"Character speaking to inner demon"

Inner demon

"Speaking in Japanese."

Chapter One.

Kagome POV

It's been four years since I fell into the well on my family's shrine and ended up in feudal Japan. The first year was rough, having never so much as touched a weapon before, but after a run in with Sesshomaru, that all changed. Sesshomaru decided that me fumbling my way through my mission was likely to get me killed and that "that would be a shame if this Sesshomaru could not succeed because of your lack of skill." Or so was said by mister icicle dildo shoved firmly in his ass believed. I have grown a lot in these past three years, not only have I lost all "baby fat", I've filled out in the chest and have actually stopped looking like the spitting image of Kikyo. My breasts bigger, my hips are slightly wider, and my hair is still not straight. I no longer run around in my school uniform, but that's for more than one reason actually. The first reason being that it really is a pain in the ass to run around and hike all the time in a short ass sailor uniform. The second being that after the first year my mother switched me to being homeschooled. It was easier to keep up on my assignments and actually graduate from high school that way. Now, I run around feudal Japan in a similar style armor as Sango's, but instead of the pink that she has for the protective gear, I have black and purple and black and navy blue. Much like Sango, I also wear kimonos to cover my armor when going from town to town. Not only was I trained by frosty the snow prick train me in weapons, hand to hand combat, and increased my speed and flexibility. He also saw to it that I was trained in all forms of my miko abilities. So I can use my reiki as a whip, similar to Sesshomaru's poison whip, create offensive and defensive barriers, write sutras, heal wounds, mix healing potions of all sorts, create reiki weapons and ammo, and many other miko abilities.

Some other things have changed in the past four years, I no longer have romantic feelings for Inuyasha, or Inubaka as I call him, I have adopted Shippo as my son, and been adopted as a sister by both Sesshomaru and Inuyasha through blood bonding. I may no longer love Inuyasha as a man, but that hasn't changed my caring about him. He might be an arrogant, loud mouthed, annoying, egotistical bastard, but he is my best friend and brother now. I will happily lay down my life for his in a heartbeat if he needed it. Oh and I got the rest of my soul back from Kikyo. You see, one night she decided that she no longer wanted to wander the earth as a half corpse and asked me to end her suffering. Of course I asked Inuyasha what he thought and he agreed that she deserved peace and swore that he would still help take revenge against Naraku in her place. Some things may have changed, but others haven't. For example Miroku is still a raging perv, Koga still flirts with me and calls me his woman, and Sango is still the closest thing I have to a sister. The biggest change of all is that I am the Alpha Female of the Silver Inu pack until Sesshomaru finds a permanent mate. He told me once that if he was desperate for an heir he could enter an agreement with a bitch, knock her up, and raise said heir without being formally mated. With my knowledge of the future and overall intelligence, I have also become his star general for his army. He decided to commission a portable portal between my time and the feudal era so that I can keep seeing them, until the time periods mesh completely.

As of a week ago, the battle with Naraku and his minions is officially over. Kanna and Kagura are still alive and switched to our side, playing double agent. Kagura even mated with one of Koga's wolf pack. It also turned out that I wasn't actually Kikyo's reincarnation, but the reincarnation of Midoriko herself. Since the jewel is completed and purified, I was visited by Midoriko's soul within the jewel. She explained everything out to me and I was given the choice of letting the jewel continue to be passed down through my family line in the first born female or taking the jewel into myself permanently and becoming the eternal protector of the jewel. I chose the second. In choosing, I became a hybrid of sorts. I am both full silver inu like my brother and Miko. The portal was officially taken from me and ended so that I could grow into my demon powers fully. I said goodbye to my family and told them that even though it would seem like hours to them, it would be the full 500 years for me.

Timeskip 500 years

It has been 500 years since I've seen my family, I had to make sure I showed up on the exact date to be sure nothing got messed up. I am now Kagome Taisho-Higarashi, I am Vice President of Taisho Industries' North American branch. Over the centuries I am still Sesshomaru's right hand woman. He never kept a permanent mate like he said, but he named it so that any male child I have would be named heir of his empire. Currently, Taisho Industries not only is a tech company, but we also own real estate firms all over the globe. I am fluent in every language possible both current and dead languages, my powers as a demoness have been completely mastered so that I can hide my demon form in the public eye, I have a masters in business, and I have multiple doctorates in anthropology and archeology. I have sent notice to my family and I'm moving them to my mansion in Beverly Hills, California. I also bought the land that the shrine is on so we never lose it. I hired about half a dozen workers to take over since grandpa's age is becoming an issue. An annoying buzz starts going off and I sigh instantly knowing it's Sesshomaru.

"Yes, Sesshy-kun, what can I do for you today?" I answer.

"What have I told you about calling me that blasted nickname, Miko." He responds and I giggle.

"When has that ever stopped me, my beloved brother. Now what do you need I'm busy?" I ask him again.

