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?)

Without any suspense, Usopp, Nami, Yosaku, Johnny and Liz consumed the fruit at the same time.
"Urgh! What kind of taste is this?!" Nami felt nauseated after taking one bite. Not only her but the other's faces also turned blue as they became disgusted by it.
"The more you consume, the more your power of the Devil Fruit grows." Luke smirked. His eyes were squinting in deviousness.
"I feel like puking after eating half of it." Usopp's face was turning purple every second past.
Meanwhile, Yosaku and Johnny finished consuming the Devil Fruit while having purple faces.
Liz on the other hand was trembling. She just bit the fruit twice and she's about to give up on it.
"Is this really normal?" Sanji pointed at the dying faces of the group.
"Yes! I ate mine without leaving anything and the taste was terrible!" Luffy recalled the time when he was with the Red Haired Pirates as he laughed.
"Oh right. Maybe I'm wrong. Actually you only need one bite to gain the entirety of the Devil Fruit's power." Luke was grinning from ear to ear as he finally revealed the truth.
"LUKE!! URGGH!"
Usopp and the others glared at Luke as they scattered to every corner of the ship to throw up to the sea.
Liz stared at Luke with teary eyed and full of cute indignation.
"I thought I was going to die!" Yosaku breath a sigh of relief as he laid flat on the floor together with Johnny.
Luke and Luffy laughed out loud by the scene.
Even Zoro and Sanji found everything so amusing.
"You! You clearly knew it in the first place!" Nami approaches Luke as she pinched his cheek.
RUMMBLE! BOOOM!!
Suddenly, Luke was strucked by lightning.
"AAAAH!!!" Nami was flown back from the recoil. She didn't know what just happened.
The Going Merry slightly swayed from the impact.
The rest of the group also got terrified by the sudden event.
Luke was still standing while an energy bubble engulfed his body. After releasing the bubble, he chuckled to ease the tension.
"Congratulations Nami, you gained the power of a God, the Rumble Rumble Fruit."
Everyone gawked at the revelation.
"This! This!" Nami got scared as she trembled in fear. Her power was so dangerous that she even felt scared by it.
"Don't worry. You only need to familiarize with your power. Soon, you'll get used to it-" Luke suddenly got interrupted.
"N-Nooo! I don't want this! I don't want to hurt any of you!" Nami broke into tears while shivering. Due to her unstable emotion, the dark sky suddenly rumbled while lightning danced around the cloud.
Luke went silent. He knew if he says more, the crew will definitely be in danger.
"Luffy, touch her." Luke turned to Luffy as he said.
"Oh sure." Luffy trusted Luke as he walked towards the ever scared Nami.
"N-No!! Get back! I don't want to hurt you!!" Nami wailed as she started to crawled back.
Tap!
Without hesitation, Luffy tapped Nami's head much to the horror of the crew.
CRACKLE!! BOOOOOM!!!
Luffy suddenly got strucked by thunder as everyone expected.
"NOOOO!!!"
Nami's heart dropped as she stared at Luffy in despair.
"..."
"Huh?" Nami was first to react when she saw Luffy was still fine.
Tap!
CRACKLE!! BOOOOOM!!!
Luffy tapped Nami's head again as he got strucked by another wave of thunder.
The power of the thunder was enough to roast an average man to death.
"..."
"Huh?" Once again, Nami got puzzled. She saw Luffy got strucked twice but he appears to be... fine?
"Yahahaha!! This is so fun!!" Luffy tapped Nami's head again, expecting for another thunder to come. However, nothing struck him this time.
"Huh? Where's the thunder? Nami, do it again!!" Luffy complained as he shook Nami's body.
CRACKLE!! BOOOOM!!!
Luffy was strucked again, but he was laughing as if he got tickled by the thunder.
Still, he was fine.
Just like Enel's expression in the original story, everyone except Luke and Liz copied Enel's famous shocked facial expression.
"Ahahahaha!! Amazing!! Nami! You have a wonderful ability!" Luffy laughed out loud ignoring the weird reaction of the crowd.
"A-Are you alright, Luffy?" Nami asked with concern.
"Of course I'm fine!! Your power actually give me tickles!" Luffy grinned.
Everyone stared at Luke as they were puzzled.
Luke almost blurted 'It's the power of love.'
After giving Luffy a thumbs up, he explained,
"Luffy's body is made of rubber. Rubber negates lightning by nature. Now that you have calmed down, everything has returned to normal." Luke pointed at the dark sky without lightning.
"So that's how it is." Sanji nodded. He was clearly terrified from the power of the Devil Fruits.
