30 - Couldn't think of a title

" So how is me going to school going to prevent a potential war?" Giyu asked

"Well you see, I have recently found out about a high schooler who might have a potentially dangerous sacred gear" Azazel said as he explained.

"So basically I sent out a random team of low level fallen angels to watch him in case anything happens but..." Azazel said as he sighed

"But what? Can you just tell me already" Giyu said. 'I already know this shit, just hurry up and spit it out bruh' He thought inwardly

"Well, after investigating the team's former exploits uh- they might have misunderstood my orders" Azazel said.

"...Misunderstood?" Giyu asked

"Basically, I was informed that the group I assigned, originally normally took orders from Kokobiel. And when he asks them to 'watch' a potential sacred gear user he means to get rid of them" Azazel said

"..." Giyu looked at Azazel for a few seconds before he responded "So what you mean to tell me is that you accidently ordered them to kill a high schooler?"

"Uh Yeah" Azazel said embarrassed.

"And this could lead to war how exactly?" He asked

"Well, the place I sent them to is Kuoh Town, in Japan. Which just so happens to be control of two of the current Devil King's little sisters" Azazel said sighing.

"*sigh* of course they are. And if the devils find out fallen angels killed a potential peerage member, this might get complicated" Giyu said

"Exactly" Azazel answered

"Fine, I'll do it" Giyu said.

"Great. I already have your papers done, also do you want Kalawarner to come? I can change some stuff to make it seem like she's a student teacher looking to practice teaching at the same school you are going to attend" Azazel said.

"I don't know it's up to her really" Giyu said "Anyway, tell me about this sacred gear. Got any leads on it?"

"Yeah, the reason being that it's a dragon type sacred gear. So you can see the potential of it already." Azazel said until his mood changed "*sigh* the thing is, the person who has it is just a huge disappointment. The high schooler is weak, his magic power can't compare to an infant, and he thinks with his dick too"

"Ah, a pervert with a dragon type sacred gear huh. But what if it's a twice critical? Or the boosted gear?" Giyu asked

"You underestimate sacred gears, Giyu. Every sacred gear is powerful if used correctly, after all they were given by god as a sort of protection from the other races, even the twice critical. Let's say my physical capabilities or magical capabilities are that of the strongest ultimate class. If I were to double all those attributes then wouldn't I be Super-class?" Azazel said "And as for the boy having the boosted gear... it's impossible, he is just too pitiful. We could barely sense he even had sacred gear"

"Who knows, he might just have it" Giyu said with a smirk 'Well I might just take it for myself to study' Giyu thought. In a way the boosted gear seemed somewhat in tune with the nine tails. The nine tails, even with half it's chakra is seemingly near infinite, combining that with a potentially infinite source of power a.k.a the boosted gear. Who knows what the result will yield, but then again he doesn't actually want the boosted gear, but just the concept of it's boosting capabilities.

"Well anyway, I'll leave it to you. I would tell you to be careful but... let's be real here the sisters of the demon kings are weak. They are only called high class because of their noble blood, at most they should be mid-class. Anyway you start next week" Azazel said as he waved him goodbye.

Giyu only nodded before he disappeared in a swirl of space. He went back to his own apartment after that, he needed to ask if Kalawarner wanted to come with him after all.

[Kyoto]

" So, you are going to attend a human school?" The blonde curvaceous woman spoke. This woman was the current head of the Kyoto Youkai Faction, Yasaka.

"Yeah, it's something that could potentially risk a war between the Grigori and Devils. Considering how Grigori is now in the Underworld instead of Heaven, you can most likely guess it could escalate rather quickly. Especially since we have that warmonger, Kokobiel. Although he has lost some of his power in Grigori his influence over the fallen is still as strong as ever" Giyu explained.

"Oh my. A war, that is quite serious" Yasaka said shocked

"Yeah, anyway since our factions are now allied, Azazel thought it would be best to inform you about this. After all if it really does spark a war then as our allies your faction would most likely be caught up in it" Giyu spoke

"..." Meanwhile Yasaka hearing this showed a worried expression. After all her faction was quite weak, and if they do enter a war. There is no doubt that they would suffer massive losses, she doesn't want her daughter to experience such a thing.

"Don't worry. This is the worst case scenario, but there is little chance of that happening. After all the little sisters of the devil kings most likely came to the human world to have a taste of freedom in exchange for governing their assigned area." He explained

"If they were met with any problems they would probably try to fix it themselves instead of asking their siblings for help as to show that they can be independent." Giyu said "After all, most likely if they fail to govern their area. They will be sent back to the Underworld. So if anything, they would first hide the problem from their siblings"

But even though Giyu said that she still looked worried. He sighed as he told her. "Once again don't worry, this is after all my mission. I will do my best"

"...Alright" She said

After that Giyu stood up and said "Well, that will be all for today. Farewell lady Yasaka, I'll do my best on my part"

"Onii-san!" But just before he could leave a yellow blur sprinted towards him. Of course he saw Giyu saw this so he opened up his arms and caught the blur.

"Oh, Kunou. Looks like you are doing quite well" Giyu said as he smiled

"No fair! Why didn't you tell me you were here. When I woke up, I felt your aura so I rushed here" She said as she pouted

"Sorry, sorry. I'll make it up to you okay?" Giyu said which instantly made the kitsune smile brightly

"Then you have to spend time with me for a full day! While also showing me cool techniques!" She said with stars in her eyes.

"Yes Yes. But unfortunately not today. I have something to do, so next time alright?" He said

"Mmm, fine! But you have to show me more cool techniques!" She said

"Of course princess!" Giyu said as he put her down. "Well then, I must be going now. Behave yourself Kunou, bye Lady Yasaka!" he said as he waved at them one last time before he vanished.

Once he left, Kunou turned around to look at her mom and said "Ne ne, Kaa-san when will Onii-san be my new daddy! Just tell him already!" Kunou said earning a blush from Yasaka.

The past 7 to 8 months, Giyu would sometimes visit as he promised. Somehow along those times he spent here, Yasaka had somehow fallen for him. In fact she didn't know how she fell in love with him in the first place. Was it because he save her daughter? Or his soothing and comfortable presence and chakra? Or was it something else?

{a/n: holy shit, to the guy who said he didn't like it when authors do a timeskip and suddenly the character fall in love and say it happened off screen

I'm sorry my guy, I became that kind of author}

Fortunately it seemed that Giyu hadn't noticed her feelings when he visits. But unfortunately it seemed that Giyu also didn't hold any feeling for her and only saw her as a friend. But she knew he already had a lover which somewhat ached her heart when she sees them together. Though she wouldn't mind if he asked her to be her mistress as it was normal for a powerful man to have a harem in the supernatural world.

She only sighed as she shook those thoughts out of her head. She needed to prepare for a potential war after all.

a/n:

Just because I tried to make the romance between one girl and the mc genuine by focusing on said girl for a long time doesn't mean it's not a harem ;)

I just don't want the romance to be shit is all. Like come on guys, girls falling for him in like one chapter? Nah bro u need some build up on ur life. but it does get pretty boring if I focus on one girl too much, so I'll try to quicken it up next time but not like one chapter fast...

As for the harem members... hehehe

Now as you already couldn't tell. He is gonna take the boosted gear, it won. By like alot of votes...

though i might plan on him not keeping it, just taking it from the pervert named issei hyoudou. He might give draig a new body and make him his familiar... idk still working on it

originally i was going to do you all dirty and do a 360 mindfuck by genderbending issei but I was like nvm.
