Demon lords Voyage! (Tensura X OnePiece)

The Beginning

"By haki do you mean this?"

Dagruel said as he clenched his fist while coating it with armament haki that turn his hand into jet black color

"Woah!! How did you do that?! It's not even a day since we arrived in this world!"

Milim said in astonishment.

But soon, Guy, Leon and Rimuru also coating their hand with armament haki and showed it to milim

"Well, after we received the basic information from rimuru regarding this world, we just instinctively capable of doing it. Oh including observation haki and conqueror haki"

Guy statement suddenly make luminous, milim, dino and ramiris frown noticeably. Since four of them also received the basic information, but they can't do it

"Don't be discourage, Guys is a demon who known to be excellent at magic manipulation so it's normal. Leon on the other hand is a otherworlder so of course he have seen this haki thing more than once. In dagruel case his original body is an ultimate organism so doing something like strengthening is easy for him"

Rimuru explain to those four depressed looking idiot, yes including luminous.

"Then, what about you?"

Ramiris asked

"Me? Well, as you guys know i'm a genius ."

Looking at rimuru smug expression, luminous seem to got pissed of for some reason

Dino seemed to want to say something, but milim quickly dragged him to train somewhere else, and just like that the four of them dissapeared from the place

Rimuru then say to the other three that he has something to do and leave them

*

A month later

Many things has changed during the time when the octagram spend their time in sabaody island

Milim, dino, ramiris and luminous haki training also has finally paid off. The most impressive of the three is obviously milim who mastered both ryuo (advance armament haki) and future sight (advance observation haki)

While luminous is also a monster too since she able to learn future sight in a month, but unfortunately her armament and conqueror haki still stuck at the peak of first stage

Ramiris and dino meanwhile just mastered all three basic haki without any advancement

Rimuru, guy, leon and dagruel on the other hand managed to master all three haki in advance form

'phew, our ship. The black pearl finally finished!! Thank you for your hardwork during all this time ciel!'

<<It's my eternal pleasure to be of use to you master>>

Rimuru just smiled sweetly as his gaze is still locked on the majestic medium size ship in front of him.

All the material on the ship is fully coated with the armament haki and with ciel excellent modifying the material on the ship turn into black permanently, further boosted the ship endurance

'i need to tell them about this!'

Rimuru thought as he quickly went to search of his friends

Meanwhile luminous who has just done with her daily training just came back from her usual treasure raid

As she keep walking she noticed a lot of civilians is kneeling on the both side of the road

'----except for me and that green hair guy, all the peoples is kneeling. What happen?'

Luminous mutter in confuse, but decided to ignore it and keep walking

But soon, she found a man with astronaut-like outfit is looking at both her and a green hair man beside her with shocked expression

'--?'

All the civilians also put on a horrified expression while seeing those two

"What? Are you lost? Want me to give you a direction?"

The green hair man said non-chalantly toward the astronaut looking guy, the guy suddenly point his pistol and try to shoot the green hair man

But the man dodge the bullet with a smile snd ready to cut down the astronaut looking guy

'i see now. So that's a celestial dragon, and that man is Pirate hunter Roronoa Zoro. This is the event that milim has been talking about'

Luminous finally clicked the pieces together and roughly know about the situation

'Well, it's not our time to be involve yet'

Luminous thought as she silently walk away from the scene, but then--

"That woman is pretty. I'm gonna take her as one of my wives"

The celestial dragon said while pointing toward luminous

"Yes. I shall put her on registry as your lady 14 sir"

The celestial dragon guards then grabbed luminous's shoulder and grab her strong enough so that she can't break away

The celestial dragon then smile disgustingly as he approached luminous with his sweaty pig face

"You gonna served me well tonight~"

Luminous who earlier thought to not interfere with the current event completely changed her thought

'I'm sorry milim, but we gonna face admirals sooner or later right?'

Her beautiful face slowly turn colder and colder every second, the bloodlust she emitting is nothing the civilians or pirates here has even seen before

That's right, The Queen of Nightmare is furious!