"If you are calm, anyone can touch you." Luke tapped Nami's head and he wasn't strucked by lightning. Actually, he was gambling that Nami's power won't struck him again or else it will be a total awkward scene. He'll probably call it a day and fled to Impel down to hide his embarrassing moment.
Nami indeed calmed herself down after she got affected by Luffy's goofy attitude.
Nami took a deep breath as she glanced at her hands while lightning sparks danced around it. Soon enough, she came to adjust her mood as she smiled in relief.
"Nami, your task is to control your power. You only need some meditation and you'll be good in no time." Luke assured Nami with an assignment.
Nami nodded seriously. Her power is just too terrible that she almost lost control of herself. Fortunately, there's Luke who guided her and also Luffy's light attitude that she's able to calm herself.
"Since Nami showed her prowess, who's next?"
"..."
"Bro Luke, you know we can't compete with Big sis Nami, right?" Yosaku whispered carefully.
"What do you mean? This is not about competition." Luke knocked Yosaku's head.
"It's fine if you don't show your powers. It's actually good that way. But be sure to control your powers especially when it negatively affects your fellow comrades. Am I clear?" Luke sternly warned.
"Yes!" Everyone who consumed their Devil Fruit nodded solemnly. They were excited to explore their powers. This will be a sleepless night for the group.
"Tomorrow will start the official training for Observation Haki. Dismissed for now. If you have any comments, concerns or violent reactions, just look for me anytime."
With that, Luke returned to the back of Going Merry which is his favorite spot to relax.
Everyone still remained as they chattered with bustling noises.
Sanji also prepared a feast for everyone to celebrate the increase of power of the Strawhats.
Luke smiled as he watched the Strawhats were having the festive vibe. Luffy, Usopp, Yosaku and Johnny danced around as they are like party maniacs. They played jokes and some weird shows too.
Zoro drinks his booze with a happy smile.
Sanji catered the ladies with food and wine.
Nami and Liz clapped along with the comedic antics of the four men.
Laughter and giggles spread across the seas as the party will probably lasts until the next day.
Luke took a cigarette out of his pocket. He felt nostalgia as he dazed at the night sky.
...
Morning...
East Blue, Logue Town...
"Captain Smoker, there's a report from HQ. A Vice-Admiral is on the way to pay a visit to our town." A young lady wearing glasses entered the office. She wore short-sleeved shirts of varying different colors and designs but covered them with her white-trimmed, waist-length blue leather coat. She wore dark blue jeans with black shoes but has also paired white capris with tan shoes.
Her name is Tashigi, Chief Petty Officer of the marines.
"Oh? That's not a surprise at all. Was it Garp? He visited this place quite often before." A muscular, white-haired and brown-eyed man, while smoking two cigars at once, glanced at Tashigi.
This man is none other than Captain Smoker of the marines.
"Well, yes. Garp-san will arrive here soon but to escort two Vice-Admirals." Tashigi adjusted her glasses as she read the full report on the paper,
"The first one is Vice-Admiral Tatsumaki who will settle down in our Town for a couple of days to monitor the safety of our people here. She's accompanied with Vice-Admiral Metal Bat to settle down on Shells Town with same purpose."
"Huh? What's going on? Why some bigwigs are settling here now?" Smoker got puzzled.
"Someone spreaded the news regarding prisoners of the Impel Down escaping a month ago. Apparently, various kings all over the world felt unsafe and requested to HQ a gesture of reassurance."
"Hmm.. So it's like that huh..." Smoker puffed a mouthful of smoke as he understood. He said,
"Then prepare a new office for our visitor."
"Right. There's another thing." Tashigi passed a paper to Smoker.
"...A pirate bounty?"
...
Bang!
"Hey! Watch it, jerk!" Zoro rubbed his forehead in annoyance.
"Zoro, that's Going Merry's mast post. You bumped it ten times already." Nami commented as she facepalmed by how terrible Zoro's sense of direction.
Zoro, Usopp, Sanji, Yosaku and Johnny started their training by getting blindfolded. Since they didn't found a ship to hijack yet, their task is to walk with twice or more speed as they roam around Going Merry without bumping to any obstacles.
Sometimes they bump, sometimes they fell off the ship, sometimes they fight. It's a total mess in actual sense with zero progress.
Of course Luke didn't mind it. If learning Observation Haki is as easy as eating a meal, then people around the world will thrive to become the Pirate King.
"YAHAHAHA!!! We're finally wanted now!!" Luffy laughed out loud as he presented to the group a wanted poster.
"I feel weird when you say it like that." Luke shook his head as he smiled wryly.
Zoro and others paused their training as they all flocked to Luffy.
WANTED! DEAD OR ALIVE!
