Luffy turned away from his opponent and gasped when he saw the cat sitting in the doorway. "Oh no! She followed me!" He shouted waving his arms in the air.

"She followed you?" Nami shrieked angrily. "You led her here?"

"Oops?" Luffy said, half as a question. He wasn't sure if he was supposed to apologize or not.

Nami rushed the black-haired boy but Zoro caught the back of his robe. "No time for that," the swordsman said, giving Nami a brief shake. "We've gotta get out of here!"

"Right!" Luffy said with a grin. "Run away!"

Like a flash the children scattered. Nami grabbed Zoro's hand, the redhead knew it would be better for the swordsman to spend the rest of the night in the Gryffindor common room then for him to try and make it back to the dungeons himself, plus Nami wasn't about to let Zoro wander off with Malfoy.

Luffy grabbed Hermione, despite her objections, giggling as he drug the girl behind him. The Slytherins followed, as no one was eager to be caught out of bed at this hour by Filch.

"Let go of me!" Hermione hissed trying to get her hand back but also take care not to trip. Luffy just turned to her a grinned widely, but didn't respond and didn't let go.

"This way!" Nami said directing the group away from the trophy room. They could hear Filch's hurried footsteps behind them and his grizzly voice calling out for them to stop.

"We don't have to outrun Filch," Nami said under his breath, still dragging Zoro behind him. "We just have to be faster than Malfoy and his goons."

The group ran for what felt like hours. Nami led them up a flight of stairs and stopped, panting when he saw an entrance to a hallway he wasn't familiar with. "Here! Duck in here!" He called, ushering his crew in.

Zoro moved further in followed by Luffy and the ruffled Hermione. Nami made a face when he saw Malfoy had kept up and followed them in.

"What are you doing here, Malfoy?" Nami asked still leading his crew down the hall.

The blond sniffed and turned away. "I wouldn't have followed you, but Potter grabbed me when I lost Crabbe and Goyle," Malfoy said shooting a glare at the grinning captain who nodded along. "I wouldn't be following you otherwise! I don't need you!"

Nami rolled his eyes and gave Luffy a look that basically said 'really? Why help him?'

Luffy just grinned, the adventure and thrill of the chase exciting him like nothing else had since he started finding his crewmates.

"Where are we?" Hermione asked as she tried to smooth down her hair. She hadn't been able to pay much attention to her surroundings with Luffy dragging her along.

"The third floor," Nami said, nerves leaking into his voice just a little. "I know Dumbledore said it was forbidden but we had nowhere else to go. Filch is fast."

As soon as he heard forbidden Luffy's eyes lit up and Nami had to grab his collar to keep him from running off. "Oh no, you don't!" Nami said tugging him closer. "We need to get back to the common room before we get caught."

"But Naaaami!" Luffy whined. "Mystery floor!"

Zoro glared at Malfoy when the blond scoffed at Luffy's whining.

"We should-," Hermione stopped when she heard a faint meowing and the children all exchanged looks.

"Not again!" Nami cried looking for a way out but didn't see one. The only way was the entryway they had come through and long hallway.

"There a door!" Zoro said pointing at the door he found. The dark-skinned swordsman rushed to it and tugged at the handle uselessly. "It's locked!"

"I don't have the time to pick it!" Nami cried frantically.

"Oh, move over!" Hermione said shoving the Slytherin away and pointed her wand at the handle. "Alohomora!"

The lock clicked and Zoro eagerly pulled the door open and pushed everyone, even Malfoy inside.

The five children pulled the door closed and pressed their ears to the door to listen. It appeared they had hidden just in time because the meowing came closer and they could hear Filch muttering and calling for any out of bed students to come out and face their punishment.

The kids waited until the noises got further and further away and breathed a collective sigh of relief.

Nami was the first to face the room properly and when he turned he made a noise that sounded like a high pitched squeak.

"Eh? Nami?" Luffy asked turning to see what was wrong with his navigator.

"Dog!" Luffy cried happily.

Zoro, Malfoy, and Hermione all turned when a low, deep, and loud growling sound echoed through the room.

"That's one big dog," Zoro remarked calmly. The swordsman grunted when Nami made a whining noise and jabbed an elbow into his side.

"I think he wants to play," Luffy said happily as the giant Cerberus licked its chops, all three sets, and growled louder.

"I think he wants to eat us," Nami whimpered. Hermione nodded in agreement.

"Zoro, wanna play with us?" Luffy asked cracking his knuckles. If the dog wanted to fight then Luffy would gladly give the beast a fight.

