PREVIOUSLY: Leo nodded to him and escaped the house through the back door, he ran through the dark alleys, slipping right and left through them with high speed, all concerned about Kira's safety.

Leo kept running, running, and running, jumping from building to another without taking a break, trying to get himself any lead to where he can find Kira and Jonathan.

Meanwhile.

Kira slowly opened her eyes then peeked right and left, trying to recognize her surroundings. She could feel something stinging her arms, however.

"Enjoying yourself?"

Kira groaned due to the pain. She looked down and noticed her arms are chained up to the roof with a long chain connected to steel bracelets around her wrists and the other end of the chains is connected to the room and her arms had needles that are connected to tubes, draining her blood slowly.

She was too exhausted, barely able to talk.

"What . . . are you doing . . . to me?" her tone was faint and weak.

"Oh well, you see, I'm trying to build my own army, and to do that I need two ingredients, the salamander serum which I already have. And "O" negative blood. Your blood is needed for further tests to complete the serum. Once it's finally complete I'll have my keys to power in this country . . . Nah'. The whole world, hehe!"

"You can't . . . be serious!"

"Ok fine you got me, I'm not interested in this stupid twisted world. I'm trying to build an army of mutates to conquer the world of "Utopia" and some other realms out there!" Jonathan placed his hand on his forehead while shaking his head.

"Wha-...? What're you..-?"

"Oh, right . . . Well, you see. I'm not really from this world. I used to be a powerful Mage in a world called the "Utopia". But since I've been so naughty they thought they had the right to strip me of my powers. Oh well, they actually did I was so drunk back then. Anywho, to sum it up for you. I'm trying to build up my forces to leave this shit hole!" he seemed irritated.

"You're...- out of your mind."

Cough!

"Not really. Ok, maybe a little but believe me, magic exists, so does God, Jesus, so do demons, angels, and even GODS and dragons. But too bad there are no mages in this world . . . except one!"

"Thought . . . you and my father were old friends."

"Nah'. That was a memory alteration magic, I made him think we used to be friends but nope, never met him."

"W-Why?"

"Like I said, "Your blood!" "

Kira remained silent, she was too dizzy to have a conversation with that psycho.

"I'll tell you since you're a good listener and well, you're gonna die tonight anyway so yeah. Here's my plan, pay close attention..."

Meanwhile:-

Leo kept on searching every street until a thought crossed his mind. He changed course and dashed away with all of his speed until he saw the black SUV cars outside his old house, the one he used to live in with his family before Jonathan murdered his mum and damaged his eye permanently.

Meanwhile Jonathan and Kira

"So, what do you think? BRILLIANT, isn't it?" Jonathan in excitement after explaining his master plan to Kira.

But right then . . .

Screams were heard from the outside of the house!

"AAAAAAAAHHH!"

"HELP-.. *gags*"

Footsteps could be heard coming closer through the dark hallway and a male in a hoodie and a mask, holding two bloody combat knives emerges out of the darkness while twisting both the knives around his two indexes, he was panting, however.

"Well well well, if it's not my beloved s-...." And before he finished his sentence he got shot in the chest once. The shot came from a gun that the serial killer is holding.

"Ouch, that hurts, Leonardo!" Jonathan had a disappointed look on his face, however, the chest wound regenerated quickly and the bullet dropped out.

Kira looked at the bloody murder with a shocked look on her face, "Leo?" the words escaped her lips with a faint tone.

"Wow, you look exhausted, when was the last time you've slept, kid?"

Leo looked at Kira and noticed her condition, the girl was fading slowly, all chained up and having her blood drained slowly.

Jonathan grabbed a scimitar on his table and a bottle of wine, "Hey, want something to dri-.." Yet again he got interrupted but this time Leo was facing him, two centimeters close to his face, trying to stab his chest with the knife in his left hand but Jonathan easily blocked it with the scimitar. Leo tossed a throwing knife towards one of the chains connected to the roof and so the knife stabbed the roof right beside the ring linking it to the roof.

"You sneaky little SHIT!" He kicked Leo's guts with his right toe and surprisingly the kick tossed Leo 10 meters backward, looks like Jonathan is a Mutant as well, not surprising since Nyxx's assistant injected him with the other Serum which was more advanced than the one Leo got injected with.

Both of them were injected with a serum. Leo got injected with the orange salamander serum created by Dr. Marcus. Jonathan was injected with the black Serum made by an elite team of scientists hired by Nyxx herself.

