A/N : Majority voted on Non-Harem. However, Luke's nature pertaining to opposite gender is questionable based on his past records. (He likes playing around with women in his previous world.) He may also play around with women characters of One Piece but it also comes with valid reason since he's a man with complicated background. So he only need one woman to 'move' him or maybe the other way around. (Who knows?)

While Zoro and others resumed their training, Luke was in a corner, reading a report from Blackbeard.
Blackbeard indeed worked for the organization that lasted two weeks, after getting impatient, he escaped while roaming around the New World and collecting Devil Fruits along the way.
Luke didn't mind Blackbeard's little adventure as he focused more on what kind of organization that Killer Bee worked for.
He does found little valuable informations. Like the main base of the organization was located at the bottom of the calm belt in the new world, near Elbaf Island. The base was also like a country under the ocean.
Blackbeard tried to excavate more information, but the key members were in tight lipped about it. With little more patience, he finally found something.
The organization was hiding from the prying eyes of the Celestial Dragons. They're making plans to make a comeback soon and challenge the World Government's authority.
Aside from those, Blackbeard listed some descriptions of key members of the organization which Luke easily guessed as the nine individuals having tailed beasts inside their bodies.
'A country under the ocean huh... They're not even afraid of sea kings?'' Luke thought as he envisioned the place might look like Konoha in their story.
What bothered Luke was that, Celestial Dragons may have something more than what it has from the original story.
'What now? Goku became a Celestial Dragon or something?' Luke groaned as the world was complicated than ever.
'If Naruto is here, then he can contend from the likes of Kaido, but he didn't. They stayed hidden because someone or something that's more powerful are watching at their actions.'
'Whatever. Go fight those Celestial Dragons up there. It's a good thing anyway.'
Luke shrugged as he throw the idea in the back of his mind.
"Marines!"
"Hm?" Luke glanced at Nami who suddenly shouted.
Everyone immediately stopped doing their training as they surveyed the seas.
"Huh? Where?"
After not finding anything, everyone stared at Nami at the deck in confusion.
"Up front! Look!" Nami pointed forward.
"Hm?" Usopp used his eye telescope as he indeed found a little dot in the distance, but it's too far that he was having a hard time guessing if it's an island, rock formation, a pirate ship, or a marine ship.
"Oy Nami. How'd you know it's a marine ship? It's too far!" Usopp inquired with puzzled look.
Everyone except Luke also stared at Nami with curiosity. Does Nami hid a telescope while trying to tease them?
"Hehehe! I just know!" Nami stucked out her tongue while enjoying the various reactions of the crew.
"Perfect timing! We hijack that ship!" Luffy grinned as he flexed his muscles. He was bored and wanted to train his bones with Luke.
Luke squinted his eyes as he glanced at the marine ship. From what he recalled in the original story, it should be the ship of Lieutenant Fullbody of the marines.
Soon enough, both ship met as Luffy and the crew unceremonously smacked Fullbody and his crew black and blue.
When the marines were about to flee, Luke froze their bodies.
Everyone glanced at Luke in confusion.
"Tie them up first. I have a better plan regarding your training." Luke approached the group. He also commanded to ransack the valuables of the ship before the training begins.
The marine ship wasn't towed as both ship sailed side by side.
"Do you know what you're doing?! You're all dead men for kidnapping marines!!" Fullbody took a tough front as he shouted at the Strawhats.
"Shut up! We're pirates. Of course we are opposing the marines." Sanji knocked Fullbody's head.
"Listen up. I'm going to level up your training now." Luke said. He continued, "Zoro, Sanji, Usopp, Yosaku and Johnny, you guys go to the marine ship and resume your blindfold routine. Also, drop your weapons here in Going Merry and no one shall use their Devil Fruit powers to cheat."
Zoro and co was puzzled but they did what Luke said.
"As for you guys.. You have one job." Luke glanced at Fullbody and the other five marines with mischief.
Nami and Liz felt that Luke was up to something bad so they paid attention to it.
Clank! Clank! Clank!
Zoro and others were about to blindfold themselves when they saw Fullbody and his men holding wooden clubs.
