Chapter 1

Tsukino Usagi hums happily as she wanders through the Shinagawa ward of Tokyo where she sees what transpires to cause Okumura Rin to fight the pathetic punks that were deliberately hurting the area pigeon population. Usagi jumps right in as well since she had changed out of her school uniform into black shorts, a sapphire blue halter top, and she had on black and red tennis shoes. " Hey, Usa, decided to help me deal with some punks. "

" You always find good reasons to fight. Now, how would you like to help me deal with a pain in the ass demon in the area. "

Rin smirks, Usagi had broken the seal on his powers in such a way that he retained his human looks but could use the powers afforded him by his demonic heritage. He also happened to be a fully licensed demon hunter as well. This meant the Exorcist community couldn't touch him unless they wanted to go to war with the Emperor of Japan. " I'm always game, just let me head back to my most recent part time job. "

Usagi follows him at a more sedate pace, knowing she had pissed off several higher ranking individuals with snatching Okumura Rin up as a demon hunter. The Vatican was really going to be pissed when Rin's heritage became known but, demon hunters didn't give a damn. Rin curses under his breath when he realizes he got fired again, " Study to get into Crossroads Junior High. I could use someone that will actually help me study, then we can work towards high school together. I know you hate school, Rin, so do I, but it is necessary. "

Rin sighs but agrees to do so even as he follows her to deal with the demon, another one that the exorcists hadn't dealt with properly. That was the problem with exorcists they exorcised the demons yet hardly ever destroyed the problematic ones. This meant that the demon hunters had to go around and pick up after them. Rin knew he couldn't use his blue flames but, he could use his absurd strength for this fight. Usagi has just finished their most recent target off when she senses the danger to Rin. Without even thinking she interposes herself between him and the exorcists that had attacked him.

The blonde winces as the attacks make contact with her yet she holds her ground. Her sapphire eyes are alight with rage even as her aura becomes visible, " What the hell are you idiots thinking! He's a demon hunter. I will be lodging a formal complaint with the Emperor, you biased, hypocritical bastards. Most exorcists happen to have demonic blood. Plus we were cleaning another mess left by you idiots because you rarely destroy the problem demons, you just cleanse areas, seal them away, and leave us DEMON HUNTERS TO CLEAN UP AFTER YOU! "

The three exorcists present wince as her tirade crashes over them, they had interfered on an Albarn hunt, attacking an Albarn's partner, " Rin. "

Rin swings her up before leaping up onto the roof of the nearest building, then he roof hops away until they're in the Minato Ward. Rin sighs, " Usa-chan, where to next? "

Usagi tries to focus through the haze of pain traversing her body, now that they were relatively safe she had nothing to distract her from it. She was lucky she was still conscious actually. Light blue eyes look at her closely before the slightly older teen nips gently at her pulse point with just enough force to lightly draw blood. Normally his demonic half would be screaming at him to take, but Usagi was different. Usagi was viewed as their true other half which meant Rin was able to heal her after a love nip. In demonic culture they weren't true mates yet but, he had claimed her as his.

The blonde nearly wilts as the pain wracking her body disperses, " You need to work on your situational awareness, Rin. "

" I know, thank you but, dammit, try not to do that again. " Rin says.

" That was sheer instinct, my body moved before I gave the order, Rin. "

Rin was almost caught off guard when she kisses him, almost. Instead he shifts her to the point where she can wrap her legs around his waist, easily holding her up. Meeting Usagi had been the best thing to ever happen to him. Rin lets his mind drift even as he lays them on the roof as their make out session heats up.

Flashback:

Okumura Rin sulks as he walks through the Minato Ward with his class, he always tried to be a good big brother, a good person yet he was never good enough. Sure his dad and brother loved him, he knew that but they viewed him as an over violent screw up.

The navy haired and light blue eyed almost fourteen year old blinks when he's plowed over. Instinct had him cushioning the fall of the one whom had run into him. He finds himself looking into the purest sapphire blue eyes he had ever seen even filled with misery, " Sorry for bowling you over like that. "

Before the sapphire eyed girl could run off Rin gently grabs her wrist, " I'm Okumura Rin. "

" Tsukino Usagi. I really have to go, Okumura-san. "

" What's got you so upset that you're running blindly through the Juuban district of Minato anyhow? " Rin asks her.

Usagi blinks, " Why do you care? "

Rin curses internally at what that one question indicates about her life, " I can't stand to see such a pretty girl so upset. "

The blonde relaxes, " My parents hate me, hate the fact that my paternal grandmother chose me as her heiress…they hate the fact that I can barely keep my grades at the average level, that I refuse to act like a meek and defenseless child…"

Rin knew he would get in trouble for ditching his class, for once he didn't give a damn. He just walks around with Usagi, letting her vent her feelings. He didn't even realize that she had led him to her grandmother's home, changing his path in life from that moment forward.

