Daichi's POV…Two Days Later…And here we have a Training Montage before Rias finds him, the two of them have to go up to Heaven to get Rebellion, she mates with him, and they go down to the Underworld and the events for the Young Devil Tournament start to unfold! And I pity Daichi, I do. But hey, let's have fun at Daichi's expense!

I growl, my headphones blasting hard rock as the Chaos Edge appears "Alright, let's get this party started then."

I charged at the rocks that I had set up, and the Chaos Edge glows. I grin "Dragon Shot! Calamity! Dragon Buster!"

{Dragon Shot!} {Calamity!} {Dragon Buster!}

The three-shot combo destroyed the rocks, obliterating them from the face of the earth. I couldn't help but laugh. Back before I started to train, I would have to plan out my shots and all of that. Now, I don't know what to do with myself!

I stretch out, grinning "Alright Acno, let's do a little bit of work. Balance Breaker!"

{Balance Breaker: Chaos Dragon Scale Mail!}

My armor forms around me, and I quickly shift into a fighting stance as Acnologia rumbles, able to hear Tiamat snoring in the background "{Why not just meditate and see how long you can maintain Balance Breaker for?}"

I grunt, mentally preparing myself "Because I need to be able to switch forms faster in Chaos Calamity Drive. Now then, Go, Chaos Blazing Paladin!"

{Blaze Boost!}

As my armor changed to the familiar set of the Chaos Blazing Paladin, I swung my sword around, cutting through the air. Back and forth I come and go. Eventually, I take to the sky, using Yamato's ability to make myself go faster. It's always best to keep practicing, even if you know how things work as if they were on the back of your hand.

Eventually, I eject myself from Balance Breaker and sigh "Well, that was fun."

As my playlist switched from AC/DC to Metallica, I turned it down on my headphones "Acnologia, is there anything else I should do for training?"

My dragon partner grunts "{I can't think of anything. If you could figure out how to unlock what your sister sealed, I'd say something else, but until then…}"

I sigh, shaking my head "Great...I've done everything that I can do without anything new to train for then. Fuck."

I hear a slight whistle and spin around to see the busty red-head that reincarnated me in the first place, Rias Gremory. I smile "How's it going, Ri? You're up early!"

The shorter girl rubs her eyes sleepily "I couldn't sleep because of the loud explosions thanks to you...how do the other ones do it?"

I shrug, sweatdropping "Sorry...and you know, I don't know? Shirone can sleep through a freaking train though, I know that much."

She laughs, rolling her eyes "Are you done with training already? Irina-san did tell me that Lord Michael has unlocked Rebellion for you…"

Instantly, I race forward, stopping as our faces are mere inches from each other, stars in my eyes "Are you serious?! Can we get it? Please?"

The red-headed heir to the Gremory clan sighs, nodding "I never should have opened my mouth, in hindsight. Let's go...don't expect me to be so nice later."

I grin, feeling just like a kid in a candy shop. I was complaining about not having enough to do for training, and now I've got a new sword to train with! It's amazing! Rias summons a magic circle and we teleport away, heading off to Heaven and my new sword!

Five Minutes Later…

I keep my hand attached to the red-head's as we walk along, heading to Heaven's armory. I can't help but smile though. Normal people wouldn't want the burden of being the bearer of one of the most powerful Longinus', definitely the most powerful Dragon-type. I'm perfectly happy with it. It fits in perfectly with the rest of my crazy life, so why the hell not?

Michael meets us in front of the armory and grunts "I see that you have brought a visitor this time, Daichi."

I nod "Yeah, she's the one that told me that you had been able to unseal another sword, so I figured that she should come along. So, which is it? Rebellion? Sparda?"

He smiles softly, shaking his head "Just like a kid in a candy shop...Rebellion has unsealed itself and is ready to meet its new wielder."

He gestures, and so I lead the way. As the three of us walk in, the Chaos Edge reappears and Tiamat grunts "{Done with training already, kit?]"

I smirk "Well, Tia, Rebellion unlocked. So no, I'm not done…"

I let out a low whistle as I draw the blade "Damn! This is sick!"

As I swing it back to my back, it forms it's own scabbard even! I jumped for joy, it was so cool. Rias snickers as I do a little happy dance, overjoyed that I got something to train with "You're a goof, you know that?"

