6 years have passed and Adrien is now 20 years old. He's graduated high school and is now owning the mansion that was once his father's. His mother is so proud of him for growing up to be his own man, even if his vampire side got in the way but it helped change his life. She's now in London with her sister and Adrien can now be the new prince of darkness in Paris. He still had a relationship with Marinette as well. He still is Cat Noir but only out to hunt bad guys like rapists and thugs hurting the innocents. To the public, Gabriel was officially declared deceased. They never found the body but the public was glad that he's gone since he was a maniac for terrorizing Paris.

Right now, an adult Marinette sitting on a park bench waiting for him. The kitty just loves to be sneaky whenever she can't sense him.

"I wonder where he is now," Marinette thought.

She nearly jumped when she saw him hanging upside down from the tree beside her, "Jumpy? As always" He laughed a little.

"Oh, you silly kitty" Marinette laughed that he's sneaky as always.

"Do I get a kiss, my love?" He purred in excitement.

"Of course" Marinette cups his face and kissed him.

Cat Noir kissed his lady back with passion. Purring in happiness when he felt her hands stroking his hair.

"I love you so much, Kitty," Marinette said.

"And I love you too, my puuuurrrrrincess. You're just too beautiful" He licked her cheek.

"Tehehe that tickles!" She giggled.

"It's almost sunset and I have to hunt delicious mice, my love. You know I never let mice get away" He kissed her again.

"Good luck kitty" Marinette scratched his chin.

He purred out loud, loving to get his chin scratched, "See you soon milady" He said before going.

He jumped off from the tree and extended his staff as a pole to get higher to the roof, "The hunt is on again" He ran at full speed on the rooftop. He searched many places for criminals to feed on. His human nature has faded but he still remains a person.

"I don't care! Just get this damn crate loaded! That feline brat is out there somewhere! His claws will tear us apart" A thug ordered his men to load the crate in the van.

"Goddamn it, we are trying our best, boss!" The men said and loads the heavy crate in the back van, "That cat is like worse than bad luck."

"Give me a break. That cat just needs to go eat cat food instead of hunting criminals" One of them said.

"We need some vampire protection stuff," The leader said.

"Like what?" The thug asked.

"Crosses, garlic, holy water," The leader said.

"That should work," One thug said.

Cat Noir growled and jumps down to spook them, "Not for long!" He lands with his fist hitting the ground while crouching.

"Aaahh!!! Goddamn, where the hell did you come from?!" They asked with a startled look.

"From the skies," Cat Noir said with a creepy smile.

"Stop smiling like a Cheshire before I really make it disappear for you!" The leader glared.

"We'll see about that" Cat Noir approached them menacingly.

"What the hell are you doing?!" They all back away.

"It's time to kick ass and drink blood" Cat Noir said.

"OPEN FIRE!" The leader ordered them to fire at him, which they did.

But again, the bullets had little effect on him and he pounced on the leader, biting him. Then he goes for the thug too.

"NO! STOP!!! YAAAAAARGH!!!" The thug screamed as Cat Noir bites him. Draining him as quickly as he can before the leader gets up. The thug's body fell lifeless to the ground as Cat Noir let go of him.

He then felt a knife stab through his back, "Got you, you vampire freak!" The leader said.

"Did you?" Cat Noir pulls the knife out and tossed it aside while the wound heals rapidly.

"What monster are you?!" The leader asked.

"I'm Paris's night guardian," Cat Noir said, grabbing him and draining him as well through his bite.

The remaining thugs ran away in fear. Cat Noir finished feeding and went after the thugs before they try to spread the word, "Not so fast!" He attacked them one by one, throwing hard punches, elbow strikes, and kicks at them.

He then hypnotized them to make sure that the memory of his discovery is erased and that they don't remember it, "Sleep and you won't remember last night" Cat Noir commanded.

They all passed out as Cat Noir got rid of the bodies, "The deed is done" He wipes the blood off.

-

Soon he went back to his mansion and saw his lovely lady waiting for him.

"Hello kitty" Marinette greets him.

"Meow, you just can't get enough of my attractive eyes like rubies" He teasingly said.

"Red is a lucky color," Marinette said.

"For love" Cat Noir held her by the waist.

"You purr like a cat" She stroked his hair.

"Because I am one," Cat Noir said.

"But also a batty kitty," Marinette said.

"I'm always batty for you, milady." He nibbled her neck.

"Yeaaaaaaah" Marinette moaned.

"Meow, that was adorable" He purred.

"Thanks, Adrien" Marinette said.

"Am I still your favorite kitty?" He rests his forehead against hers.

"Yes. I'm glad we've been a couple for years" Marinette said.

"And you're living the life of being a fashion designer," Cat Noir said.

"Yeah" Marinette held his hand.

Suddenly, the fireplace flamed up and it was his father. Luckily, he can't step into the living world because of the rules of being dead. Marinette hated that man for what he's done years ago.

"Gabriel!" Adrien glared, refusing to address him as his father.

"How dare you show your face here! You can't walk in the living world" Marinette said.

"Too bad, but I will be haunting you all for imprisoning me here," Gabriel said.

"You can't touch us; you've paid for your sins. Satan has punished you for all eternity. You can't escape Hell because your soul is claimed by him" Cat Noir hissed.

"Thanks to Dracula himself!" Gabriel yelled, his eyes burning.

"Dracula is like a father to me. A father that loves me, remembers my birthday, respects my interests, and my freedom" Cat Noir said.

"And now you got this baker girl as your girlfriend!" Gabriel glared.

"Yes, Chloe was never the one for me!" Cat Noir folds his arms.

"Nor was Lila. Love comes from the heart. Chloe and Lila have no heart the same way you have no heart for anyone!" Marinette glared.

"Another thing. You may have let nasty people into your mansion but you never let nice people into your heart. Just like you never let me in when I was a kid. Goodbye, Gabriel" Cat Noir takes out the fire extinguisher and aims it.

"AHHHHHHH!!!" Gabriel screamed as he was extinguished.

"Go back to where you belong, Gabriel. Now, where were we, my lovely bride?" Cat Noir brings her to the bed.

"Oh yes. My lovely kitty" Marinette giggled.

"You're so puuuuurrrrrretty when you're human" He purred.

"So are you as a vampire," Marinette said.

After all these years, Ladybug and Cat Noir continue saving Paris from all threats, even without Shadow Moth threatening the city. With the cat now the secondary guardian they have become a more effective team. Thanks to becoming a vampire, Ladybug has learned to never reject him again and accepted his love and usefulness in heroics.
