The sound of swords clashing. The cries of war as people fought each other for one side to win once and for all. Your forehead scrunched in pain as you released a groan under your breath. You felt like half your body was covered in several layers of ice, cold sipping through your veins, and numbing your muscles. It was difficult to open your eyes as you attempted to move the side of your body the virus had yet to take over.

"A-Ah! Don't move, (y/n)! The antidote is not done yet!" Chopper cried out, his voice bouncing from somewhere behind you.

"Chopper?...What happened...?" you grunted, turning your face in the direction of where you thought he was.

If only you were aware of everything that happened while you were out of it, from the moment you transformed to where you collapsed after the wheel ran out of time and your stamina wore off.

"Marco helped us to contain the virus for some time, but it won't be long before those affected by it lose themselves again!" the doctor replied.

You shot a look in his direction, seeing that he was currently working at a makeshift desk with several test tubes. He was transferring substances from tube to another, brows furrowed in concentration as Tristan prepared the ingredients on the sideline with Miyagi watching over Chopper carefully. One tube in particular turned a pink color for a brief moment when the doctor dropped a liquid from the pipette:

"Alright! All we need to do now is make a lot of them!" he stated with a firm nod. "A little more time and we will be able to save everyone-"

A scream interrupted Chopper mid-sentence, everyone looking in the direction it came from. It seems that Boss Hyogoro got hit by the virus as his skin turned a shade of blue, his underlings panicking at the sight. He cursed under his breath, warning the others to not approach him under any circumstance.

"I can't die here...Not yet! I haven't paid back my debt to Luffytaro-san and the others! If I'm gonna die anyway, I'll at least stop the enemies for them!" Hyogoro said, his body suddenly growing bigger in sizes as he sliced down a few opponents coming his way.

"(Y/n)! I'm sorry to ask that in this state, but I will need a cannon!" the reindeer shouted at you.

"Cannon?..."

Miyagi was quick on his feet, bringing forward something that used to be a cannon mounted on a carriage. One could say it would still be useful to aim...if the bore wasn't completely destroyed that is.

"I've heard of your skills as a master gunner, (y/n)-sama" the Mink bowed his head. "Unfortunately, these are all the parts we have around us"

"I could probably change the parts broken with some scraps of metal, but I hope you aren't expecting to shove some heavy artillery in there" you hissed in pain while you managed to stand up. "This cannon can only shoot from a short distance by its current state"

"It will be enough! We just need it in shape to fire!" Chopper said.

You didn't waste a second on working to reshape the cannon before Chopper was done with the antidote, ignoring at your best the lingering pain in your body. It took more time than usual since your good hand was damaged and frozen by the virus.

"HELP ME, ROBIN-CHAN!!!!!" the familiar cry of a lovesick cook suddenly shook the halls of the floor you were on.

You nearly dropped your tools from the sound and out of surprise by this random call of help that came out of nowhere. Your gaze drifted to a strange mouse on top of a beam at the ceiling, one that you didn't notice until now. Its face was covered by a sheet of paper with a single eye on it. If it wasn't of Sanji's embarrassing pleads for help, you wouldn't have discovered it.

"I'm on the third floor! The Banquet Hall I've been taken hostage! I'm sorry!" Sanji continued through the speakers. "If Robin-chan doesn't come, they'll kill me! HEEEEEELP!"

"...His pathetic voice is echoing all over the island..." you deadpanned. "The enemy is most likely- no, definitely - a woman. How useless can he be against them?"

The fight kept going on as you heard multiple explosions while you put the finishing touch on the cannon. Marco was struggling to keep at bay the All-Stars by fighting both King and Queen at the same time, while the samurais were running out of time for their comrades affected by the virus. Some turned back into mindless Ice Onis, attacking anyone on sight.

When Chopper finished the antidote, he was barely standing on his two legs anymore. He laid against the slab of a broken wall, panting heavily as the virus began to spread further on his body.

"Chopper! Everything is ready!" you ran up to him, kneeling down to his height.

"Thank you...All there is left to do is clear the final problem. It's this cure's reliability" the doctor showed you the tube in question. "Which means we will need a guinea pig. Since it was thrown together, we can't administer it to patients until we make sure it's safe. So...I'll try it myself!"