"W-W-What's the meaning of this, Luke!?" Usopp shivered in fear as he saw the marines giving him menacing glares.
"Alright. Here's the mechanics of this training. These guys here will attack you with clubs until you go unconscious."
"Your role is to use any space of the ship as your hiding spot. Evade them, block them but don't attack back. Feel your surroundings. Feel the danger and you'll achieve Observation Haki in no time."
"Danger comes opportunity. This is your chance."
"You can choose to remove your blindfold, but you also remove your opportunity to get stronger."
"Get ready!"
After Luke finished his speech, he waved at Fullbody and his men to start.
Yosaku, Johnny and Usopp sweated in fear. They were hesitating if they should wear a blindfold or not.
Meanwhile, Zoro and Sanji just gritted their teeth as they blindfolded themselves and focused on their surroundings with full caution. This kind of training indeed gave them thrills than just walking around.
"Hooo! This brings back memories!" Luffy watched the scene with interest as he laughed.
"Yeah. Let's see who can achieve Observation Haki first."
"I vote for Zoro! 100 thousand berries!" Nami immediately smiled as she acted her mischievious nature.
"OHH! I choose Sanji!" Luffy also played along.
"Hey! I'm better than this green head over here! Nami chan! Choose me instead!" Sanji heard their conversation as he shouted while being chased down by Fullbody.
"Ah!? What did you say, you curly brows?! Do you want a fight!?" Zoro got annoyed when he heard Sanji mocked his hair color.
"Okay. I'll choose Usopp. 100 thousand berries." Luke said as he also gambled with Nami.
"I-I don't have money. But I'll go with Zoro." Liz smiled as she also picked Zoro.
"Nani!? Liz chan! You should pick me too!!" Sanji was annoyed that the ladies didn't pick him.
"Shut up, idiot! Focus on training!" Zoro ran around while feeling the danger in his surroundings.
"You shut up, moss head!" Sanji barked.
Meanwhile, Yosaku and Johnny were crawling inside the cabin as they escaped the scene. Sooner or later, they will gonna be caught by the attackers.
Usopp was shivering in fear as he swayed left and right as if someone attacked him when there's none.
That's because, all six men were focusing their attention on Zoro and Sanji.
"Hahaha! Look at Usopp! He's so funny!" Luffy commented while rolling on the floor laughing.
"Shut up, Luffy!" Usopp shouted back at Luffy.
As the men continues their training, Luke and others made comments once in a while.
...
Dusk...
"Stop. That's it for now." Luke announced as the first day of training ends.
With no exception, all men dropped to the floor while fully exhausted.
Johnny, Yosaku and Usopp had long been down while Zoro and Sanji persisted until the end.
Fullbody and his men also dropped from exhaustion. Apparently, they can't take down the two men in training.
Sanji was full of bruises as he shakily stood up and went to clean himself since he's preparing for everyone's dinner. He still kept his blindfold as he decided to go tough on his training. Even in cooking, he will also do it while in blindfold.
Luke nodded as he admired Sanji's dedication.
"Say Luffy. How long did you achieve Observation Haki?" Nami asked Luffy. She clearly saw the harsh training of the men as she also felt pity for them.
"Me? Hmmmm.. five days and I can barely evade three out of ten attacks. But Zoro and other's training are harsher than mine so they may be able to master it in five days time." Luffy thought out loud.
"Should I heal them?" Liz asked Luke in concern.
"Not yet. Let them get familiarize this feeling for a while. It will help them grow in training." Luke waved his hand. Fortunately, they have a healer around or the training will probably lasts for a month.
The men were totally black and blue since Fullbody and his men didn't show mercy on them.
"I'm thirsty. I want my booze." Zoro stood up with his shaking body as he went to the kitchen while still in blindfold.
"You get more dehydrated if you drink that." Nami warned.
It took Zoro a while to reach the kitchen as he circled around the ship with his bad sense of direction.
"Let him." Luke smiled. He could tell that Zoro was fired up. These men are starting to glow up like in post-timeskip in the original story. He will soon see some badass moments after their training.
"Now then. Luffy, your turn next after dinner so be prepared." Luke turned to Luffy.
"Of course!" Luffy's eyes shone with excitement.