I shrug, blushing slightly as I realize what I just did "Eh...yeah, Keiko-nee tells me that a lot, not going to lie. Now then...you want to go back home?"

Almost instantly, Rias shakes her head "No, I want to be out and about with you. Everyone else has gotten their turn, but not me!"

I smirk "You're telling me that you, Rias Gremory, the heir to the Gremory clan, are jealous of the other girls?"

She pouts as we walk out, leaving Michael behind "I'm not jealous, it's just not that fair to me!"

I snort "Yeah, that's the description of jealous, Ri. Don't worry though, unless we've got something to do, this can be our day. Hell, if you don't want to, we don't have to even go home!"

What I was thinking at the time, I have no idea. I wasn't about to take it back though. You never know what might happen!

So, the two of us teleported away, where we were going, I have no idea. I didn't care though. She was right, I was not giving everyone enough time to be with me. I had been with a few of the other girls, but not Rias. Sometime soon, I would also have to talk to Akeno too...I'll has to make it up to her, that's for sure.

When we reappeared, Rias was in a crop top and short-shorts, carrying a single tent case and a large pillow, and a couple of other items as well. I blink "How the hell?"

She smiles "I know a bit more about magic than you think I do, Dai. I know how to make you stop in a portal while I keep going. Don't worry, I was quick about it. Now come on, we can set up camp and spend the day here in this beautiful place, or we can teleport to Kyoto and have a shopping spree, or I'm sure there are a million other things to do. So, what's the plan?"

I completely dismiss Rebellion, it joins Yamato in the pocket dimension that I made. I grunt, shrugging "I don't care, it's up to you. I'm just here for the ride, you know?"

Rias rolls her eyes, kissing my cheek as she yawns "Alright then. Why don't we set up camp and then just snuggle?"

I raise an eyebrow "Just snuggle? You don't have any other plan for that?"

She giggles softly, winking seductively "I guess we'll have to set up this tent so that way you can find out, won't we, Daichi?"

Now, I know that technically makes me think with my dick, but I didn't care. I had been planning on making Rias one of my mates for a long while now, and this was the chance, we finally had a free moment! I had quickly set up the large red tent in record time. Rias let out a low whistle and I have to admit, even I was impressed with myself. Normally, when I set things up quickly like that, it completely fails.

I start breathing hard, my hands on my knees "I need to figure out how the hell to breathe when I run like that, holy fuck!"

The red-head pats my back, pulling me inside "You'll be okay, Daichi-kun, I promise."

As I flop down onto the sleeping bag, I can hear the sound of zips and in the back of my head, I knew that Rias was taking her clothes off. Part of me wanted to spin around, simply so that way I could watch her and know what was going on, but I decided not to. I didn't want to be extremely creepy, you know?

I can feel my lower back being massaged and I grunt, starting to transform into a humanoid dragon, purring "You're good at that...holy fuck...are you a fucking goddess in disguise?"

(An M-Rated Scene Is About To Occur!)

Rias smirks, kissing the top of my head "No, I am a mere mortal, sorry to disappoint you Daichi."

I purred, spinning around and burning through my training robes, scales forming over my face and my fangs elongating slightly as I continue to transform "You don't disappoint me, Rias...but I am worried that I will disappoint you. You're not only a high-class devil, but you're also the heir to the Gremory clan and my master! Sure, I'm one of the three legendary Dragon Emperors, but I'm a low-class devil, a pawn. I don't deserve you. I don't deserve this. I don't know what I'm thinking anymore…"

Rias growls, slapping my lights out. Her eyes narrow as I rub my scaled cheek "You don't think that you deserve me? You saved me from that prick, Riser Phenex. I would rather be a low-class Devil if I could stay with you than be a high-class devil and not do anything, or be with you at all. My virginity belongs to you, Daichi Fukada, just remember that."

I grumble as she kissed my cheek, right where she hit me, transforming me back to normal "Gee, thanks...love you too, Ri."

All of a sudden, Rias kisses my nose and starts to make her way lower. Yup, my little friend was at the ready. What would you expect me to do? I'm a straight, heterosexual dragon male and she's a very sexy female! Can you blame me?

Rias pushes my friend right between the two of her breasts, rubbing them up and down. I groan, completely covered in two pillows of utter awesomeness. Within minutes, I completely blew up, right in her face. Rias, staring directly at me, swirls her tongue around, collecting all of the white stuff before swallowing it. Just like that, I was ready again.

