Yukio's POV…Reminiscing…

Some people might think that being one of the sons of Vergil Sparda would be a bad thing, especially due to his legacy...I would say that they are dead wrong. I would also say that it is extremely dangerous. People are always out for your head because the line of Sparda is a dangerous one. I suppose that's why I had to disappear.

Demons were hunting us, my family and I were in danger. So, my father, Vergil Sparda, had my mother seal away most of my memories and then used his sword, Yamato, a gift from my Grandfather, the original Sparda, who I would later find out was sealed inside of me and opened a portal to Japan. The two of us disappeared, leaving my father, my older brother Nero, and my Aunt and Uncle, Trish and Dante, behind.

We made a new life for ourselves. We had thought that we had left our past behind us. But, as we would soon find out...we were so very wrong. I enjoyed my childhood while it lasted though. Little did I know, everything that I ever thought to be true would come to an end.

Present Day…

I grunt, cracking my neck, as a very familiar blonde shakes me away. Groaning, I sigh "What's up, Yumi?"

Kayumi Yuuto, my best, and my only friend smiles "Oh, you know, just coming to make sure you make it to school on time, you get it."

I grunt, flipping myself up, putting my school uniform on as we head out "Alright, I guess since you came out here to get me…"

As the shorter girl pushes me out the door, I use the time to quickly put my hair back into a ponytail. What can I say, with hair like mine, you've got to do what you've got to do? It's going to suck with other people though. I'm kind of scared of what's going to happen…

Five Minutes Later…

I sigh, sitting down next to Matsuda, one of the Perverted Trio, with a small salute "What's up?"

He grunts "Not much. Issei, Motohama, and I are going to be going to a peeping spot later if you want to join in."

I blink, shaking my head as Valiana Lucifage, one of the prettiest girls in school, walks in, taking her normal seat behind me "Nah. I'm good. I hope you have better luck with that."

I did my best to ignore the beauty behind me. I sang to myself. I tried focusing on my work. It was hard, but I managed to do it. Barely, but it got done. I managed to survive all of my classes, despite having both Valiana Lucifage and all three of the Perverted Trio in the same class. And that's where my day went from normal to...interesting.

I am normally not considered in any way, shape, or form, by any of the females, to be cute. I have never been asked out on a date, and I don't know the first thing on what to do if I were. As I was putting stuff in my locker, this brunette girl comes up, smiling as a blush covers her face "A-Are you Yukio Kurogane?"

Closing my locker door, I nod, bowing goofily "At your service. What do you need…?"

Giggling, she smiles "I'm Yuuma Amano...I was wondering if you would go out on a date with me."

I blink, ignoring my warning signals. I grin "Alright, I'm game. Choose the place, and I'll be there!"

The brunette grins "How about now? You and I can go out and enjoy ourselves at the carnival, or something."

I shrug "Alright, let's go then!"

All of a sudden, Yumi comes out of nowhere, a small smile on her face "Where are you guys going?"

I gesture "This is Yuuma Amano. She asked me to accompany her to the Carnival, and I said yes."

Eyes wide open, Yumi nods slowly "Very interesting...well, have fun. I'll talk to you later then, Yu."

And with that, we head out. I learned a lot about Yuuma during the date. I even learned a lot about myself during the date, which was the most interesting thing, to be sure. One of the things that I learned thanks to my 'date' was about my lineage...or rather, one thing that she made me remember.

And here I thought that I had been on a good date. As the two of us reached the water fountain, Yuuma took up a weird pose and smiled gently "I had a good time, thank you for that."

I nod, a grin plastered on my face "I had a good time too. We ought to do it again."

That's when the brunette sighs "If only it were that easy. I'm sorry, Grandson of Sparda, but I cannot allow you to live."

All of a sudden, the brunette became a ravenette in a BDSM suit, with black wings coming out of her back. That's when I knew that I was screwed. Lucky for me, Valiana Lucifage, or rather, Lucifer was following me. My day almost went to hell, only to get weird.

As the Fallen Angel threw a spear of light at me, out of nowhere, this white dragon-armored person came out and absorbed it. The white dragon-armored person growled "Get the hell out of here, Grandson of Sparda! We can't let anyone hurt you…"

I facepalmed "What the hell is even going on?! Who the hell is Sparda?!"

Before I could get my answer, I got what I thought to be a light spear to the chest. As it turns out, that would only start me down the path of legends. It would start me down the path of Sparda.

