Chapter 7: The Dark Knight's Bloodline

I'll probably make something clear first: More Devil Arms from Devil May Cry will appear. So far, I decided to add the Sword of Sparda (a key element in the plot), Alastor and Artemis (the gun, not the goddess) later in this fic. If anyone has any other ideas for which other Devil Arms Percy/Nero will use, leave those in the reviews.

Oh, and I'm thinking about a betrayal story where Percy, Jason, and Piper are descendants of AC protagonists (Jacob, The Kenways, and Aveline, respectively.). Give me an idea on who their assassin ancestors should be. (AND NO SHAY CORMAC, PLEASE.)

Nero POV

Two months later...

It's been quite a while after I joined the legion, and apparently, my life has changed indeed.

Jason and I were like full fledged brothers-in-arms now. We were both children of the eldest Olympians, and were natural leaders. He also told me about not being able to see Thalia again after joining Lupa. Man, if he finds out about her.

Reyna completely forgave me for the whole "C.C. Spa incident". She was like a sister I could ever ask for.

Piper and I pretty much started dating. She wasn't like the blonde bimbo that betrayed me just because I was different. I trusted her so much.

The Fifth Cohort was restored to its former glory since we won more War Games and Mural Crowns. This earned me the respect of pretty much everyone in New Rome.

More of the Olympians realized I was in Camp Jupiter, eventually. Jupiter and Juno didn't seem to mind, saying something about "a friend of Jason is a friend of ours.". Apollo started acting like he just won a lottery on who gets to turn Kronos/Saturn into their personal slave for a lifetime.

I remained the most laid back centurion in the Legion. (sigh). I guess old habits really die hard.

"Hey, Hotshot?" I heard someone call me. It was Piper.

"Uh..yes, Beauty Queen?" I asked.

"We're in the middle of a meeting." she told me.

"-and...Centurion Redgrave, you look lost in thought." Jason stopped right in the middle of his speech to speak to me. Soon, pretty much everyone turned to me with confused looks on their faces.

"Yes, sir but, I'll be fine." I replied, struggling to get out of my thoughts.

Someone flashed in the middle of the Senate House. It was my adopted mother, Lady Vesta, wearing her orange Roman stola as her eyes blazed like the hearth.

"Son, can I speak to you in private?" she asked, shocking me.

"By all means, Mother but, what's going on?" I asked.

"There's something...urgent that Minerva wants to talk about with you about."

I was confused, so, I stood up from my seat to follow my adopted mother outside the Senate House. Seconds later, we disappeared in a column of flames.

We reappeared in an abandoned car plant in Detroit, where Athena and Ares were waiting.

"Hey there, kid." the war god said.

"Judging by the Greek forms, this is not going to be pretty." I grunted.

"Yes, our champion. My bimbo of a daughter has been acting odd lately, for a cheating b****." Athena hissed.

"Is it so suspicious people should be concerned?"

"Most likely, kid." Ares replied.

"Is Olympus on alert?" I asked my mother.

"No, son. Most of them dismissed it as paranoia. Your ex-father was like 'Screw that s***'." the goddess of the hearth replied sadly. Ugh. I hate Poseidon.

"Well, I say we remain cautious." Athena suggested. "Nero, you remain in Camp Jupiter while we find out what's going on."

"As you wish, Milady."

With that, I was flashed back to the entrance of the Senate House, concerned at what she said.

It's been a week and I still haven't gotten over what Lady Minerva had said. The legion isn't ready to know of my past yet so I kept what I learned to myself. I'm walking to the Field of Mars for fresh air as I relieve my thoughts.

"What are you thinking now?" someone snapped me out of my thoughts. Again, it was Piper.

"Nothing, Pipes." I lied. And, just my luck, she eyed me again.

"You really think I'll let you, my boyfriend, hide secrets from me? Tell me, Nero. What are you thinking now?"

