Animeverse Slayer!

A vein throbbed on Leo's forehead.

Just as he was wondering whether to give Garp a 'welcome kick' he sensed a person coming out of the forest into the open field.

It was a young man. Many of Leo's crew gasped when they saw who it was.

Mace who was standing next to Leo muttered, "So this is where you were, 'Fire Fist' Ace!"

Ace saw the visitors and was slightly surprised. He nodded to them and gave Garp a kick to his head.

"Smelly old man, there are marines here to visit you!"

Guhah!

Garp was thrown off the ground. He grumpily woke and roared at Ace.

"Which grandson would kick their grandfather so ruthlessly?! Was my care and love wasted on you?!"

Ace smiled with disdain, "Care and love? You threw me and Luffy to fight against wild beasts and left us alone inside the forest for days! Care and love, my ass!"

"What would you know?! That's called training!"

Listening to Garp Leo doubted if it was a wrong choice to leave Coby's training to him.

Coby seems to have gotten immune to their bickering as he continued to train with focus.

Leo walked up and pulled away the grandson and grandfather duo who was about to fight it out and said, "Have some manners when you have guests."

Garp scoffed and went towards the marines. He grabbed the equipment they were carrying and checked them.

Leo watched the extremely focused Coby and nodded. If he doesn't have this much determination then Leo chose wrong.

After an hour Coby got up from the ground while trembling. He squeezed out a smile and said, "Sorry about that."

Leo smiled, "Don't worry kid. Focus is a key aspect in training, keep it up."

Coby sat down and closed his eyes. Before long he dozed off.

Leo had his doubts about how these three men took care of their meals, however he was relieved when he met a fat woman named Dadan.

She was a bit rude but she was kind to Ace and Coby.

When night fell Garp and Leo found a silent corner and started drinking.

"Will the kid be alright?"

Leo asked.

Garp took a swing from the bottle and said, "He can handle it. Rumble-Rumble fruit has high destructive power, if his body ain't strong enough he would burn out."

Hm.

Leo hummed. He took the bottle from Garp and said, "Ace seems to have m.a.t.u.r.ed a bit."

Garp sighed slightly, "Going through all that, who wouldn't? I am just glad he is alive."

Leo finished the bottle and got up, "Don't worry, the day will come when he can walk freely without being called the son of an evil man."

He walked away saying that.

Garp glanced at him deeply for a moment before shaking his head, he continued to drink his worries away.

...

"Fire lance!"

Ace spread out his arms, flames condensed and formed two lances before flying towards Leo.

Against the incoming flames Leo stood tall like a mountain and waved his sword.

Sword rays danced around him and chipped away the flame lance. In an instant the flames were dispersed.

Ace raised his arms and pointed his index fingers at Leo.

"Finger pistol!"

However like before they couldn't reach him. The flames were slashed and dispersed by his sword rays.

After half an hour Ace backed up and said indignantly, "Your sword is annoying."

Leo grinned, "Now, do you understand human potential? Devil fruits are great, but the potential of our bodies are no weaker. You have developed several techniques for your fruit but you still haven't developed it's core concept, nor have you unearthed your body's potential."

Hearing his lecture Ace scoffed and walked away.

Leo smiled and shook his head. Kids nowadays are so troublesome.

He sheathed his sword and got back to the house to check upon Coby's training. However, he was shell shocked at what he saw.

Coby was chained with kairoseki and each of his limbs were tied with a particular material that was ten times heavier than it's original body.

So right now Coby was tied with atleast 500 kg on each limb. Along with the powerlessness from kairoseki it's a miracle that the kid could even stand.

"You damn old man!"

"Ah, Leo, come, sit here. It's quite relaxing under the shade."

Leo nearly cursed out.

"This might kill the kid."

Garp said nonchalantly, "He doesn't have great talent, if I don't dig out his potential he will remain weak."

Leo wanted to say something, but in the end he knew Garp was right and could only hope Coby won't break.

"I am leaving today."

Garp nodded, "Alright, thanks for bringing the stuff."

Leo waved his hand, "Yeah, yeah, happy to help."

He got up and waved at Coby before leaving the mountain.

Without further ado they left the island.

...

The warship was docked on an island to gather supplies.

Leo was walking around and saw a casino. His interest was piqued, he stepped inside and saw crowds of people seated around tables yelling their hearts out.

Gambling is the same everywhere.

He said to himself and got to a table.

He looked at the other participants. There were three men wearing luxurious clothes and ornaments. The last one was a blind man with a cross scar on his face.

Interesting.

Leo's spiritual sense trembled slightly as it swept past the blind middle-aged man and he smiled.

"Black."

The middle-aged man said a single word and waited.

The roulette spinned for several seconds and came to a stop.

"Black!"

The middle-aged man won.

Leo was slightly taken back and looked at the bind man with a serious look.

The extremity of kenbunshoku haki. Who would have thought I would meet someone like that here.