Two Minutes Later…

When I reawoke, the first thing I noticed, besides being in a different place, and the fact that I was a ghost, was that I was surrounded by a red-haired man, and two white-haired women, looking very similar to each other. I grunt "Okay, can someone tell me what the hell is happening to me because I am very confused. First, this Fallen Angel like fucker attacks me, and this dragon lady tries to save me, and now I'm here. And they both called me the Grandson of Sparda. I mean, sure, my Mom never talks about my Dad, or anyone else in my family, like my big bro, but I'm pretty sure that my Mom would tell me if my grandfather had a weird name like Sparda. So, explain yourselves!"

The red-head nods, putting his hands up "Just wait, and give me a second, Grandson of Sparda. First, I will explain how you got here. Before I do that, I will introduce myself and my associates. I am Sirzechs Lucifer, one of the Four Great Satans, the King of the Devil Faction, in the Supernatural World. This is my wife, Georgia Lucifage, and my sister-in-law, Grayfia Lucifage. You are Yukio Kurogane-Sparda, the son of Akami Kurogane and Vergil Sparda, the first-born son of the Great King Sparda, brother to the first-born, Nero Sparda, nephew to the great Dante Sparda. Now, with the introductions out of the way, do you know Kayumi Yuuto?"

I nod, floating there, taking in my family line "Yeah, she's like my best friend...why?"

Sirzechs gestures and a sigil on my shoulder glows red "She planted a sigil, which, after you got attacked by the Fallen Angel, Raynare, allowed me to bring you here because I have an offer to make you. Either way, you live again, but you have two options. Either you are revived as my little sister Rias' Pawn Piece, or you can take on the Title of Sparda. You can become your own master, and gain your Peerage, bringing life back into your Clan, and eventually, becoming the Great King Sparda, like your grandfather before you."

I'm not stupid. I know that if I don't take on the title of my grandfather, something stupid's going to happen, and it's just going to go to shit from there. Besides, I've never really been good at taking orders. So, I do what any smart, self-respecting person would do. I nod "I'll take the job! It sounds interesting...but why me?"

Sirzechs sighs "Obviously your father sealed too many memories. You are not only the most eligible, due to your father, uncle, and older brother all having disappeared, but you are the bearer of the extremely powerful Longinus-type Sacred Gear, Cavaliere Angelo. You will need training...and lots of it. That is why, when you return to your body, I would like you to find Kayumi Yuuto. Tell her about all of this, and ask her to take you to my sister, or Valiana Lucifer. From there, you will come down to the Underworld, and the world will know that the Sparda Clan lives on. I will train you on how to become a Demon and use your Devil abilities, and then you may reincarnate Grayfia-chan as your Queen Piece because you are going to need her expertise. Now go."

With that, I disappeared. I didn't know what was going on, but I also didn't care. All I knew was that Mom had a lot of explaining to do...as did Yumi, for that matter.

Two Minutes Later…

I gasp, sitting straight up and hitting Yumi in the chin "I'm back! Ouch!"

As I rub my head, Yumi pounces on me "You're alive! Wait, how are you alive?! What happened? Vali-sama said that you had gotten attacked?!"

I shrug "I wouldn't necessarily call it 'attacked'. More like 'jumped by a cute girl and got stabbed by a light spear. You know how it goes. Wait, Vali?"

The busty white-haired girl waves from the corner of my vision "Yeah…"

I sigh "Mother has a lot of explaining to do. Yumi, help me up. I need to get home."

The blonde and white-haired girls look at each other and then nod "Alright, but Vali's coming with us."

I shrug "That works for me. Come on then, I live close by."

As we took off for a run, several things went through my head. The girls stayed quiet the entire time, which allowed me to process. I just couldn't believe one thing. Mom has been lying to me since we first came to Japan. She told me that not only was I a single child, but my father left us no choice. She sealed my memories of my family, and she lied to me. That's going to stop though.

Five Minutes Later…

Vali and Yumi watch on as I sit my mother down at the table, right in front of me, and growl, showing my two elongated canines "Okay, you've got a lot of fucking explaining to do, Ma. I have been attacked by a fucking Fallen Angel, and have been told that you've been lying to me, and learned that I'm a part of a legendary family line. Something's not adding up, and you're going to tell me what. I deserve at least that much."

My mother grunts, ignoring the question as she gets up "Do you girls want something? I can easily whip up some ice cream or something since you're here."

