I've been looking forward to writing this for a while ^o^ Just FYI for those of you that know of it - this is not part of the Strawhat series, though you may notice similarities in certain books.

Anyway, this story will be fairly short, like less than ten chapters. Pre-timeskip, 9 members. Have fun reading~

Zoro strolled through the woods, the bright full moon lighting his path. They would be departing the island the very next day, and he was feeling restless, so he had decided to take a short walk outside.

Finally starting to feel tired, he turned and began heading back to the ship. Thankfully, the ocean was in sight so there was no chance of him getting lost (not that he would have gotten lost, of course).

But as he reached the edge of the forest, he heard a low growling behind him. He turned to see a yellow-eyed brown wolf in an aggressive stance, staring at him.

"What?" he muttered. "You wanna fight or something?"

The wolf sprang. Zoro jumped aside and drew his swords, but the beast skittered around and clamped its jaws around his leg.

"OW! Stupid—!" Zoro slashed at the wolf's muzzle, leaving a long mark across. The wolf whimpered, turned tail, and ran, apparently deciding that Zoro was too tough of an opponent.

"Dumb wolf," Zoro muttered, looking down at his bleeding leg. He started making his way back to the ship, but before he took even three steps, he felt a sudden dizziness overtake him and stumbled.

"Wha . . ." he mumbled, his eyes rolling up in his head. His knees buckled and he hit the ground.

Zoro slowly opened his eyes and pushed himself up. He felt bile rise in his throat and vomited into the grass. He remembered that he'd fainted earlier and realized that it had only been for perhaps half a minute.

"I must be more tired than I thought," he muttered to himself. He stood shakily and finally went back to the ship.

As he boarded, Chopper approached him (the little reindeer was on lookout duty) and said, "Zoro, what were you doing outside?"

"Going on a walk," Zoro said nonchalantly.

Chopper gasped, spotting Zoro's leg. "You're bleeding!"

"Yeah, a wolf bit me," Zoro admitted. "It's not a big deal."

Chopper frowned. "Come to the infirmary. I'll wrap it up."

Zoro reluctantly followed him to the office and sat down, pulling up his pants leg.

"It doesn't look too bad," Chopper said, wiping up the area with rubbing alcohol and starting to wrap bandages around it. "Let me know if it gets worse."

"Sure," Zoro said. He stood when the doctor had finished and left. "I'm going back to bed."

The next day, Zoro felt awful. He barely got himself out of bed to stumble to the kitchen for breakfast.

"Wow, you look like crap," Nami commented as he sat down.

"Way to greet a guy," he muttered in response.

Sanji served up breakfast as Chopper said, "Zoro, are you feeling okay?"

"Just tired," he mumbled.

"Oh," Chopper said. "Well . . . get some sleep today."

"You'd better," Usopp added. "It's your turn to be lookout."

"When're we setting sail?" Luffy asked around a mouthful of food.

Nami rolled her eyes. "After breakfast."

"Oh," Robin said in surprise, reading the paper. "This says that there's supposed to be another full moon tonight."

"Really?" Franky asked. "Don't they usually happen just once a month?"

Robin nodded. "Every few years, a full moon happens twice in as many days. It's called a blue moon."

Brook chuckled. "It sounds rather romantic!"

"Nami-swan, Robin-chwan, how about we all have a romantic dinner tonight?" Sanji cried with hearts in his eyes. "This is a perfect and rare opportunity!"

"Yeah!" Luffy exclaimed. "I want a romantic dinner too!"

Sanji glared at him. "Do you even know what romantic means!?"

Luffy shrugged.

"You're hopeless," Sanji said with a sigh.

Zoro managed to finish his breakfast and pushed back his chair. "I'm going back to bed," he muttered.

He spent nearly the whole day sleeping. Chopper wasn't too concerned, since Zoro had been up the night before and it was his turn for lookout duty that night.

Despite this, he was feeling even worse as the night fell, though he hid this from his crew. As they went to bed, he climbed up to the crow's nest and let himself fall onto the bench.

He really was feeling sick. His head was pounding, his stomach ached, and he felt hot and rather prickly all over his body. To try and combat this last symptom, he stripped off all his clothes except for his boxers, leaving him practically naked in the small room.

The moon was beginning to peek over the horizon. All of a sudden Zoro's entire frame began to tremble violently as waves of pain wracked his body.

"Ah—!" he hissed, breathing shakily. Black spots appeared in his vision.

The last thing he saw before falling unconscious was thick green fur sprouting on his limbs.

As the dawn broke, Zoro slowly opened his eyes to find himself lying on the floor of the crow's nest. He struggled for a moment, but managed to push himself up into a sitting position.

The first thing he noticed was that he was completely naked, though since no one else was around he wasn't too concerned about this.

The second thing he noticed was that everything looked strange. Yes, all the stuff in the crow's nest was where it usually was, and nothing was out of place outside, but the colors were different. The sky on the horizon, normally an orange-ish color at this time of day, was oddly yellowed. The part of the sky that was deep blue seemed fairly normal, at least. The ceiling of the crow's nest had changed from red to yellow as well, and the benches were also that sickly yellow color. Zoro looked at his arms and found that they too had become a strange yellow color.

"What the hell . . . ?" he mumbled. And then he felt something underneath him and looked down.

The third thing he noticed was the large and fluffy tail between his legs.

He almost yelled out in shock. Stopping himself, he stood shakily and twisted his head around. The tail appeared to be light purple-gray and firmly attached to his backside—when he tried to make it move, it twitched in response.

Oh.

A sudden headache overcame him as memories from the previous night flooded his mind. He sat down hard.

Turning into a wolf. Colors becoming strange. Powerful jaw. Muzzle. Growling. The need to attack. Hours pacing around. Dawn breaking. Whining. Hair shrinking back. Falling.

Turning into a wolf.

Oh.

His first thought was, I'm a goddamn werewolf.

His second, and more chilling thought, was, Thank god no one came out on deck last night.

It explained the previous day and night, though. Thinking about it, he supposed that the wolf which had bitten him had actually been a werewolf, and of course he became one the next night, since—that's right, Robin had said it would be another full moon.

It also explained why he was seeing the world in strange colors. He had heard that dogs were colorblind, but he had always assumed that being colorblind meant seeing the world in black and white, not these sickly shades of yellow and blue.

And of course, it explained the tail attached to his backside.

I can't tell the others. They'll only worry.

He was sure he could find some kind of solution—after all, he had assumed werewolves to be mythological creatures until now. If there wasn't some kind of reversal process, wouldn't there be werewolves running amok everywhere?

But he would have to worry about this later, for at the moment he was completely exhausted. Yawning, he pulled his boxers and pants on, tucking the tail into them so as to hide it from his crewmates. It was a bit uncomfortable, but nothing he couldn't handle.

After he finished getting dressed, he slowly came down from the crow's nest and went straight for the men's bedroom. He spotted himself in the mirror and noted that his hair was the same color as his tail had appeared to be—a kind of purple-gray. He supposed that this meant his tail was, in reality, green like his hair. Flopping down onto his bed, he promptly closed his eyes. When Luffy tried to wake him for breakfast, he shook off his captain, saying that he'd eat something later and he just wanted some goddamn rest.