As a dragon should, I spun Rias around, her 'flower opening as her legs spread. I put any doubt of taking Rias' virginity from my mind, as she wanted me to do this, and I pushed myself into her opening. She grunted, first in pain, then in pleasure. As I started to slowly pick up the speed of my thrusts, she started to scream my name. I was very pleased with the outcome. And soon enough, the same pressure that I had come to recognize as 'fun-time' was upon me.

I grunted, struggling to hold back the waves of pleasure "Are you sure you want this to happen, Rias? This is your last chance to back down because I'm about to blow again!"

The red-head nods, her eyes starting to roll "Please, make me your mate! Show me the power of a Dragon Emperor!"

I growl, nipping her shoulder as I pick her up, continuing to thrust "As you wish, Rias-sama...hope you're ready because here I go!"

The flood was released. I filled her to the brim. As I pulled out, I lay down beside the red-haired girl, pulling her body close to mine as I kiss her forehead, transforming back "That was fun, no?"

The only answer that I got was a quick, chaste kiss before the Gremory heir was sent into the depths of slumber. Soon enough, I joined her. What would you have expected me to do, stay up throughout? Nah, I think not.

(The M-Rated Scene Has Ended, You Youngsters May Return!)

The Next Day…

I grunt as the two of us teleport back to the house "You sure that we can't stay here another day? We could go another round if you want."

Rias smirks, holding my hand as we walk along the path "As fun as that sounds, no, we can't. We are going to need to pack because we are all going on a little road-trip down to the Underworld! My brother would like to see us."

Almost instantly, any sort of joy that I felt at being home, however small that joy was, was erased. I was to go down to the Underworld, to the realm of the Devils. I have no idea, but I am fucking terrified. Oh wait, maybe it's because I'm dating, and have now mated with Maou Lucifer's sister and we're going to go see him! I might be the bearer of the most dangerous Longinus, but this is the strongest Maou we're talking about!

I grumble as I jog up to my room, opening the door to reveal twin balls of fur curled up near my pillow. I blink "Acnologia, when did we get cats?"

My dragon partner snickers "{Those aren't cats.}

Tiamat grunts, the ever-supportive "{You're an idiot, you know that?}"

I blink and then remember. Those are my cats! And for once, Tiamat was right, I am an idiot."

I smile evilly, jumping and flopping onto the bed. Up the girls went, down the girls went. The next thing I know, Kuroka has her hand inches from my face, claws extended as Shirone growls "Leave us behind again and I swear that I will fucking kill you and bring you back again, Daichi Fukada."

Kuroka nods "I won't stop Shirone-nee either. You had us so scared! The only reason that we didn't just make a search party and look for you was that Akeno-chan said that you were with Rias."

I sweatdrop, and then grab both of the girls, bringing them close "Well, thank you for not just killing me now. I'm sorry that I didn't tell you. Rias did make a point to me though, she and Akeno are my girlfriends, and you guys and Asia are my mates. I spend more time with you guys then I do them, so I had to change that, besides, Lord Michael unlocked Rebellion for me. We had to get it anyway, and it was early, so we made a date out of it...and things happen. Anyway, we need to get ready, because we're going to the Underworld to see Maou Lucifer and the rest of the Gremory clan."

Kuroka yawns, pulling her obi on "Fine...come on, Shirone-nee."

I grunt, grabbing the short white-haired girl before she can leave "Nah, the Queen's with me. We'll be coming down in a couple of minutes."

The black-haired Nekoshou rolls her eyes as she leaves, closing the door behind her "Don't you mean an hour later? Come on, Dai, I'm not dumb."

As the door closes, our lips meet. As much as I hungered to be with Shirone, I knew that I shouldn't. It would take much too long. So, I did the next best thing. I snuggled with her.

As I nuzzled her neck, she purred "I missed you, Daichi...you had me worried that something bad had happened to you."

I grin "Something bad, to me? You mean besides you?"

Shirone growls, playfully smacking my chest "Stop being so mean!"

I kiss the top of her forehead as I sit back up, determined to get ready, no matter what might happen when we get there "Alright, alright. Besides, you already know the truth, you're one of the freaking best things to happen to me. Now come on, we should probably get ready. And yes, you can pack your stuff with mine, my Queen."

