Ohayo everyone, I'm gonna try writing a new story based on an anime I recently finished watching the available episodes for. So let's get to it!

Mastering the Challenge Chapter 1: A new challenge

Demon world… a dangerous and vicious place. Demons get killed every day because they step out of line with others. I should know since I make the rules for the demons. I'm Wolf, a territory, boss of the west side demon world. I've broken a few necks a few times around because they try to cross me and take my head. In this world, when you're a boss, if a demon kills you, they become the boss of the territory he ruled before. No one's ever beaten me before.

The days were long in my part of the demon world. Things went slow and chilled as always. I had no worries at all; I was more layed back right now especially since Staz passed through earlier just to give me a good fight. I didn't even have to worry.

My underlings followed me around like strays after a human being. It was good to finally get some alone time for once. I relaxed into my house which was rich like, long couch close by fireplace and few bedrooms and a bath.

For once I was gonna take it easy… I sighed as I relaxed on the couch about to watch something when my phone buzzed in my pocket. I looked at it; Kazu's name came up, another underling. "Moshi mosh?" I said trying not to sound too annoyed.

"Wolf-sama… we got a problem down town." Ugh what was it now? Another demon trying to kill my ass? "What is it this time? If it's a fight I'll leave it to you guys." I just looked at the half eaten food on my plate I was snacking on earlier.

Kazu was talking to a few others in the background before he got back to me. "It's a human girl, sir. She's actually fighting back against the demons!" I heard screams on the other end and a female shouting and then a minute later, total silence. "Kazu? What's going on?!" I yelled into the phone. Kazu stammered. "She almost killed everyone, sir. I think you should come down before someone gets killed." Something snapped in my mind. There's no way a human girl can fight off demons and still be standing! I think as I run out the door dropping my phone on the way out.

? POV

"Who's next?!" I hissed in rage. These idiots were wasting my time. Demons… That's all they were. Heartless bastards that should all die. I stepped on one of the guys as I listened to the wind blowing my sword ready at my side. I turn around to see the demons part down a row to reveal a white haired, tan skinned, golden eyed demon. He wore a grey and white striped shirt with white pants.

"You must be the human girl I heard about." I cracked a smile. "I got no time to play with a child like you." I grinned at his cockiness. He clapped his hands. "I just want to congratulate the first person to take out almost 1/4 of my demon underlings. Nice job human. Or would you rather give me your name so I can greet you properly."

I grinned at him. "Katana. Katana Ookami. That is my name. Learn it well, Wolf-boy." I put my sword away as I turned and walked away from the scattered group of pathetic demons. "Where do you think you're going?" I called out.

Wolf's POV

I stared at the back of the bright orange haired girl who looked as if she had red streaks in it. Her shirt was teared badly to show part of her chest and back and her jeans were torn in a few places. Her shoes were just as bad, covered in demon blood. Her chest looked like a size D but I couldn't tell from this much distance away.

She turned to me once more where the front of her face showed more of the red streaks than the front did. Her silver/grey eyes pierced mine as her average pretty girl face smiled. She was tall but not lanky. She was a good build on muscle but not overdone. She had long legs which added to her height mostly and she was the good kind of skinny. She had a black choker with a red realistic heart made out of metal on a black chain connecting to the choker itself she had leather wristbands on her upper arm and right wrist and had a green sheath that held her steel sword she just put away moments ago. It was connect by a belt on her pants.

"Nani? What's it to you where I go, Wolf-boy?" She murmured as she crossed her arms over her big chest. I tried my hardest not to look at her breast while I talked. "This is my territory, meaning you entered this world on my turf now you're my problem. So in any case you're stuck with me."

Her eyes widen and before I even knew it she was in front of me her hand on my neck with her other hold the sword to it. "Speak, you good for nothing beast! Am I really stuck in this part of the world?!" her anger just made me laugh. I never had a challenge like her before. "Yes, you're stuck in my care for now."

She growled and when I growled back, she tossed me aside before sheathing her sword again and glared at me. A light blush was on her face. She is gonna be fun to mess with. I thought as I helped a few of my underlings up. The ones who got up carried everyone else to the doctor to patch them up.

Before everyone left Katana spoke. "Gomen." Kazu looked at her and gave her thumbs up. "Nice job, only Wolf-sama was able to do that before, now we got two people who can beat us all down." Kazu smiled before carting off another demon.

"That's your name?" She asked looking at me. "Werewolf named Wolf…. Not very creative I see…" My eyes widen before I grinned blushed a second before saying. "Urusai. And being name Katana wasn't bad? Isn't that a sword?" I laughed as she blushed and stammered. "My last name means wolf…" She looked away.

"I gave it to myself after my family died. Thanks to you demons of course!" My gaze snaps to her in time to see a trickle of tear rolled down her face. So I'm not the only one with a sad past, I thought as I lead her back to my place.

Katana's POV

"Sugoi, Wolf-sama!" I cried out when he opened the door to his place. It was a beauty of a living room. Wolf looked at me in a weird way. "'Wolf-sama'? No, you don't have to call me that. Just Wolf. Or Wolf-kun." He spoke as he picked up a plate and went to the kitchen to put it away.

"Come in, take your shoes off and sit. I'll take ur shoes to scrub the blood out." He looked back at me over the kitchen counter. "Eh, you might need new clothes too. I can see your bra." I blushed bright red. "Teme!" I glared at him as he led me to his room. "Go take a bath and the clothes will be outside the door. When you finish undressing, put ur clothes outside the door so I can wash them."

I did mostly of what he said and just kept my underwear. I scrubbed every part of me that wasn't even covered in blood. I heard a knock on the door and Wolf's voice came through. "Katana, your clothes are out here by the door get them when you're done. I'm gonna go scrub your shoes now." He walked off as I turned off the bath and got out to see what he left me.

I saw a shirt with a familiar design similar to a rock concert t-shirt and tight boxer shorts. They felt snug but it would have to do. The shirt was a bit baggy. Shit, I just remembered I left my bra in my torn shirt. Can today get any worse?

Wolf's POV

I hit the jackpot. Her bra is still in the shirt. Damn she is a Size D! Sweet. I shook my head. I sound like a horny mutt! Get it together, Wolf. She's just a human. I gotta look out for her till I can return her to the human world. I picked her shoes up from the front entrance and took them to the sink with a scrub brush as I tried to get the blood out of the shoes. It might not be so bad living with a human. At least I hope she doesn't kill me in my sleep.

Katana's POV

I came out of the bathroom and into the living room to see Wolf scrubbing the blood from my shoes as I relaxed on the couch and took a nap. Hope he doesn't kill me in my sleep but I'll take that chance for now. My head landed on the couch as I rested.

Wolf's POV

She had a rough day. I listened to Katana's silent and slow breathing as I continued to scrub the shoes till they were back to being brown. Her boots looked a bit better but since most of the blood caked already I can't do much for it.

I took a plate of food and sat it next to her when she woke up as I went and took a bath. I stretched my arms out before looking down at her again. She was a pretty cute human, but her manners are uncouth. Speak for myself I have the worst manners possible…

Going to stop there for now, I think that's a good start for a new story what do you guys think? All in one night, hooray for me XD gonna go to sleep now, night~ XD