Well, now I'm screwed. The thought of it all: Jason, Reyna, Octavian, Frank, Leo, Hazel, Gwen, even my own girlfriend, knowing the truth about me: a former graecus, an outsider. No. I can't let them know. If they do, they'll leave me, Octavian will probably try to kill me, etc.

"Well?" Piper asked again, crossing her arms and glaring even deeper into me as I shuddered a little. Then, I just looked back at her.

"The thought of everyone here knowing who I really am is too much to handle." I replied.

"You can just tell me straight away, Hotshot."

"I'm not going to let you get involved in my personal problems." I retorted.

Before she could speak, we heard rumbling from the Field of Mars. I also saw a shadow enveloping it. It was shaped like a man with horns and wings. When I looked up, I saw something gigantic descend on the Field of Mars. It was a colossus the size of a building, with black and gray wings, golden curved horns, and an angry look on its face. I turned, and I saw Piper fainting and landing on the ground with a hard thud.

"Piper!" I screamed, attending to her side. I saw Frank with his bow. "Frank!" I called. "Get Piper somewhere safe!"

He nodded and carried Piper somewhere deeper into New Rome. I looked back at the colossus as it landed on the Field of Mars. Jason and Reyna ran to my side.

"What is that thing?!" the son of Jupiter demanded.

"I have no idea, Jason. If it intends to destroy us, then we have to stop it now!" I replied.

I decided to scout ahead so I ran to the colossus to find out what was going on about it until I was directly in front of it. I saw someone on top of the colossus's head, and holy f***ing s*** do the Fates hate me.

"Hello, Jackson. Fancy yourself a Roman?" the blonde bimbo sneered.

"Chase. What the hell is this colossus?" I demanded.

"This is for Camp Half-Blood's protection. As their guardian, I have permission to take out any threat to Camp." I saw Richie stand beside her.

"Protection? This place is also touched by the gods and if you destroy New Rome, you turn against the gods!"

"It doesn't matter what gets in our way. The Savior will destroy all our enemies! For it has a special power source." my ex-half brother said.

"And from what we saw, you have a new whore." Annab**** scoffed. How dare they?!

"You touch Piper and you die!" I yelled, pointing Blue Rose at her.

"Why would Rome keep you, Seaweed Brain? You're just a freak who deserves nothing but pain! Savior, destroy him!"

The colossus raised its gigantic right arm, wanting to smack me with it. I stored away Blue Rose and launched Devil Bringer's power at it but it got broken as it swung and I got smacked a few meters away. The "Savior" charged up again, this time, with a ball of energy. I lost it when I remembered what they said. I charged the colossus with Red Queen, only for the giant to blast me with a barrage of glowing energy. Only this time, it knocked me into New Rome.

Piper POV

When I woke up, I ran only to find Nero being smacked all the way here by the giant. I watched in horror as he skidded on the ground and slammed into the nearest building.

"NERO!" I screamed. I saw Reyna glare at what looked like a blonde girl on top of the giant who was laughing hysterically. I rushed to my boyfriend's side and I saw how battered and beaten he was. His face was bloody, his coat and hoodie were torn (his weapons were unharmed), and I saw how much pain there was in his eyes before he passed out. They were full of anger and betrayal. How could I not have noticed that?

"What happened?"

I turned around and saw Lord Apollo running to Nero.

"Lord Apollo, help him!" I pleaded.

"I'll do what I can!" he replied, making me feel relief. Moments later, all the gods flashed in. What shocked me was Neptune about to impale my boyfriend with a trident but Lord Jupiter, Lady Minerva, and Lord Mars stopped him.

"What is HE doing here?!" the sea god demanded.

"I, along with Vesta and Mars brought him here because you didn't care about him anymore!" Minerva retorted.

"Who cares?! I never wanted a freak for a son anyway!"

I gasped. Nero was a son of Neptune? Cast out just because he was different? How could he be so cruel?

"You do not say that about the demigod who risked his life for all of us!" Lord Jupiter yelled at Neptune.