I do my best to ignore the rage that her actions have whipped up as Vali and Yumi both nod "Sure, Kurogane-sama."

It was pretty obvious that she was doing her best to have to avoid answering my question, so I did what I had to do. I regretted my actions later, but they were only a means to an end. They got the job done.

I shoot up, slamming my fist into the table and getting the bowls of Ice Cream to jump as I growl "You're going to answer the damn question, and you're going to do it now, woman! I've waited long enough! You've been lying to me about my own family! My very existence has been a lie up until now! Now give me answers! Explain to me why! Say something!"

As Mom calmly walks over to me, her hand glows, and using her first two fingers, she pokes my forehead. All of a sudden, several different memories flow through my head. As my vision starts to return to normal, the last picture that appeared in front of my eyes was one that could only be of my father, brother, uncle, and myself. We were all smiling, and my brother had his arms wrapped around my legs, having the younger me on his shoulders.

As my breathing returns to normal, Mom wraps her arms around me "I apologize for lying to you, Yukio. I didn't want to, but your father and I agreed that it was what was best for you. With that said, your father knew that something would happen. So, he and your Uncle gave me the swords that their father made for them, to, once you became of age, have me give them to you. Now, follow me. You girls may as well come too. If you are going to remain friends with Yukio, you're going to want to know what you're getting into."

I sweatdrop as we walk on, heading deeper into the house "Um, how exactly did I not notice this?"

Mom snickers "You think that I would just put the two legendary swords out on display? Wow. I thought that I thought you were better than this."

I throw up my hands as the girls giggle "Oh, sure. That is exactly what it is. Well, where are the swords?"

She gestures to a black and silver cleaver, hanging from a wall "Well...that's when the weirdest thing happened. As we came here, both of the swords glowed and transformed, becoming one. It became even stronger than before, but only ones with the blood of Sparda can wield them. That means that Amousen is yours, Yukio. Take it, and take ahold of your birthright."

Doing as I was told, I reached up towards the glowing sword and grasped its handle. It just felt right with me. It just felt like family.

As I fixed it on my back, I bow to Mom "Thank you. Thank you for putting up with my shit for all of these years. Thank you for staying with me. Thank you for everything. Now though, I must take my other birthright. I'm going down to the Underworld, and I'm going to train with Sirzechs Lucifer, to become a Devil. I'm going to become like my father, and his father before him. I am going to resurrect the Sparda clan. That much, I promise."

Mom smiles, patting my shoulder "I know you will. If your father could see you now...he would be extremely proud."

That got me to pause "Mom...what did happen to Dad, Nero, and Uncle Dante? That much, I don't remember."

She scratches the back of her head sheepishly "Well...they sealed the portal to the Demon World from the inside. Nero was originally supposed to come with us, to eventually teach you how to use your Demonic Abilities, such as Devil Trigger, but Dante and Vergil were having a hard time closing the portal and required Nero's help. So...they should still be inside the Demon World."

I grunt, walking over to Vali "Well, there is another goal for me to accomplish...freeing my family. Come on Vali, I need to go to the Underworld, and you're the fastest way."

As we disappeared, several thoughts flew through my head. I appreciated Mom's candidness, but it would have been nice to know my family line. I couldn't help but wonder if Sirzechs knew anything else. I guess that I would have to ask him when we get there.

(Author shrugs) "And there you go, the origin chapter to The Legend of The Black Knight. For those of you who haven't noticed, this fic is going to be a slight crossover between Devil May Cry, a little bit of Bleach, High School DxD, and a little bit of My Hero. It will be interesting. On another note, my summer vacation is getting cut short between possibly a summer job, summer college classes, and the fact that COVID is still around, which annoys the shit out of me. But you'll be seeing me still over the summer...probably. Anyway, I would expect a chapter of Blood and Fangs, and probably the Red Leviathan Emperor, along with possibly a new straight-up Bleach fic soon enough. Just giving you a heads-up. Anyway, the next chapter is going to have a small bit of training with Sirzechs, where Yukio unlocks his Sacred Gear, and while he doesn't unlock Balance Breaker, he does show some skill in some of Cavaliere Angelo's abilities. Along with that, we will see Yukio accept Grayfia as his Queen, and trade a Knight Piece with Rias to gain Kayumi, as well as, perhaps, a Rook Piece. So yeah, it should be fun. Alright, peace out, and see you in the next one."
