death becomes a NEET (the devils a part timer fan fiction)

I continued to walk down the quiet sidewalk. The only light I could see was the lamps on the empty street. Its pretty cold night. But what do I care, never did. When I came out of my little gaze I realized I had hyousukes blood on my palm. Gross. Idiot blood. I whipped it off on my pitch black hoodie and realized where I was. I was right next to maous apartment building. Maybe I should visit the demon group and tell them the job is done. When I was walking up the stairs I heard emi screaming. As usual she can't learn to leave them alone. When I was about to knock on the apartment door I heard more yelling. "SIRE!!! WHAT ARE YOU DOING!!!" "MR MAOU, MS EMI PLEASE STOP!" Chihos voice. Hm what are the devil and the hero doing now. I knocked on the door and twisted the door knob. Unlocked. "Yo maou..." When I walked in I saw emi,maou strangling each other and ashyia and chiho trying to separate them. And in the back urushihara on his laptop of course. "Am I interrupting something?" I asked in a calm voice. "Oh Miyako! No your not intruding please come in. Now if you would please get of me emi!" Emi got off and ashyia and chiho did the same. "Ok. I need to tell all of you something." I said as I took off my shoes. That got everyones attention. Even urushiharas. "Oh ok. Tell us." Should I in front of chiho. "So you know the guy causing the unknown deaths?" Everyone was staring at me at this point. "Um yeah. Wait did you find out who this guy is?" "Yep took care of it." Everyone looked puzzled. "What did you do?" Asked emi. Idiot what does she think I did. "Killed him of course. Actually more like destroy his soul." They gave me blank stares. "Woah you did? Nice now we won't have to look over our shoulders anymore. Who was it anyway?" Maou seemed glad. "Um old friend of mine." I looked over to see a purple eye staring at my hand. It still had blood on it. I quickly his it under my hoodie sleeve. "So how did that guy do it? Like did you say white stuff coming out of their mouths?" I looked up. "Yeah. He was using dark magic on his scythe blade. If it were to come in contact with any soul including demons and angels and even reapers their souls would no longer exist. But stealing the souls wavelengths." He learned that from me... I looked down at the floor. "I noticed he was using demon magic too." Maou,ashyia and urushihara all looked shocked. "W-What do you mean demon magic?" Ashiya was pale white. Almost as pale as me. "Did he steal demons souls too?" I looked up. "Most likely. His next target would have been me and my dad. My next guess it would be all of yours." "W-Well I'm glad you took care of it." "Yeah no kidding." Urushihara awkwardly said. Thats probably the first time I've heard him talk. I just remembered chiho was here. Does she even know maou is the king of demons? Probably. Shes probably clueless about what I'm talking about. I got up and walked close to the door and put my shoes on. "I guess I'll head ou-" I was cut off by maou. "Hey miyako... If you want you can stay a little longer. If you want." Chiho looked up with her big eyes. "Yeah you don't have to go yet." Stay? "Um.. Ok"