"I've gotten better at my no sword-style," the swordsman remarked stepping forward with his captain. "Let's play."

Draco wanted to scream, he was having a terrible night. First, Potter had almost been late to the duel. He had considered not even showing up but mentioning to Professor Snape that he had heard Potter and his crew talking about pulling a prank in the trophy room to get them all in trouble.

That thought hadn't lasted long, he wanted to beat Potter more than he wanted to get the other boy in trouble. So he gathered Crabbe and Goyle and went to meet him.

Second, they hadn't even gotten the chance to duel! The stupid caretaker and his mangy cat had made sure of that and then they had to run away. Running wasn't the problem. Draco had always been rather fit and even losing Crabbe and Goyle wasn't much of a problem. They knew better than to tattle on him and they were too stupid not to get caught so he knew his only choice was to follow Potter.

Now, staring down a three-headed dog with teeth as long as his forearm, Draco was regretting not taking his chances with Filch.

Hermione slapped her hands over her mouth to keep from screaming. The muggle-born girl watched as Harry and Blaise marched forward to the dog. She didn't know what they planned on doing but it couldn't be good or safe.

Beside her, Ron was the only one having a normal reaction to stumbling upon a Cerberus. Harry, who was several inches shorter than both Ron and Blaise, looked all the tinier standing face to face, er faces, with the Cerberus.

"Hi, doggies!" Harry called standing with his hands on his hips. The three heads growled loudly and the head on the left snapped dangerously closer to the small black-haired boy.

"He's going to get killed!" Hermione cried.

"Luffy and Zoro can handle it," Ron said. The red-headed boy appeared to have gotten himself under control. Ron looked different in that moment and Hermione couldn't figure out why.

"They're going to die!" Draco said, reminding Hermione that the blond was still with them.

"Just watch," Ron said watching his friends face down the beast.

The Cerberus appeared to have grown tired of waiting. The beast lunged forward, all three heads snarling and snapping at the two boys.

"Bad dog!" Zoro shouted but he was ready. "Tatsu Maki!"

The Cerberus yelped and stumbled back when the spinning attack hit the left head.

"Damn it," Zoro swore, and shook his arms. "I'm so weak. It barely moved him!"

Zoro's pint-sized captain giggled and shook his head. "My turn, my turn!" He said bouncing in place. "Gum-gum...oh...," he paused and looked from his place on the ground up to the gaping maw of the Cerberus' right head which was growling even as the left and center head recovered from Zoro's attack. He wasn't able to stretch like he had with his devil fruit, instead, Luffy would have to get up close and personal.

"Problems, Captain?" Zoro asked as he taunted the other boy.

"Ne, mean Zoro! I can do it!" Luffy said puffing out his cheeks. "It's just different!"

"Well, you better do it now!" Zoro said jerking his head to the dog. The great three-headed beast was ready for more.

"Gum-Gum," Luffy said dropping down into a crouch. The Cerberus snapped its heads forward and Luffy jumped up and slammed his fist into the center head's nose. "Pistol!"

The force pushed the dog back making Malfoy and Hermione gasp. Not even Zoro's strange attack had done as much.

"Hehe," Luffy chuckled. "You want another?" The boy asked seeing the Cerberus was still ready to fight. "Fine! Gum-Gum...!" Luffy jumped back into the air and raised his leg as high as he could. "Ax!" He brought his leg down right in the middle, hitting the snarling center head hard enough the dog fell to the ground with three yelps.

Luffy fell to the ground with a thud, his jump and subsequent kick throwing off his balance and throwing him to the floor. The first-year grinned wildly and pushed himself up. He was covered in dog fur, dust, and his fist was already bruising but he looked more like 'Strawhat' Monkey D. Luffy than he ever had since his re-birth. Beside him, even swordless and irritated that Luffy had finished the fight his swordsman too, bore a more striking resemblance to the 'Pirate Hunter' he was in his past life.

"Geeze, Luffy," Nami said from the door. "You knocked it out! I didn't know you were that strong, already!"

"Hehe," the former rubber boy grinned. "I didn't know I was either!"

"We are still pretty weak," Zoro reminded them. "All of us, we need to start training again."

Luffy nodded wildly in agreement.

Nami rolled his eyes. "Of course that's your first thought after beating a Cerberus, Zoro," Nami said.

Hermione's mouth was open and she knew that Malfoy was just as shocked even if the Slytherin boy wouldn't show it. What had started with a childish 'duel' between rivals had ended with a chase and a short battle between two first years and a large, three-headed dog.

