Reincarnated as a Oni

Chapter 14

(y/n)'s P.O.V!

I was sitting in a garden with Miku who wanted to do something relaxing with me so we headed here. Miku was sleeping with her head on my lap. I wasn't wearing my armor and she had a smile on her face which I noticed. I sighed thinking 'It's nice not having to fight anything.' Just as that thought came to me a loud roar was heard. Miku shot up and I said "Damn it!" I picked Miku up and got up before jumping up over the building landing in the center of the village. I put Miku down and said " Go to the usual place while I handle this." She shook her head and said "No. I refused to hide while you put your life in danger also Noboru-san. I won't hide anymore." I could see she was upset. I sighed and said "Fine but you don't like me killing so I want you to stay with Nobunaga." She nodded and everyone began running to us. I said "Nobunaga, take care of guarding Miku." She nods and I turned to the others and said " The rest of you take care of the stragglers or any... uninvited guests. They looked at me confused while I turned to see the demon king with an army. I sighed and said "I really can't catch a brake from these guys." I turned to Noboru and said "I'll handle this on my own." I turned to the demon king and said "I'm gonna enjoy ripping your army to shreds kill you once and for all!" I let out a roar and the sealed armor appeared behind me and began fusing with me. 

I charged at his army and began burning them with black green flames and my Totsuka blade encased in my blade and green flames.

Time skip! 3rd P.O.V!

Everyone watched in shock at the carnage the battle. (y/n) was standing in front of the demon king with a massive black aura only leaving the green parts of the armor visible. The view scared all that stood in front of him.

(y/n) disappeared from everyone's view and he grabbed the king by the throat. He threw him up into the air and jumped following him. (y/n) began throwing a barrage of punches and kicks. He spun on point and using the momentum his kicked him down to the ground with enough force to cause a crater. (y/n) speed towards him and stomped onto the demon kings chest hearing a sickening crack. (y/n) jumped back and landed sliding back while stopping. The king slowly stood up and asked "How are you so strong? I am the demon king and yet I'm still weaker than you. HOW!?" (y/n) coldly said "Make your peace, death draws near." He began walking towards the demon king while the demon king began backing up in fear. (y/n) disappeared and appeared swinging his Totsuka blade. As the blade passed through the demon kings neck and continued only stopping when (y/n)'s back was facing him. A shock wave soon fallowed and anything caught in the wave was cut in two." (y/n) sheathed his sword and said "Now your end has come and so shall your descendants." He walked to the head and grabbed it. (y/n) turned to the others and said "I shall return to the king and deal with this." (y/n) vanished in black and green shadows.

(y/n)'s P.O.V!

I appeared in the kings thrown room scaring everyone. I chucked to demon kings head into the center of the room shocking everyone. I looked down at my blade noticing it still had his blood on it. I said "The reward for slaying the demon king." They looked at me shocked until a soldier spat "Like hell the king would give you a reward like that. You don't deserve...!" I appeared in front of him and planted my foot in his gut causing him to cough out blood while passing out. I looked down at him and asked "Any one else want to say anything?" Everyone shook their heads. I looked at the king and he sighed saying "I knew it was only a matter of time before you killed the demon king therefore I made sure to make the arrangements before hand." He pulled out document and said "All you need to do is sign it." I walked to him and took the document reading it before signing. The king said "Welcome (y/n) (l/n) the second highest royal." Everyone began clapping while I said "I shall return to my village and if there are discussions needing my help call upon me."
