One piece : Celestial Rose

Mark exhaled and stretched his body, he loosened himself and explained his actions a bit so that Sengoku can co-operate with him.

"I came down to the lower realm to experience life and gain strength."

"I hope you two veteran fighters can help me train a little."

"What do you say? You fight me and I let them go, not a bad deal right?"

Everything came to a standstill when Mark said this, normally someone wanting to fight against the fleet admiral would be weird but possible, but Mark wasn't someone normal.

He was a celestial dragon, even thinking of attacking one of them could get people killed, much less fighting one.

Sengoku also realised the trouble they were in, but he also knew that they can't escape, Mark was already doing this because he begged him personally.

Now Sengoku and Tsuru were having a headache, they didn't know how to fight Mark in a way that dosen't hurt him.

Who's who meanwhile was laughing from the side, he was the only one here who knew Mark's plan, Mark had already told him that he was going to get Smoker somehow.

Smoker might be incredibly weak right now, but the smoke logia he had was not weak, it was a very deadly weapon when used correctly.

So Who's who didn't say anything and played along with his boss, they will get Smoker and then they will train him so he could unleash the full potential of his logia.

"Saint Mark, can we not fight.."

Sengoku meanwhile asked helplessly, although he knew the answer even before asking, he was already sensing the fighting spirit from Mark.

Mark was unleashing his conqueror's haki which was growing in intensity each second.

Even the most trained CP agents had their postures broken by his conqueror's haki.

"No we must fight."

Sengoku saw Mark giving a smile, then he heard one last word before he felt an a lot of pain in his chest as Mark's kick made contact with him.

"We must fight and we must do it now!"

*Booom*

The Marine headquarters shook as Sengoku's body crashed into a thick wall, breaking it apart upon impact, smoke and dust emerged from the broken buildings.

'Lord Mark is much stronger than I thought he was! His physical strength is off the charts!'

Who's who was sweating buckets after looking at the destruction before him, Mark might not have a devil fruit backing him up like Sengoku, but he surely packed a punch.

Who's who then saw Mark cracking another big smile, the ground beneath him started shaking, his eyes went white and his hair was starting to flow without wind, his muscles bulked up and so did his height.

Mark activated life return and changed his body into a much larger from to fight against Sengoku and his mythical zoan devil fruit.

Mark now looked like Broly, the strongest and most muscle bound Saiyan in existence.

"Saint Mark please calm down, this is the Marine headquarters."

"We can fight somewhere else, maybe on some abandoned island."

Tsuru immediately ran infront of Mark and put her hands forward, she was also one of the big three, Garp, Sengoku and Tsuru.

She didn't know how she was supposed to fight Mark without taking the risk of hurting him, but she knew that just defending against his attacks was always a good choice.

She can't hurt him if she never attacks him!

Tsuru was sure that she could even stop Mark if she wanted to, all she will need to do is touch him once and Mark would lose.

Her wash wash fruit was powerful, she could wash away evil from people's hearts, she was confident that she can wash away Mark's desire to fight.

"Hmm?"

Mark turned towards Tsuru, his pupilless eyes frowned but he gave another big smile and immediately vanished.

Still, Tsuru wasn't caught off guard like Sengoku, she knew it was coming!

'Wait, this speed! It's shave, when did Saint Mark learn shave!'

Tsuru's eyes dilated, she was infact caught off guard when Mark suddenly used shave.

Realising the trouble she was in, she somehow managed to put her hands in a defensive position.

*Boom*

And immediately felt her bones rattle, she too was kicked away and crashed into a building, breaking it apart.

Rubble was flying everywhere, Who's who dodged a stray rock flying his way, he understood this was a war zone now, he needed to be run away from here.

"Marshal! Don't pretend to be dead, fight lord Mark seriously!"

But before running away, Who's who decided to expose Sengoku's acting.

He quickly turned into a saber tooth tiger, hybrid form and prepared to run.

Although the ruins where Sengoku fell still didn't have any movement, but Who's who knew he was there, this was the Marshal, not some random mook.

"If you don't fight seriously and it makes Saint Mark angry, you'll take all the responsibility Sengoku!"

"So go! Fight Lord Mark! Give him the training he wants!"

Hearing this Sengoku smiled helplessly at the crater he was sleeping in, he knew he had to fight somewhat seriously now.

Immediately a bright golden light emerged from the broken buildings, rocks started crashing down and a big golden figure emerged from the rubble.

*Vooom*

Sengoku's golden face was visible to everyone, his now gigantic gold body stood amongst the ruins.

Feeling the danger of Sengoku's mythical transformation, Mark slowly turned towards him.

'I can't fight someone this strong like I am now, I need something else.'

'I need more power.'

Mark realised this and his body responded with life return, he too started growing in height just like Sengoku.

The stored nutrients in his body were used up rapidly, his now massive body was filled with raw power and dense muscles.

This was his answer to Sengoku's mythical transformation, he will counter Sengoku with sheer raw strength.

He didn't know armament haki, this was the only way he could fight Sengoku without losing right now.

"Time to run."

Who's who muttered and immediately ran towards the cafeteria, he understood this place was about to become warzone.

Everyone in the headquarters was afraid but he was calm, he knew his lord wouldn't hurt him.

His lord even gave him a signal to get away from here a while ago.

So Who's who did exactly what Mark told him to do, run away! 

Anyway a fight was about to happen he didn't want to be a part of it.

Sengoku vs Mark.

This was about happen.
