Later at midnight, Adrien had another nightmare of using cataclysm on innocent people. He saw his cousin asleep on another bed with Kagami by his side since he's very protective of her. He walks to the window and stares at the Eiffel Tower, thinking of what to do to end his father's madness before the kwamis are completely drained from being forced to do his bidding.

"There is only one way to finish this once and for all," He said to himself.

As he remembers correctly, his father had the spellbook that contains all the past holders from Ancient China. There was no way that it was a gift from Emilie.

"I must retrieve the book and find a solution," He thought.

"What are you doing up?" Plagg asked with a tired yawn.

"I'm cooking up a plan to save the kwamis," Adrien said.

"Kid, you're not strong enough. If he finds out you're the cat, he'll know who you are" Plagg said.

"I know" Adrien sighs that his cat kwami is right, "If I can't be Cat Noir, maybe there's a miraculous I can find at the Louvre. Plagg claws out" He transformed into Cat Noir and jumps out the window to head to the Louvre.

Once he arrived, he crawls inside the air ducts. He was looking for the exhibit of Transylvania since the last time when the incident of Pharaoh happened again, he remembers the miraculous symbol of the bat.

He jumps down from the vent and went to find it, "If I'm correct this miraculous has a very special power, better, not life drain" He thought.

He soon came to one glass case with a medallion inside, resembling Count Dracula's from the 1930s.

"Meow. Such a lovely artifact" Cat Noir said, using his claw finger to unlock the lock from the glass display.

He picks the artifact and examined it, "Must be one of the rare European miraculous"

A red flash came out of the medallion and there stood a black bat kwami, "Greetings. I'm Fangs" The kwami said in a Transylvanian accent.

"Aww....how adorable. I'm Cat Noir but I'll tell you my real name later. We gotta get out of here, now" Cat Noir said.

"Gladly" Fangs agreed.

Cat Noir jumped up to the air ducts and crawled out of there, "Another purrecious item to the collection" He said to himself.

"Your accent is not like my holders. You seem different" Fangs followed him.

"I'm French" Cat Noir explained.

"Ah, the sweet language of love" Fangs said and they came to the vent that leads outside.

"Let's go before Ladybug finds out" Cat Noir whispered.

They got away from Louvre and back towards his hideout. He detransformed and told Fangs his real name. Plagg was a bit jealous but his kitten can't risk going as Cat Noir.

"Ah, I'm grateful for getting a new holder after centuries" Fangs said.

"Temporary actually. But I'm afraid someone is gonna need it but that will come later. I need your help because I ran away from my father and he's become insane for power and miraculous. I can't fight him but I need to steal something from him. Can you help?" Adrien asked the bat kwami.

"Gladly. I'm at your service" Fangs said.

"Merci. So what's the word?" Adrien asked.

"Just say Fangs wings flap," Fangs said.

"Alright. Sorry Plagg, but I need to use the bat miraculous" Adrien said and reaches for his ring.

"You promise you'll evolve back to a cat?" Plagg asked with a serious tone.

"Of course, I will" Adrien replied and takes the ring off and puts it in his pocket, and puts the medallion on, "Fangs, wings flap!" He transformed into a bat-themed hero, a leather suit appeared on him with wings folding out under his arms, his eyes turning pure red with a black mask and bat ears. Pointy fangs appear on his upper lip and he does his stance.

"Time to retrieve what's ours" He flew to the mansion.

Going from roof to roof. His night vision made him see better and his bat ears made him hear everything. Once he was at the mansion, he opened up the window to his former room. He noticed the monocle on his desk.

"Okay, let's see what Felix recorded" He puts it over his eye to view it.

Nothing happened but when he adjusts it, he sees scanners of fingerprints on his door.

"There it is" He saw how it went.

If there are fingerprints, then there's a clue to his father's office. He opens the door and slowly went downstairs to his father's office. Whatever his cousin found in there, it must be more than just a secret. He goes to his mother's portrait and smashed the safe lock to get the book.

"Perfect. All mine" He picks up the book but then the alarm went off and he growled angrily, "Shit!" He smashes the window and ran off with the book in his hands.

He didn't get the chance to find out what else his father is hiding from him. He will have to come back next time when he's ready. At least he got what he needed. He flew back to the hideout quietly without waking Kagami and Felix up.

