....." Everyone. 

"Sorry~! Sorry~! I never knew that your ears and tail are your sensitive parts." 

As Serafall apologized, Kuroka was embarrassed for leaking such a voice, but she couldn't help but ask, "You are okay with me being his peerage member, nyaa?" As she came to Masa's place, she also realized how amazing Masa's identity was. For a criminal like her, was there a place to be by his side? 

"Of course." 3x

Whether it was Serafall, Ravel, or Asia, they had no doubt about Masa since they knew well that he wouldn't do something that would endanger himself, and if Kuroka was his choice, then they would support him. 

More importantly, whether it was Serafall or Ravel knew well that the life of the reincarnated devils in the Underworld wasn't all rainbows, and a devil-like Masa, Serafall, Ravel, Rias, and even Sirzech were rare, so they knew well that the stray devil became one due to their masters instead of their own wishes.

However, as Masa, Serafall, and Ravel were devils, even if those devils were wrong, they had to support the rule of hunting down the stray devil since if they didn't, it would affect their ruler over the Underworld. 

As they had said before, the society of the devil was feudalism, so all the higher positions supported each other to maintain their status. 

Still, if Masa wished to get Kuroka, then it didn't matter since who could stop him from making his choice? 

"...." 

While Kuroka felt weird inwardly, her eyes slightly reddened before she hid behind Masa, feeling quite embarrassed, and at the same time, she didn't want her crying face to be seen as it would affect her cool and elegant persona. 

"....." Masa. 

'So... it's okay to trust him, right?' 

Trust. 

Having been betrayed by her master in the past and hunted by devils, it was impossible for her to give her trust so easily, and learning "Senjutsu," the cursed power that was feared by her little sister and others, would make the user learn the malice of the world, made her able to detect the negative emotions from others, yet she couldn't see that from everyone here. 

Masa and Serafall aside, they were so powerful that neither of them thought of Kuroka as their opponent. 

Ravel and Asia sincerely trusted Kuroka since Kuroka was someone that Masa had chosen, and as Masa had never betrayed their trust, they had chosen to believe his choice without hesitation. 

"But how did you meet her, Masa?" 

"Did you meet her in the Underworld?" 

Whether it was Ravel or Serafall, they were curious about how Masa met Kuroka and decided to make her into his knight. 

If so, then wasn't it dangerous since no one expected that a stray devil would exist nearby? 

If Kuroka was just a normal criminal, then it might be okay, but if she was part of the Old Satan Faction, the enemy of the devils, who wished to return the ruler of the original Satan, then Serafall thought that she needed to talk with Masa more. 

Yes, many hundreds of years had passed after the Devil Civil War between the Old Satan Faction and new factions within the Devil society, such as the Great King Faction and the New Satan Faction, of which Serafall was part. 

While Serafall could trust Masa, she wanted him to be careful since those from the Old Satan Faction weren't pushovers. 

Yet—

"No, I met her in Kuoh." 

"Kuoh?" 3x

The three were dumbfounded, then looked at Kuroka, who nodded. "Yup, nyaa~! I met Masa in the Kuoh, nyaa~!" 

"..." 3x

"...did you illegally teleport there?" 

"Yes." 

"..." 3x

Unless they had a special status, it was a crime to teleport to the human world without permission. 

If one wanted to go to the human world from the Underworld, one had to be like Masa, who went by a magic train that led them to the underground station of Kuoh town. 

"Why did you go there? If you go there, you should greet So-chan, right, Masa-chan?" 

Serafall moved closer, trying to sniff Masa's body, wondering whether she could smell the scent of her little sister on his body. If he also took her little sister, then... 

'Hmm~!' 

Serafall only lowered her head and didn't dare to think about it~! 

"....." 

Could Masa tell the truth? 

Still, Masa felt a little awkward about meeting Sona, and at the same time, how could he tell them that he just went there to save fallen angels? Fortunately, this naughty cat didn't say anything, only looked at him mischievously. 

"...did you make another woman in Kuoh town?" Ravel asked with a blank expression. 

"....." 

Taking a deep breath, Masa said, "Except for Kuroka, I didn't make another woman." He didn't lie since Raynare, Mittlet, and Kalawarna weren't women that he had made during his visit to Kuoh Town earlier. Instead, they had been his women for a while. 

Still, if peace between the devil and the fallen angel happened, then he wouldn't have to worry about his relationship with the three fallen angels, but unfortunately, such a peace hadn't arrived, and he knew if someone knew what he did, then he would be... labeled as a criminal. 

Or... a hero? 

Anyway, Masa felt that he didn't need to introduce those trio bitches, at least for now, and fortunately, he had a way to solve this problem. 

"Then?" 

"I am going to Kuoh to learn a unique knowledge." 

"Unique knowledge?" 

Masa didn't say anything and showed his new knowledge directly by making hand seals, which dumbfounded Serafall, Ravel, and Asia. Then—

"Bunshin." 

Masa suddenly split into two, creating a body clone, which was known as "Bunshin" in ninjutsu. 

Yes, Masa thought that the knowledge of Kokonoe Yakumo from the world of Mahouka really helped him solve this situation. 

Yet, similar to Kuroka, when Ravel, Serafall, and Asia saw Masa, who learned ninjutsu—

"Can I become a ninja, too, Masa (Masa-sama)?" 3x

Like any of those from Western, everyone loved a ninja. 

"Ah, me too, nyaa~!" 

Kuroka quickly joined in. 

However, while Masa and the others were happy with the new family member, the fallen angel group was in a panic, especially those cadres, the group of leaders among the Grigori. 

"...are you sure, Shemhazai?" 

"Yes." 

The Vice Governor General, Shemhazai, had a solemn expression as he faced all of his comrades. "Azazel passed away." 

At that moment, all of them knew well that all the fallen angels were about to face the greatest crisis in their lives.