Ten Minutes Later…

As all of us finished packing, Irina hit me over the head "You're an idiot, you know that? Everyone was super worried about you."

I shrug "I can take care of myself, so...now come on, Ri, we should go!"

The red-head rolls her eyes, a rueful grin plastered on her face "Alright, alright, since you're so eager."

As we teleport away, I notice that both of my hands have been taken, one by Asia and one by Rias herself. I didn't care. I also resisted the temptation to see whether or not Asia was wearing any panties. I just pretend to not care as we get onto a train and head out to the Underworld. The entire time though, I'm fucking panicking.

Can you blame me? I don't know how well Maou Sirzechs Lucifer, the strongest Maou and Rias' Older Brother, would take to me! I mean, I did destroy Rias' engagement to Burnt Chicken Boy after all. I also became her mate, surprisingly. Call it a bad thought, but I immediately knew that I was so screwed.

Once we finally stopped, Rias still basically attached to my hip, she drags us along "Come on, let's go!"

I sigh "I'm going to die."

As we walk into the Gremory Mansion, Rias looks around "Mother? Millicas!"

A shorter, crimson-haired boy runs over and Rias lets go of my hand to pick him up, swinging him around "Hello, Millicas-kun! How were you today?"

He smiles, about to say something, and then he makes eye-contact with me. I smile, waving "Hey there."

Instantly, Millicas' jaw drops and he squirms out of Rias' arms and shoots over to me "Y-you're the Chaos Dragon Emperor…Auntie Rias, this is the Chaos Dragon Emperor..."

I grin, summoning the Chaos Edge "Yup, that's me, Daichi Fukada."

As Millicas practically scours the Chaos Edge, this elegant, busty brown-haired woman walks out. I grunt "Wow, Ri, never told me you had an older sister."

The red-head snorts "That's not my sister, Daichi, that's my mother."

I sweatdrop, bowing rapidly as everyone starts to laugh "I am so sorry!"

The brown-haired woman smiles "It is perfectly fine, Fukada-san. My name is Venelana Gremory, and I am Rias' mother. It is nice to finally meet you, Rias tells me a lot about you. I see that you are good with kids, and you've already made a friend out of my Grandson, so that is going for you."

I blink as Millicas continues to look over the Chaos Edge, and then he points at the white jewel "I know about the green and the blue and violet jewels, but what is the white one? What power is that?"

Tiamat answers for me "{That is my jewel, child. Daichi absorbed my soul into the Chaos Edge to reunite me with my mate.}"

I grin as the shorter boy looks at me in wonder "Well, it is a long story, but yeah, I guess."

Rias' mother bows "Well, thank you for gracing us with your presence. Now, come along as we show you to your rooms."

Well, that went much better than expected, not going to lie. Then again, they haven't realized that I mated with Rias. Yup, I'm going to die. I'm not going to regret making Rias one of my mates, but I'm going to die nonetheless. I've realized this, and I've accepted this. Though, Rias' mom's looking at me like she's expecting something. I've got no clue. Here's hoping that I make it through life though!

(Author sighs) "Oh my God, thank you guys for the support on this Fic. It's truly amazing how many people enjoy this. I've also come up with a system so that way I don't delete stories that people enjoy. If more people like the stories than those that hate them, they stay. If it's the other way around, they go. Yup, I'ma big brain, I know. Anyway, onto the storyline. As you can see, we're moving along quite well. Daichi meets Sirzechs next chapter and realizes that since he beat Riser, he took his place as Rias' fiance, though he would eventually like to do it himself. He then has to go through a bunch of edicate and training like that, and then he and Rias have to go through a test...and fight the Satan Rangers. That will be fun. After that, they meet Azazel, who introduces them to Tannin, who offers to spar with Daichi. Daichi jumps at the chance, and the two are pretty evenly matched, as Daichi is using Rebellion the entire time. After that, it's the Young Devils meeting, and rating games, and Sairaorg vs Daichi, and Sairaorg uses Breakdown the Beast and would have destroyed Daichi if he hadn't unlocked the Queen form of his scale mail at the last second...yeah, that's enough spoilers though. I don't want to give too much away, you know? Alright, I hope you all have a good day, review and like and all that if you want, and peace out!"
