Animeverse Slayer!

Years ago when demon slayers awakened their 'Breath', each of them gained an attribute connected to their breathing techniques.

Rengoku obtained explosive power, Gyomei got powerful defence, Uzui got sonic power, Iguro obtained muscle dexterity... however Shinobu's 'Breath' only gave her the base benefits, accelerated healing.

Only years later did she accidentally find the peculiarity of her 'Breath'. She was able to absorb energy from vegetation.

Every time she absorbed energy her 'Breath' got stronger, and it would absorb a part of that energy's attribute.

In this manner, when she absorbed several poisonous herbs her 'Breath' also absorbed it's poisonous trait. Her 'Breath' was special, it was unlike like Leo and others whose attributes were physical.

She is able to combine her 'Breath' with drugs and increase it's potency by several fold. If it's a healing drug then it would become an incredible cure, if it's poison then it would become a devastating calamity.

Oven, Amande and their men didn't know this. They fell head first into the grinder.

"Alright, let's go."

Shinobu picked up the bag with the plant and walked away. The crew took a second to snap out of their daze. They trembled when they saw dead bodies everywhere and quickly caught upto Shinobu.

After they walked out of the forest Shinobu ordered the men to count how many enemies were dead. She got an answer very quickly.

35 pirates were killed!

Shinobu simply looked at him once and went back to the ship.

The whole island was blocked from outside communication. The crew ran around and after two hours they were able to take care of that problem.

"Ma'am, are you alright!?"

As soon as the connection was restored Mace yelled through the den-den mushi.

Shinobu held the receiver far from her face, only after the voice died down did she speak.

"I am fine, why would I not be?"

"Haha, I told you didn't I?"

She heard Leo's voice and said, "There are a lot bodies here."

Leo grabbed the receiver from Mace and said, "Don't worry. I have send some people to take care of it."

"Ok. Seen you soon."

Kachak!

The call was cut. Mace sat down in a daze.

Leo curled his lips and said, "What did I say? No one can get close to her without getting poisoned to death, much less capture her, haha."

The news of Shinobu killing one of Big Mom's officers and 34 pirates spread quickly.

When Sengoku got the news he was shocked. He never expected that charming lady to be so vicious.

She poisoned 35 people to death!

He was overwhelmed when the heard the news however he broke out into a laugh later.

He didn't pick up a single treasure but two!

Since Shinobu had shown her capabilities he had no problem raising her rank as well. With that Shinobu's rank was raised to a vice admiral as well.

New World, Totto Land, Whole Cake Island.

Big Mom was raging through her castle. She destroyed everything she could get her hands on.

No one stopped her, no one dared to.

"Leo Heart! Kocho Shinobu! Aaaahh!!"

She howled and banged her fist on the ground. Cracks spread through the ground like a spider web and caved in.

For several hours Totto Land was shaking from her anger.

...

Leo was walking through the sandy beach of the island. He enjoyed the cool breeze from the sea and the constant waves splashing on his feet.

Just as he was in the midst of his walk he sensed a sea king far in the distance. As he was about to take walk away he paused and raised an eyebrow in surprise, a peculiar light shone in his eyes.

He used Geppo and rushed towards the sea king.

The sea king sensed Leo and opened it's mouth wide to take a bit at him.

Leo used his palm as a sword and slashed it down. The sea king paused midway and was sliced into two. As both half of it's body sunk into the water he sensed a small presence slip out of one of the sliced half.

He waited up in the sky and soon that presence swam back to the surface.

It was a woman, she had short hair and wore a sleeveless shirt. However she didn't have legs but a fish tail!

A mermaid!

This thought came to his mind.

Leo smiled and said, "Hello."

The woman was stunned she subconsciously replied after hearing his polite, "Hello."

Leo chuckled and asked, "How did you get eaten by it?"

In response to his question she laughed dryly and avoided the subject.

"Thanks for saving me."

"It's alright. My name is Leo."

The woman said, "My name is Cami."

"Are you heading back to Fishman Island?"

The lady nodded, "Yes."

Leo's eyes sparkled, "Can you bring me with you?"

The woman didn't mind and said, "I can but you have to first coat your ship otherwise it's impossible to dive down."

Leo have heard about this before. He nodded and said, "Give me two days. When my wife comes back we will immediately set off to Sabaody Archipelago."

"In the meantime you can stay here. I will arrange for your accommodation and meals."

Cami waved her hand hastily, "No, there's no need. You saved me, I can't ask more of you."

Leo shook his head, "It's fine. You are my guide, it's rude of me if I don't take care of you."

Cami reluctantly agreed. Leo got back and ordered the ladies in his crew to take care of Cami.

When it was close to evening Shinobu came back. She was startled when she heard about a mermaid.

She immediately went to the shore and made acquaintance with Cami. They talked for a while about irrelevant topics and when it was time for them to set sail Shinobu and Cami seems to have gotten close to each other.

The ship set sail when the sun was going down the horizon.

Fishman Island, here I come.

Leo smiled and said to himself.

...

Somewhere in New World.

"Kaido-sama, his ship has set sail towards Sabaody Archipelago."

Kaido who was listening to a pirates report snorted.

"That kid made a name for himself by taking out Linlin's crew. Hmph! Tell Jack to bring his head back!"