"Fangs, wings closed" He detransformed back and puts his ring back on while heading to bed.

The book in his hands was definitely ancient. Hewill have to look at it tomorrow morning, "Night Plagg and Fangs"Adrien said before he went to bed.

The next morning, Felix is the first one to wake up while Adrien is asleep. They didn't know he went out last night and it got him very tired. Kagami is still holding a grudge against Felix for what he did at the Diamond Dance incident. Felix however blamed himself for giving the miraculous to the one person he hated the most, feeling like a hypocrite after seeing the condition the kwamis were in. He thought he could plan to get Ladybug and Cat Noir's miraculous to make his wish come true but in reality, it only made things worse for his cousin and himself. There was no going back but he can change his mistake.

He knew he was past forgiveness. He looks at Kagami sleeping peacefully like she's never gotten that much sleep.

"My queen" He smiled.

Adrien wakes up from his sleep and goes to the table to pour a glass of milk, "Slept well you two?" He asked.

Kagami stretched her arms waking up, "Enough beauty sleep, yeah"

"And you, Adrienette? Did you sleep cutely?" Adrien asked his kitten.

"Meow" Adrienette nodded.

"Where did you get the kitten?" Felix asked.

"I found her in the alley all alone without a mama" Adrien explained.

"Ah, so she's an orphan?" Felix guessed.

"Yup. And I'm gonna visit my princess to introduce her to the kitten. Plagg claws out!" Adrien transformed into Cat Noir, "You ready to see your new mama?" He tickles his kitten.

"Meow" Adrienette meowed as he carried her.

"How long have you been Cat Noir?" Felix rolled his eyes.

"Since being 13, same time as Ladybug" Cat Noir replied.

Marinette was waiting for her kitty to arrive since she's got breakfast meal for him to eat so he doesn't starve to death.

"I'm happy that my kitty is taking care of my prince, Tikki. He deserves to have the freedom he got" Marinette said.

"Yes, no more rules or being forced," Tikki said.

"But I still don't understand why his father is so strict. Mostly every parent approves their kids" Marinette said.

"I wonder that too. If he dislikes people who aren't rich" Tikki guessed.

"Rich or poor, everyone is human, Tikki. There are no differences" Marinette said.

They heard a thud on the roof and Tikki went to hide. Marinette ran up and opened the trapdoor.

"Hello princess," Cat Noir said.

"Hey, kitty. Aww....you got a kitten?" Marinette lets him inside.

"Yeah, for you and Adrien," Cat Noir said.

"What's her name?" Marinette asked.

"Adrienette, after you and your purrecious purrince," Cat Noir said.

"Oh, kitty" Marinette hands her kitty a plate of breakfast and hold Adrienette in her hands, "Thank you so much" She petted her kitten.

"You're welcome, Princess" Cat Noir and ate his meal rapidly since he's very hungry in the morning.

"Oh, Kitty. You must be starving" Marinette said.

"This poor kitty has been so lonely on the streets, princess. It's hard to find food" Cat Noir said playfully with sad eyes.

"I see. So is Adrien still alright?" Marinette asked.

"He is. He's getting used to the freedom he has" He said while taking a few bites of his meal, "He was the one who told me to bring you the kitten this morning"

"How sweet of him" Marinette smiled.

"And I believe you are finally becoming Mrs. Agreste-Cheng, my princess" Cat Noir teased her and finished his meal.

"Just a few more years until we'll have a nice wedding," Marinette said.

"I can imagine a lot of flowers and music," Cat Noir said.

"Just like you tried to do with your lady" Marinette giggled.

"It was way back then" Cat Noir replied.

"Meow" Adrienette meowed at Cat Noir.

"Hey, Adrienette" Cat Noir pets her, "Daddy is gonna come see you, kitten. Mommy is here for you now" Cat Noir purred.

"I didn't know you care for animals," Marinette said.

"I do Princess, mostly cats," Cat Noir said.

"You did rescue a cat once," Marinette said, remembering when he saved a cat from a tree.

"Yeah, and licked my cheek. Anyways, I must go now, princess. Your prince will be here soon and I got some mice to hunt. I'm a very wild cat" Cat Noir hands his kitten to her.

"Okay good luck Kitty" Marinette waved.