The orange Salamander Serum granted Leo enhanced senses, high agility, stamina, strength, and the ability to regenerate, however, for him to regenerate he has to stay still and focus on the healing process, he can't move, do any action or channel his powers for anything else.

The advanced black serum grants more endurance and strength making Jonathan as resistant as an armored vehicle, its powers are passive, Jonathan can regenerate and heal a lot faster than Leo can, not just that he can move and perform any action while healing, that's why his serum is more advanced than Leo's.

Meanwhile

Nyxx rushed to her basements and looked through some dusty shelves until she found a sealed black box. She made a small cut to her left index and placed it on the box's top. And right away the box unsealed and opened for her. And then, a small ball of blue energy, flickering with electricity slowly levitated out of the box.

Leo coughed a few times while holding his chest, he slowly pushed himself up with a grin.

"LEONARDOOO!!" Jonathan shouted in excitement as he dashed towards Leo, swinging his scimitar towards Leo's neck.

Leo in return rotated on his left toe, dodging. He then threw another knife towards the other chain linked to the other side of the room with his left hand while aiming with his right hand with his silenced gun towards the first knife he threw earlier, shooting one bullet which pierced the grenade attached to the knife, blowing it up, dislocating the first chain off the roof, now one more is left.

Boom!

But then...

Slich!

Jonathan's scimitar went through Leo's back, piercing it as its sharp edge came out of his chest.

"No . . . L . . eo!" Said Kira in a faint tone with a tear.

"Oh wow, that was too easy, ahaha!" Jonathan was so excited after stabbing Leo.

Boom!

The second knife blew up, disconnecting the second chain off the roof, freeing Kira up. Jonathan looked down at Leo and saw him aiming with his other hand with another silenced gun, seems like Leo still shot the second bullet even though he just got stabbed. But that's not it, what really pissed Jonathan up was the grin on Leo's face from the side.

"So that was your plan all along, huh?" Jonathan's eyebrow was twitching.

Jonathan pulled his scimitar out of Leo's back and then, Leo fell on his left side with blood pouring out of his wound, making a blood pool around. Jonathan kicked Leonardo in the guts, throwing him eight meters away.

Smash!

Smith reached the door as fast as he could, "KIRA!" he shot towards Jonathan seven times.

"D-.. Dad?" She had a very faint tone.

Jonathan turned to him and was like, "You serious?" He didn't wait and dashed towards Smith, taking in whatever bullets he can before punching Smith into the guts, slamming him into the wall.

Smash!

"Argh!"

Jonathan picked him up by his left arm and slammed him to the ground before tossing him beside Leo and Kira.

"Now, where was I? Oh yes, Leonardo, my boy!" Jonathan while walking towards the trio.

Kira removed the tubes connected to her arms with a groan, she crawled towards him with tears on her cheeks.

"This view though. . . looks familiar, Hmm...", Jonathan grabbed Kira by her hair, raising her slowly with his strength. After losing so much blood, Kira was too powerless to resist. "Ah" she cried in a low faint tone.

Leonardo remembered how Jonathan slaughtered his mum and then . . .

The scimitar pierced Kira's back as well. Blood poured down her lips, blood was filling the floor.

"NOOOOOOOOOOOOOO!" Smith cried in agony.

Flashbacks of Leo's mother in her last moments after Jonathan's stab to her chest

Orange electricity spark went through Leonardo's brain then to his limbs and finally circled around his heart, his blur vision made everything unclear, except Jonathan, he was as clear as a day to Leonardo. His heart started beating faster, faster, and faster.

And so, Leonardo jumped towards Jonathan and punched him in the face, knocking him off to the wall with a powerful straight punch.

Jonathan dropped his sword, along with Kira. Smith quickly held her while Leo dashed forward towards Jonathan.

"THAT'S THE SPIRIT, COME ON!" Jonathan shouted in excitement.

Leonardo has already lost control, he was like a wild predator now.

Jonathan grabbed a metal bar and tried to hit Leo's face with it.

Tchn!

But to his shock, the predator held it between his teeth, grinning like a psychopath, responding with a powerful punch to Jonathan's face.

All Jonathan could see was the wicked grin on Leo's face and the red glow in his right eye.

Jonathan punched Leo in the face, thrusting him to the wall on the other side. Leonardo rolled on the ground and claws started to grow out of his fingers.

GRRRRRRRRRRR! He growled at Jonathan.

"And that's pretty much it-..." And so he got interrupted by Leonardo's claws striking his chest.