Hermione had thought that Harry and Blaise were going to end up injured or worse the moment they stepped forward to...honestly Hermione hadn't understood just what they sought to do when they stepped forward. In no way did fighting the great beast make any kind of sense.

The fact they didn't even bother to use magic wasn't half as troubling as their willingness to fight the dog in the first place.

"We need to get out of her before, Fido, over there wakes up and wants to play some more," Nami said giving the unconscious Cerberus an uncertain look. "It might be safer if we spend the night on the Sunny, instead of trying to get back our common rooms."

"All of us?" Zoro asked, meaning Malfoy. "Do we really want to bring him too?"

Nami shrugged and looked helplessly at Luffy. "Well?" he asked, as he looked at his captain for a decision.

Luffy paused and looked at Hermione. The boy's bright green eyes appeared to stare into her soul. She gave a sigh of relief when the boy turned his gaze to the grumpy blond and did the same for a long moment.

"You can't tell anyone about this," Luffy demanded. "You've gotta promise!"

Surprisingly the Slytherin boy just nodded passively, seemingly lost in thought and Hermione followed suit. She just wanted to be away from the dog and somewhere she could sleep.

"What is this place?" Hermione asked as she looked around the room in shock. She turned around to look at the door and gaped when the door sank into the wood of the wall, becoming almost invisible.

"Why is the room moving?" Draco asked flailing as the artificial waves rocked the Merry-Go.

"It's a ship," Nami said waving one hand casually and covering his mouth with the other. "Hermione, I'll show you where you can sleep. Malfoy, go with Zoro and Luffy."

"Go with them where?" Malfoy questioned suspiciously.

"To the bunk room," Zoro said dryly. "To sleep."

"Come on!" Luffy said with a sleepy grin. The former-rubber boy grabbed the blond's wrist and tugged him forward.

Nami smiled, a bit sharply, as and watched gleefully as his captain drug the reluctant Slytherin off to the bunk room. "I'll show you the girl's room," Nami said. "I usually sleep there but I don't want to make you uncomfortable so I'll crash with the guys tonight."

"Thank you," Hermione said softly. The redhead could see that the night's activities had obviously weighed heavily on the girl.

"Hey," Nami said opening the door to the girl's quarters. "Are you alright?"

Hermione bit her lip and nodded. "It was just... a lot tonight," She said clenching her hands.

Nami sighed. "Yeah, but Luffy and Zoro had everything under control. You were never in any danger," Nami said soothingly.

"No, no, it's not that," Hermione said shaking her head. "The Cerberus was frightening, but... the floor, did you see the floor?"

"What do you mean?" Nami asked furrowing his brow. "What about the floor?"

"There was a trap-door, the dog, it was standing over a trap-door," Hermione said.

"Malfoy's gone," Zoro said crossing his arms. Despite the late night adventure, the crew was up early, even if Luffy had to be roused with the threat of missing breakfast.

"Hermione, too," Nami said. "I let them both out this morning. I reminded them that they both promised not to tell anyone, and neither of them knows how the room works. So we don't have to worry about finding them here again."

"Hermy won't tell anyone," Luffy said. The pint-sized captain's voice held a certainty that Nami didn't feel.

"And what about Malfoy?" Zoro asked.

Luffy frowned. "I don't think he'll tell anyone either," Luffy said. He looked like he was thinking hard and his voice wasn't as certain as he had been with Hermione.

"I guess we will find out," Zoro said.

Luffy shrugged and shoved a finger up his nose. "Maa, I'm hungry," Luffy whined. "Let's get breakfast."

SBS: Nami's Wand

Unlike Ron, Nami isn't using a hand-me-down wand. This is because of his saving and stealing habit, Nami managed to save enough money to pay for his own wand when he turned eleven.

Nami's wand is vine and dragon heartstring 13 and a quarter inches not very flexible.

Vine wands are strongly attracted by personalities with hidden depths and Nami is a great example of that. In the beginning, we see Nami as simply a money hungry thief but over the course of the show, we see Nami was a fiercely loyal and protective woman who is fighting tooth and nail to free her island. This hidden depth comes to a great shock to the crew but eventually leads to her true goal of creating a map of all the world's oceans. Dragon heartstring wands are powerful and can be rather flamboyant.

Nami's particular wand has a knack for weather spells and when young Nami went in to purchase his wand the moment he stepped foot into the wand shop a clap of thunder rolled out making Nami's the third time Mr. Olivander had witnessed the phenomenon of a vine wand emitting a magical effect upon the mere entrance into their room of a suitable owner.