"Why you-"

Finally. The sea god stopped talking when ALL the other gods aimed their weapons at him.

"Don't even think about it." Lord Pluto hissed.

"Try anything and I'll shove this fireball up your throat, ears, or ass." Lady Vesta growled. I've never seen a peaceful goddess get this angry before.

"And now look at what's happened! Your other son, a real disgrace, no offense, Jason for making a pun on your last name," Mercury said. "has betrayed us by attacking New Rome with a gargantuan monstrosity of a statue!"

With one last grumble, Neptune flashed away. I saw Lord Apollo carry Nero to the infirmary.

"N...N...Nero...was a...son of...Neptune?" I stuttered.

"Yes, my daughter." my mother said. "He was a son of Neptune."

"Father, is there a way to destroy that giant?" Jason asked Lord Jupiter.

"I tried to flash into it but it's not working." the sky god replied.

"We can only destroy it from the outside. Fire!" Minerva ordered as all the gods launch blasts of energy at the colossus. When the smoke cleared, there were no dents.

"Well, we're screwed." Lord Pluto muttered.

"It hasn't even moved yet for some reason." Lord Mars wondered.

"We must plan this out fast!" Lady Minerva stated.

What have I gotten myself into? Is this what Nero meant by his "personal problems"?

In Nero's mind, Third Person POV

Nero woke up in the middle of a giant cathedral at the sound of a demonic yet noble voice.

"Anger and revenge is not the motivation you should use in combat." it said.

The young demigod looked up to see an insect-like demon with curved ram horns, clawed hands, beetle wings, gray and gold scales, and a gem on its forehead.

"Who are you?" Nero asked.

"I am your many greats grandfather, Sparda, Champion of Erebus and Tartarus." the demon replied.

"I get a demon for an ancestor?"

"It's a long story. Ever since the Olympians' rise to power, I begged for my patrons to suppress my demonic power, so that I may not be considered an enemy of Olympus. Regardless, my demon blood was inherited for many generations until today, where you got my blood, Perseus. That day, Erebus had released the surppressor in the demonic side of your blood."

For once, he didn't yell back, for he feared his ancestor's unrestrained power.

"That bimbo of a wisdom spawn has used my favorite sword to power that...monstrosity of a statue. But first things first, is there anything, other than anger, that drives you to fight?"

Nero thought about an answer to the demon's question.

"To protect my friends, sir." he muttered.

"Then use that as a motivation to fight back and not your anger, for it is not always the best motivation."

"Sparda...is there any way to defeat the Savior?"

The demon thought about it for what felt like days then he beamed with success.

"This may be a risky mission but, you must locate enough Devil Arms."

"Devil Arms?"

"Unique and long forgotten weapons forged by Tartarus. Your katana, Yamato, was of my possession and is a Devil Arm. It would seem that the Savior can only be harmed by a Devil Arm, since it is powered by another, which is my sword but, there is one...thing that the traitors forgot."

"What is it?"

"As of right now, my sword is currently in a dormant, longsword-style state. They did nor fulfill the conditions to unlock its full strength, even if they can still harness its energies. And those conditions are: true love, and a noble cause. You can fulfill all those conditions, Percy but for now, you have to find the nearest Devil Arms and use their combined power to weaken the Savior. As of right now, Yamato and your Devil Bringer aren't enough."

"Y...Yes, Sparda."

"In time, you will be like me. To win this fight, you must embrace the demon within."

Meanwhile, in the Senate House...

"Reyna, you're hiding something, aren't you? You look like you know the blonde girl on top of the statue that knocked Nero out." Jason said coldly as his fellow praetor gave him an equally cold look.

"I know that she is a lying and traitorous scumbag who abandoned Nero for power!" she yelled.

"What are you talking about?"

"Everyone, I think it's time you knew the truth." Minerva announced.

"About what?" Leo asked.

"The truth about Nero, who he really is and why Vesta had to adopt him."

How will they react?