"What?! You can't be the guinea pig!" you said. "What if it isn't the case?! We can't risk losing our doctor!"

"I don't have a choice, (y/n)! You need to monitor me closely. We don't know what external changes may occur as side effects-!"

You didn't let him finish his sentence that you snatched the test tube away from his hooves. Chopper let out shouts of protest as you pulled your head back and drank the antidote. You cringed at the awful taste at first, before you began to have some difficulty in breathing properly. You grabbed your throat, squeezing your eyes in pain under the observation of Chopper, Miyagi and Tristan. The next thing you know, a fever hit you while smoke came out of your skin that cracked the ice into pieces.

The others gasped in surprise when your breathing returned to its regular pace and the ice began to disappear. You watched in amazement the smoke clearing the virus away in a short amount of time, deeming the antidote as successful.

"It worked!! Let's get on with it! Everyone is waiting!" Chopper grinned happily.

You ran to drag the cannon outside while Chopper went ahead to put a stop at the samurais fighting each other. Boss Hygoro, whose stamina has reached its end, sat cross-legged while he waited for Yatappe to bring down his sword to end his life before he could hurt his allies. None of his underlings wanted this old man to face such a fate, Yatappe's hold wavering on his weapon. It was pure luck or a miracle that Chopper was able to intercept the two before Boss Hyogoro's life came to an abrupt end:

"Don't stop me, Raccoon-san! We have no choice!" cried Yatappe with tears in his eyes.

"I need you to wait! I'll save him now!" Chopper replied, shooting the cure in the pipette inside Hyogoro's mouth. "Boss! Swallow it!"

The samurais watched in anticipation, gazing in shock at the smoke coming out of Hyogoro's body. The boss tumbled backward while his body began to warm up and the ice broke in pieces. Yatappe quickly hovered his boss in concern, only to cry in relief when he saw that he was completely cured. The samurais cheered loudly at this small victory:

"Raccoon-san, give the cure to Boss Ohmasa, too!" Tsunagoro pleaded.

"The cure is on its way!" Chopper replied, watching as you brought out the cannon with the help of Miyagi and Tristan.

"Everything is set, Chopper!" you told him. "Alright, everyone. I want you all to open your mouth and say 'Ahh'!"

You kicked the lid shut right after the Minks put inside the pink capsule filled with the antidote, aiming the cannon right in the direction of the samurais and the Pleasures who began to panic at the sight of the weapon. With an evil smirk that would scare the Devil himself back to Davy Jones' chest, you fired the capsule that exploded in a huge pink cloud that covered most of the floor.

"Inhale as much of the mist as you can!" Tristan instructed.

"This is the most effective way to save you from Ice Oni!" Miyagi added.

The moment the antidote filled their lungs, all who were affected by the virus turned back to normal to their relief. They cheered at Chopper's success, who at the compliments, began to blush furiously while trying to discard their comments with insults (in which he failed horribly). This victory was short-lived, unfortunately:

"What do you think you're doing, Raccoon?!" a voice roared in anger. Queen stepped on the stage in his dinosaur form, looking as angry as ever. "What have you done to my masterpiece?!"

"It's impossible to give the medicine individually to thousands of warriors on this floor! So I crafted my own virus out of the antibody!" Chopper retorted to his disbelief. "A bad virus can be beaten by a good virus! This way, everyone can ingest the cure by inhaling the mist!"

"You're just a doctor from a petty pirate group's ship...Where did you learn such skills?!" Queen growled.

"We scattered all over the world and trained ourselves!"

"Even my dumb subordinates recovered from Ice Oni! How dare you?!" The comment made Chopper grit his teeth in anger.

"You shouldn't use a virus in a fight so casually! It'll surely get out of hand!"

Queen clicked his tongue and spat his huge cigar on the floor just in front of Chopper who had to leap back to avoid being crushed by it. The All-Star raised an invisible brow at the doctor's audacity:

"Why do I have to be taught ethics by a raccoon? Who do you think I am?!"

Queen fired a barrage of bullets at Chopper who stood his ground. His eyes widened when some Pleasures decided to shield him from the bullets with their own body. They only laughed at the pain, the two opponents glaring at them in shock:

"What are you guys doing?! Get out of my way, you weaklings!" Queen ordered with a spat.

