Nine Tails Of Pain (Neglected! Jinchuuriki! Male Reader x Highschool DxD)

Chapter 1

Y/n's POV

I was walking back to my shack, wood strapped onto my back as I needed some fire to cook dinner and to get myself warm. I was about 5 minutes from the shack when I felt fallen angels chakra. I sighned and made a genjutsu on myself so I was invisible, then I made a shadow clone which I told to go to shack like nothing happended.  When he got to a shack he was attacked by four fallen angels. When clone was dispelled, I attacked three of them with phoenix flower jutsu. They burned and screamed in pain and the last one looked at me surprised. I quickly grabbed him by throat and I glared at him

Me: "Who sent you!?" He didn't say anything and I just grabbed him tighter " I ASKED. WHO SENT YOU!?"  He tried saying something so I loosened my grip. 

FA: "K-Kokabiel... It was Kokabiel.." After he said that I snapped his neck.

I buried all the fallen angels in a hole I did with earth jutsu and as I was about to enter the house, I turned around. I looked into the woods and formed a rasengan in my hand.

Me: "State your buisness devil." I heard some wispers. I made my rasengan bigger. The impact could level a city. "If you don't want to end like those fallen ones, I suggest you show yourself, both of you."

Just as I was about to send the rasengan into those two, they got out and my eyes laid on a beautifull red-haired woman with blue eyes wearing an armor and a grey-haired maid with red eyes.

Me: "What do you need devils? You  both seem quite stong. You might cause me to use my sacred gear."

Redhair: "Excuse us for our incompetence. My name is Sirzechsa Lucifer. I'm one of the devil kings and this is my best friend and my queen, Grayfia Lucifage." They both bowed to me and made me feel unease.

Me: "Excuse my rudeness then Lady Lucifer, it's quite hard to guess people you don't know just by chakra signature." I bowed myself and after I stood up I looked at Sirzechsa "So what did I do to make myself know around Maous?"

She simply shrugged and Grayfia finally took voice

Grayfia: "Lady Lucifer would need your help mister L/n." So they know my name? "Lady Rias, sister of Sirzechsa is tangled in a marriage with another high class devil. Her peerage is too weak to defend their master. Would you help us?"

I looked at Sirzechsa and her face had a wicked smile on it.

Me: "I'm guessing I won't train them. I guess you want me to fight for her, am I right?" Sirzechsa just nodded, while I had to think for a bit. "If you'd excuse me, come to the shack. It's not much but you can wait there while I make my decision." I got inside and  left the door opened

I sat at my bed, thinking about it, I was trying to see all pros and cons, that's when Kurama decided to speak

Kurama: 'Oi! Why would you say I'm a fucking sacred gear!?'

Me: "Oh shut up. We both don't know what they would say about a fucking tailed beast sealed in me." I faceplamed. First devils now him. "Listen you goddamn furball, I need your help. What should I do?"

Kurama: ' Say we go there, beat the living shit out of whoever wants this girl and then we get some money, maybe a better house and a favour from devils. Whadda ya say?' I smiled brightly and nodded.

I came downstairs and I saw Sirzechsa and Grayfia, sitting at a table having a silent conversation.

Me: "I've made my mind." I said announcing my position. They both looked at me and I smiled at them "Who will I fight?"

Next day, Underworld 3rd POV

Devils, high and low class were gathered in a wedding hall, on a platform stood a blonde man in a suit and a red-haired teen girl in a wedding dress. After even the red dragon emperor's balance breaker failed, it was clear that the wedding will finally complete.

Priest: "Now, Lady Rias Gremory, do you take Riser Phenex as your husba-" The priest was cut off by a explosion that blown the door.

Y/n: "You got shitty gurards, Zechsy. The fallen ones in the forest had higher potential of dealing with me." Said young man with (H/c) hair as he got inside, flicking dust off his outfit

Riser: "Who are you!? How dare you interrupt Riser's and Rias's wedding you low class-shit!?" said groom as he readied his fireball

Sirzechsa: "That would be me. It was clear that the fight wasn't fair, and it just so happens Mr. L/n wishes to fight you. You'd like to wager, right Y/n?" Devil queen said as she stood next to her younger sister that looked like her twin

Y/n: "That's right Zechsy. Riser! If you win, I will be in your power. You'll be my master and I will be a marionette in your hands." the groom smiled widely, yet Y/n smiled as well. His eyes became red with black slits (Think of Naruto's Kurama version 1 eyes) and a red racoon shaped pigmentation around his eyes (Think of Naruto's Sage mode pigmentation) as he enters Fox Sage Mode, raising his chakra to enormous levels "Yet if I win, I want Rias Gremory to have a choice of who'll she marry, no matter of race, status in royality or power. And the second thing we talked about Zechsy." He said, winking at the red-haired ladies gaining blush from both bride and the devil queen.

Sirzechsa: "Very well, do you accept the challenge, Riser?" the groom just nodded as he untied his tie a bit. "Then let the battle begin!" After those words, she stuck her hands towards two opponnents, as magic circles appeared below them.

Both Y/n and Riser were on the arena, staring at each other. The devils of all kind were whispering around each other about who'd win. Most of them agreed that whoever is fighting Riser will be deafeated.

I'm back with a cliffhanger! What will happen next? I dunno. Wanna find out?