End Flashback:

Rin had learned of his heritage through training to become a demon hunter, been taken to the weapons' smith Totosai to forge a weapon for himself, one that he wore as an amulet until he needed it. Instead of his powers being sealed his demon blood was now sealed since the Albarn family happened to have bits of his old man lying around. Notification of his demon hunting status would happen the next week. Learning that his own brother was being trained as an exorcist in order to keep an eye on him had hurt. Only the man whom raised him, Usagi, and her demon hunting family trusted him to do the right thing.

Usagi had never once pulled away from him, even when he discovered he actually happened to have a thing for blood. That first time he hadn't intended to break her skin, just nibble and suck long and hard enough to bruise. Instead they'd both discovered Rin happened to like the taste of blood, especially Usagi's blood, and that Usagi actually enjoyed what had happened, after she got over her shock. After that first time Rin took care to leave the bite marks where they wouldn't be readily visible on his girlfriend's body, which meant her hips, thighs, and breasts. His hands had already untied her halter top, shoving it aside just enough so he can bite down hard enough to draw blood.

He easily holds her still when she tries to arch her back, the quickening of her pulse telling him all he needed to know. He knew by now how she reacted to his loving bites, Usagi hadn't even realized that was one of her major turn ons until that first time he accidentally bit her harder than he meant to in just one make out session, in a dark alley to boot. Once he's lapped up all her blood and healed the bite mark over enough to no longer bleed he allows one hand to slip lower to finish her off. Learning that his girlfriend happened to be the reincarnation of the Princess of Earth's Moon had been stunning. Reading that book on Lunarian Physiology, particularly for the females, had been enlightening. After that he'd taken care to always see to her needs because if he was the one to heat her up only he could sate her lust. Otherwise she'd remain painfully aroused until he did something about it.

The strength that being half-demon afforded him was useful when it came to holding Usagi down, she was a helluva lot stronger than she looked. He'd been filled in on demon etiquette as well by the Kitsune Shippo. Shippo always looked oddly reminiscent around him as well. It wasn't until Usagi mentioned to Rin that he acted a lot like Inuyasha that he'd realized Shippo happened to be the same one whom had helped to take down Naraku once and for all. " Rin, quit teasing. "

It was her tone that told Rin that she was beyond ready for him to finish her off. The half-demon was quick to kiss her even as he sends her over the edge, Usagi could get loud. Kissing her would swallow down any vocalizations of her bliss. Rin rolls them over and cradles her in his arms, letting her system level out. Unlike her he could actually deal with certain problems on his own.

When Rin finally returns home to the monastery he lived in the fact that he kept his part time job is celebrated, " Let's get you patched up, Rin. "

Rin follows his twin Yukio off to their room so he can get cleaned up by his younger brother, " Where were you after work, Rin? "

" Well, after my last delivery there were these punks just shooting pigeons because it was fun so I put the fear of Susanoo into them with Usa-chan's help. Then she asked me to help her with a case of hers. "

Yukio blinks, " That's right, she's a demon hunter isn't she? "

" So am I, officially, starting next week. Usa-chan's grandmother trained me up. Three exorcists went after me then and Usa-chan instinctively got in the way, she read them the riot act, then asked me to get us out of there. Yes, I know we're both half-demon and that I inherited the lion's share of pops' power. However, the Albarn family got me a weapon that seals the demonic blood instead of my powers which was made up of some bits of our pop by the demon weapons' smith Totosai. Since I happen to be a demon hunter the Vatican and affiliates can't fuck with me unless they want the Emperor pissed off. " Rin says.

Yukio freezes, " Rin, I…"

" Save it, Yukio, I have always protected you, trusted you…to find out the same isn't true…I'll admit, it hurt, it still does actually. "

" How does Usagi feel about dating a half-demon? Plus, I became an exorcist to protect you, nii-chan. " Yukio asks.

Rin snorts, " That's probably one of her bigger turn ons, the fact that I can hold my own with her, am actually strong enough to keep her pinned, believe me she is much stronger than she looks, and more importantly I see her for who she is. I let her vent however she needs to, and she reciprocates for me. I have all the protection I need being the demon hunting partner to an Albarn Clan demon huntress. "

Rin is inwardly cackling at the fact that he made his little brother blush, " Demon hunters don't give a flying fuck about heritage, 'Kio. "

" I see, you actually don't need a job, do you? "

" No, I don't. Still, think you could help me get into Crossroads Junior High? Usa-chan needs someone whom can help her study. "

Yukio smiles, " I can do that, Rin. "

Juuban:

Usagi lounges in the tub even as she looks at the latest mark Rin had placed on her body. Her lunar blood didn't heal these marks as they gave pleasure and not pain. She knew why he refused to let her taste his blood yet, she was only fourteen after all. Her hanyou would only let that happen once she turned sixteen. Until then he kept his scent on her to warn other demons and hanyou's off from trying to take what happened to be his. Only when she imbibed his blood would she be considered his mate, at the moment she was his intended.