"What the fu-.." Jonathan couldn't believe it. Leo was so fast like a wounded beast.

"GET THE FUCK OFF!" Jonathan punched Leo away from him again.

Leo got thrown away but rolled mid-air and tossed a knife towards the electricity box inside the house, shutting the electricity down.

Slich . . . . . Slich . . . . . Slich . . . Slich Slich Slich Slich Slich Slich Slich Slich!

Jonathan was taking stabs from all directions one after another.

"ARGH, WHEN WILL YOU GET IT? YOU. CAN'T. KILL. ME!"

Flick!

Jonathan got stabbed with over 5 throwing knives with hand grenades attached to them. Leo pulled the ring off one of them before jumping off Jonathan.

"Oh shit" Jonathan exclaimed.

*BOOM - Boom - Boom - Boom - A BIG Explosion!*

"AAAAARGH!!!!" Jonathan was falling slowly to his right side with smoke coming out of his burning flesh.

Smith was holding his daughter in his arms, crying in pain and agony, Kira was just looking at her father, slowly fading away until she felt Leo's hand touching her wounded chest.

"What . . . are . . . . you doing?" Kira with a very faint look and a faint tone.

Leo kept his right hand on Kira's wound still grinning. His arm was bleeding so much his blood started to cover Kira's wound. Kira's wound started to vaporize and produced so much steam. She was slowly healing.

"Live." A faint whisper came through Leo's lips to her right ear as Leo caressed her hair while hugging her with his left arm after using so much of his blood to heal her even though he still has the scimitar's wound over his chest.

And so, Leo pushed himself up, walking towards the back door and going through it. Police Sirens could be heard.

Smith lifted his daughter up and walked to the backdoor as well. The police arrived and all of them aimed towards the male in the hoodie with half shattered mask (Aka Leo). Smith gestured them to lower their guns. And so they did.

Leo walked slowly until he reached the bench in their house's backyard and slowly sat on it, looking up at the moon with a grin on his face.

He searched through his pockets for something with his left hand slowly but couldn't find it.

"Looking for this?" it was Nyxx's voice as she offered him the picture he lost in her mansion while rescuing her from the assassins before taking a seat beside him.

He grinned as he took the picture with his shaky hand. Nyxx moved her own picture closer to Leo's and joined them together, surprisingly the two pictures are actually two halves of one complete picture. The second one joined with the first showing Leonardo, his Mum, Alexandra, their younger sister, and Nyxx when they were a lot younger, grinning to the camera.

Tears were dripping down Nyxx's cheeks and a tear fell down Leo's left cheek from his left eye.

Shadows were covering Leo's eyes but they couldn't cover the tear on his left cheek, they couldn't cover the grin on his face. And couldn't cover the blood flowing slowly down on the ground.

Nyxx wrapped her arms around him, hugging him to her chest while sobbing.

"I finally found you, little brother ... yet . . . . Yet I'm too late."

Leo allowed her to embrace him and raised his right hand slowly, touching her left cheek, sweeping her tear away.

"I love you, big sis!'" And with those last words that came out of his lips, they were followed with his last breath, his right hand fell down, leaving a small line of blood on Nyxx's left cheek, and his mask slowly shattered with the winds as he passed away. The young killer died in his sister's arms with a grin on his face but this time it was so cheerful and innocent, it showed how happy he was to have that one last moment with her.

Nyxx knew he was gone, she cried and mourned her little brother's death.

"Aaaaaaaaah"

Cries!

"Ahaaaaa"

Loud cries!

Kira was put in the ambulance but she survived thanks to Leonardo's blood. She had a temporary link with him and felt the moment of his death when his heart stopped. All she could do was cry in the ambulance and try to sweep off her tears.

And so, the young killer was gone, leaving the love of his life and his sister behind. The police couldn't find Jonathan's body, all they could find was the bodies of the assassins. Smith made sure no one took Leonardo's body, not even his colleagues. They buried the young man in the graveyards.

**Leonardo MacMillan - 2001 - 2017**

That's what his gravestone said.

Kira, Nyxx, Smith, Marcus, and Sarah stood by Kira's mother's and Leonardo's graves, giving their goodbyes to them both.

Kira crouched down and placed a rose on her mother's grave. And another one by Leonardo's.

Nyxx left a bouquet of flowers by Leonardo's grave.

"They will pay for it, little brother. They will all pay, I promise you that." And with that, she left the graveyard, going to God knows where this time.

What's Nyxx gonna do next? How's Kira taking it?