"Shut up, Queen! Our brothers were almost killed by you, and were saved by Raccoon-san here! Instead of death due to a crazy superior, we'd rather die siding with the one who saved us!" a Pleasure answered. "Isn't that right, guys?!"

"Raccoon!!" roared the other Pleasures in unison, lifting their swords skyward, and the samurais did the same in toe.

"You shitheads!" Queen roared in displeasure, groaning when Marco appeared and grabbed him in a circle of flames by his throat.

"That was impressive, Raccoon! Do it!" Marco grinned.

"Thanks, Marco! There's one more thing that I wanna say! Rumble!" Chopper spoke while taking a bite of a Rumble ball. "Monster Point!"

Chopper jumped high in the air while Marco released Queen at the same time. The beast shoved his arm backward before delivering a hard slap on Queen's face that would certainly leave a mark and make him see stars for a bit. All the while yelling to the horrified faces of everyone:

"I'M NOT A DAMN RACCOON!"

"We are so sorry!"

Right-Brain Tower, inside the Dome...

Momonosuke's group were on the run again after their last hideout was discovered by the enemy. The child was currently hiding inside Yamato's top while the others were paving the way. Kotaro was running ahead, the tanuki acting as a lookout for them.

"There is a big space between each floor of the castle! No one will see us there!" Yamato told them.

"Momonosuke-sama! Just a little more patience!" Shinobu stated with a smile.

The moment was short-lived when more enemies appeared at the end of the hallway. Both fighters quickly handled the waves of opponents easily, sending them crashing through walls. However, the kunoichi didn't see one coming from behind as Yamato warned her too late. To their surprise, Kotaro suddenly leaped across the room with one jump. The tanuki transformed into a massive club, swinging himself to land a hit across the enemy's jaw.

"I-Incredible!" Shinobu gasped, watching Kotaro morph back to normal with a jingle of his bell.

"What kind of tanuki could possess such power?..." Yamato gazed at the animal in wonder, sheathing back his mace behind him.

"In any case, you can put your mind at ease, Momonosuke-sama. The enemies were taken care off"

"I am not okay, I feel bad" the child brought his head out through one of the sleeveless hole. "I cannot do anything except rely on others for protection...I hate myself"

"What are you saying?!" the kunoichi cried out at the frowning child. "It's natural for us retainers to be your sword and shield and defend you!"

"Everyone is overrating me!"Momonosuke snapped, nudging his face deeper into Yamato's back. "I...I am frivolous, stupid...weak, foolish, and I am sick of myself..."

"Even if you're small now, I know you'll be big and become a great Shogun one day!"

"You'll be a greater man than Kozuki Oden ever was!" Yamato added with a smile.

"....I AM NOT GREAT AT ALL!" the child cried out, coming out of Yamato's top in his dragon/eel form to the surprise and shock to the others.

"GAH! AN EEL?!"

"This is what he becomes when he gets excited" Shinobu explained.

"Could it be because you ate a Devil Fruit?" Yamato wondered. "You look like...my father!"

Once Momonosuke calmed down, he returned to his normal form of a child and hid once again inside Yamato's clothes.

"It may not look it, but I have gained better control over it...When I first met Luffy and the others, I would turn into a dragon every time I got surprised and felt sad" the boy explained.

"I'm astonished. I wonder if it's similar to my father's power..."

"If I could turn into a monster like he does, I would be of some help to everyone..."

"Luffy is still fighting Kaido, right? I wonder if he's okay! I wanna take down Kaido too! As Oden!" Yamato exclaimed.

"Luffy is getting much weaker...But somehow he is in good spirits!" Momonosuke answered.

"That's good...? Wait, how can you tell, Momonosuke-sama?!" Shinobu asked in disbelief.

"I...I'm not sure. And it's not only Luffy, there's also...I feel like something is lurking here. Something that is making my skin crawls"

Kotaro's sudden growls interrupted Momonosuke, and all of them gazed at him. The tanuki was glaring at the ceiling, in a particular spot where no light could be cast. Shinobu and Yamato's eyes widened when they caught sight of a single red eye squinting at them.

"We can't stay here!" Yamato yelled, bullets of sweat rolling down his forehead.

"Is this another one of those Marys?!" Shinobu asked.

"I never seen that thing before!"

They quickly took off while the eyeball's gaze followed them until they disappeared around the corner.