The blonde finishes her bath and puts her pajamas on, a t-shirt she had stolen from Rin and a pair of shorts. She'd placed a spell on the shirt to keep it smelling like Rin as well as keeping it clean. The next morning she's running late for school and stupidly saves a black cat from a bunch of little brats. A cat she knew all too well even as the reincarnated moon princess races off. She had just saved fucking Luna, great. Thankfully she just beat the bell and she manages to ignore her hunger to hold out until lunch. This meant that Haruna-sensei had no cause to hold her after school for detention. Plus, with Rin's help she had passed her test with a 92, it may not be Umino's grade but, still good enough.

Shinagawa Ward:

" Usagi-chan, why are we in Shinagawa? " Naru asks her best friend.

" You wanted to meet him, right? " Usagi asks her.

Naru freezes, " I finally get to meet your boyfriend? "

" You do, Naru-chan. " Usagi states and wends her way to the monastery, meeting the Okumura twins at the entrance.

" Usa-chan, hey. " Rin says, automatically pulling her to him.

She nestles into his embrace, " Miss me, Rin? "

" You have no idea, Usa-chan. Going to introduce me? "

" Okumura Rin, the brunette happens to be my best friend Osaka Naru. Naru-chan, this is the one you've been bugging me to meet. "

" How the hell did you get to him first, dammit, Usagi. " Naru asks her best friend because Rin was fucking hot.

Usagi snickers at this, " I literally plowed him over after another let's list everything we hate about our daughter day a couple of years ago, give or take. "

Naru sighs, " Why are the good ones always taken or gay, huh? "

" I do have an available twin brother. " Rin says, " Okumura Yukio. "

Yukio splutters even as he starts blushing, " Rin-nii! "

The kawaii squeal emerges at Yukio's reaction from Naru, causing Rin to snicker while Usagi just relaxes in his arms, " You know, 'Kio, you could give Naru-san a tour of our ward while Usa-chan and I head off. "

Naru latches on to Yukio before he could even think to protest even as Usagi and Rin take their leave. Rin is still cackling a block later, " Wasn't that a bit cruel, Rin? "

" Na, my bro needs to lighten up and loosen up. Why bring Naru to meet me now, Usa-chan? "

" I inadvertently saved Luna earlier. "

Rin groans, that meant the shit storm around his girlfriend was about to start up quite soon. " I also wanted Naru-chan away from her family's jewelry store. I've been sensing negative energies for the last couple of days. "

Rin understands what she's saying, " You know, you could have changed out of your uniform today, Usa-chan. It would make it so much easier for me to renew my scent upon you. " His mouth was right on top of her ear as he says this to her, his tongue darting out to lick the shell of her ear.

Usagi feels the shiver traverse her body, " Rin, you can play later, after we deal with whatever is going on at the Osaka family jewelry store. "

Rin pouts at this but follows his girlfriend back to her home district, he and Yukio had just come from Rin testing to get into Crossroads Junior High when he had spotted Usagi. Rin wasn't about to pass up an opportunity to spend time with her and then get in a hot and heavy make out session. Neither of the pair were expecting to get accosted by a certain black cat though, Usagi rolls her eyes, " Luna, Rin is a hanyou, I think he can handle talking animals. "

Once Luna gives Usagi her henshin item the reincarnated princess rolls her eyes before heading for OSA-P Jewelry with Rin. Rin smirks, taking the opportunity to actually act like a couple while looking at jewelry. Even Rin noticed the energy draining properties of the jewelry on sale even if he did find a few things he would actually like to get for Usagi. Once the rest of the customers were gone Usagi and Rin immediately end the youma, Morga. Usagi uses an Albarn demon hunting art to paralyze said youma while Rin calls upon his weapon to destroy her. Then they go on their way, Usagi typing out their report before sending it off.

Luna just stares in stunned silence at how they had dealt with the situation. By the time her brain has rebooted it was too late to track them down. Usagi nearly yelps when Rin pins her to an alley wall hidden in shadows before kissing her, he was already deciding where his next bite would be placed on his girlfriend's delectable body. Rin knew he was becoming addicted to Usagi's blood yet, no other humanoid blood even appealed to him. He also knew that the suckers that Usagi's grandmother gave him had Usagi's blood in the middle, to tide over his lust for her blood. He could pass off rabbit's blood as cherry juice thankfully. Well, only if no one smelled what was in his cup. That was generally why he placed his rabbit's blood in an opaque sports bottle.

It was only when air became an absolute necessity that Rin ends the kiss, " Usa-chan, where shall I mark you this time, hmm? "

While they are otherwise occupied they have no idea that Lady fate is throwing a bitch fit of epic proportions or that Susanoo ensured they would meet just to screw with Lady Fate.