"Straight to the point, I like it. This Sesshomaru needs you to confirm the purchase of a building in Los Angeles it's bottom floor and penthouse is owned by one, Lucifer Morningstar. We will be it's new owners make sure you get him to sign the lease again with the same terms." He answers.

"Understood, I will take care of it." I respond and the call ends. I sigh, so much for our day off today. I think to myself and make my way to the office.

Lucifer POV

I heard from grapevine that things would be changing around here. I still own the premier night club in L.A, filled with as much debauchery as I can possibly handle., Maze is still my only real trusted companion, and I'm still refusing to return to Hell. The only change that I've heard of is that the land that my night club is on is now owned by some big corporation. I also heard that said corporation is being run by a woman and this has me highly intrigued. I know this isn't the dark ages and that women can run as much as a man, I wholeheartedly agree with that. However, it does not change that most higher ups are over privileged, old, wrinkled, white men, I smile. I simply cannot wait to meet this woman, I also am hoping that I can renegotiate my deal for the building by sweet talking or fucking this woman into submission. I smirk devilishly and take a sip of the amber colored liquid in my crystal glass, the burn from the whiskey is a welcome feeling compared to the overall numbness and boredom. I look over behind me remembering that I have two naked sluts in my bed behind me. I shake my head and text Maze to get them out of my bed while I get ready.

After taking a shower, getting dressed in my signature black suit with a blood red button up shirt, and eating brunch. I check the clock and see that the new landlady will be here in just under a half hours. I can feel the beast within lurking, it's telling me that something big is happening today, I just don't for the life of me know what that something is. I head downstairs to the club and instruct Maze with her responsibilities for the day, when I hear the open and close of the heavy glass door.

"Hello, Mister Morningstar. My name is Kagome Taisho, I am here to discuss the updated lease since Taisho Industries is now in control of the property." I hear in a sweet voice that sounds almost like an angel's. I should know, I was one.

"Well, good afternoon Ms. Taisho, Lucifer Morningstar, and please no need to use formalities. Please have a seat, can I get you something to drink?" I offer and turn. I can hear my beast growling in appreciation. The woman who walked in is wearing a black pencil skirt that ends just above the knee, with a slit up both sides that shows off her legs and hugs her curves. Her navy blue silk blouse, is modest yet sexy showing off that she has a sinful set of tits. Her inky blue-black hair is pulled up into a ponytail, showing off the creamy skin of her neck, and her beautiful eyes look like pools of melted chocolate.

"Thank you, Lucifer, and if I could have a sweetened iced tea with lemon that would be wonderful." She responds with a pleasant smile.

"It is my pleasure, do you mind if I call you Kagome?" I ask her and then her scent hits me. She's not human. I think and I can feel my eyes flash black for a moment in arousal.

"Yes, you can call me Kagome." She smirks playfully, almost as if she can tell what my thoughts are. "Now why don't we cut to the chase, Lucifer. As I'm pretty sure you can tell by the way your scent changed, you know that I'm not human and I can tell a few things from yours." She adds and I catch the playfulness in her gaze.

"Well, Darling Kagome, what pray tell can you pick up from me?" I ask and step towards her, stopping with maybe three inches of space between us. "And let me just say, you smell simply sinful." I purr in her ear.

"My, my Lucifer." She starts and wraps her arms around my neck and leans in flicking my earlobe with her tongue before whispering. "You say sinful and I say that is because we are both demons. Yet we are both divine." She finishes and bites my ear. Fuck me, I want her. I think before placing my hands on her waist.

"You're a demon? Yet I can tell you are not one of mine, for I am the actual Devil." I ask.

"You should know as well as any then, that the underworlds are separated. To answer your question, yes I am a demon. A Inu Yokai to be exact." She answers.

"Ah, that makes more sense." I state, noticing that we still haven't separated yet.

"I may be a dog demon, but I also have a little fox demon personality." She purrs in my ear. "And I would love to try you out for a few days." She adds and I groan.

"Let's get this paperwork done and you can come upstairs to my penthouse. I'll take you for a whirl." I smirk and she pulls back and reaches in her briefcase and slides a folder to me across the bar.

"This is your new lease, it has all the same points in it as the last one, but the name of the company has changed from the previous owner's to Taisho Industries. I have full authority to make changes as long as they are reasonable and just for your information your little 'tell me your inner desires' bit will not work on me since I am not a human." She states in a proper business tone. I love how she switched gears like that. Professional yet sexy, just my type. I smirk and look over the notes and see that she was telling the truth.

"I see, yes this looks exactly like the old lease, but with your name. Now I believe the insurance needs an update and if we can look over the mortgage price and see if we can make any adjustments." I state.

"Hm...not sure on that. You're getting this place for a bargain and not to mention that your income from the club is pretty decent, I know for sure you can afford it. I would be willing however to add some benefits and minor adjustments to the building itself to make the price more worthwhile if you'd like?" She offers.
