Hey there, everyone and Happy Belated Halloween! It's Warmachine375 again and I have made another Nanatsu no Taizai crossover story, this time with One Piece, titled as "Nami's Grace".
Oneshot just in case.
Synopsis: "On the brink of death from the Kestia bite infection she had suffered from, Nami finds herself meeting Sariel of the Four Archangels and made a pact with him to heal her body and become the host of his hibernating form in exchange.

Chapter 1
"What is this?... Where am I?..."
Nami wondered to herself where she found herself floating in the void of darkness. She looked to see there is nothing around here but herself. It is quite unnerving to be alone in the dark. The navigator/unofficial quartermaster of the Straw Hat Pirates tried to remember what happened and how did she get here. Oh right, I got terribly sick and I was dying. Luffy and Sanji were taking me to a doctor in Drum Kingdom. Some kind of witch the leader of the townsfolk were calling her if I recall..., she realized.
Then it gave her a cold chill down her back, fearing that her friends apparently failed in trying to get her illness treated on time and they were too late to reach the last doctor on time. "Am I dead?...", Nami wondered out loud.
"Not yet. You're on the brink of dying though...", a voice of a young boy called out to her.
Nami turned to the source to see a child whose body is glowing white light. He has light blue hair with bangs covering most of his forehead. He possessed four angelic wings on his back, the second pair smaller than the first. On top of that, he wore a set of coat-like robes with a triskelion symbol in his chest, his hoodie resembled that of a halo along with a pair of shoes and black shorts underneath his clothes.
She also noticed that he looked like he had been completely disintegrated apart into shreds, which he was in the middle of regenerating his body albeit very slowly. It made Nami grimace at the implications behind his current state in the first place. And not only that, he doesn't seem to be concerned about it at all in the slightest, acting like it is more of an inconvenience.
"Wh-who are you? Are you an angel?", Nami asked with curiosity even though she wasn't much of a religious person herself.
Not after she watched her adoptive mother Belle-mere die by Arlong's hand, the entire people of Cocoyashi Village suffering including her surrogate sister Nojiko and her father figure Genzo at the hands of the Fishmen oppressing them, and she had to steal enough 100,000,000 Beris by whatever means necessary in order to pay the Fishman captain for her home town's freedom before she was screwed over by the latter with his accomplice, corrupt Marine Captain Nezumi and his goons confiscating the money she saved up.
Until her salvation came in form of Monkey D. Luffy and the Straw Hat Pirates who defeated Arlong and his crew of Fishmen, and freed Cocoyashi Village, along with her cathartic payback on Nezumi to make him return the money.
"Goddess Clan member to be exact. But yes, I am one if it reassures you.", the blue haired boy clarified before introduced himself despite incomplete form. "The name is Sariel, one of the Four Archangels and holder of Tornado. And what is your name, milady?"
The Straw Hats navigator replied, "Nami. Uhm, not to be rude but what happened to you?"
Sariel frowned as he raised his right hand in partial regeneration and answered in response, "Oh this? Nothing to worry about, Lady Nami. I recently fell in battle against a... powerful foe. It was one of the hardest fights I had in my life. Not the one that I enjoyed. ... But as long as I possess my Grace, I will eventually revive. Although it takes time..."
"Grace?", Nami wondered out loud while she thought. So there are abilities that aren't Devil Fruits. Then again, if I probably not mention that to his face. Angels and Devils are obviously opposed against each other. I'm not pulling a pin on that grenade.
"The divine power bestowed to us Four Archangels by the Supreme Deity, our esteemed ruler of the Goddess Clan. That's about it. But enough about me, what happened to you?", the Goddess Clan member asked in turn, throwing back the question at her.
Caught off guard of Sariel's bluntness, Nami reluctantly answered. "... Uhm, to tell you the truth, I got sick after catching some kind of fatal disease from Little Garden. It felt like I was burning hot over inside out. My friends were trying to find a doctor to cure me."
"Huh? I see, you're the second person who had a fatal disease I've met.", the Tornado Grace holder remarked with a de ja vu look, which got the orange haired young woman's attention.
"Second? Who was the first?", Nami asked the angelic-looking boy in wonder.
"Solaseed. A bard with a lute. She got caught with a fatal illness before I met her and healed it away. When I left her, she was good as new.", Sariel stated.
She commented, "And you cured her with your Grace?"
Sariel corrected with an amused look, "Yes I did, but it's not Grace to be exact, Lady Nami. I used Ark, the inherent power of the Goddess Clan. Holy light that heals away any sickness and injury."
Knowing that she was on the brink of dying, Nami decided to make a humble request, "... Can you please heal me, Mr. Sariel? I don't want to die...".
After all, she had so many things to do with her life now free from Arlong, including pursuing her dream of drawing her map of the world as a member of the Straw Hat Pirates. And that she doesn't want to leave her friends behind and meet her adoptive mother Belle-mere in the afterlife. Friends who had saved Cocoyashi Village from Arlong and his crew and they had risked their lives to bring her to a doctor in the snowy dangers.
Even though she was unsure if Luffy and Sanji succeeded or not, but still hoped that they did make it on time.
Plus it is not like she could try trick an angelic being without consequences while being on the brink of dying.
After having some contemplative thinking, the member of the Four Archangels responded, "Sure thing, Lady Nami. I'll heal you. I might have to ask your consent though. It gets a little lonely here to be honest. Having to wait for an awfully long time to fully regenerate in this void. It didn't help I couldn't find any sign of Tarmiel and Ludociel here either."
Wait a minute, is that how he healed Miss Solaseed?, Nami thought in realization.
Catching on to what he is intending, she pointed out to Sariel, "Consent? Are you going to possess my body?"
"Yes.", the blue haired angelic being bluntly said. "However, considering my current state, I will have to hibernate within you. Until my body is fully regenerated and I will leave yours behind. On the bright side, you will get to have full access to my abilities while I sleep."
"... And what's the catch if I consent? Because I don't believe in free lunch.", the orange haired young woman asked with narrowed eyes, being on guard as she knew that nothing comes for free at all and there is always a price to pay no matter how benign it was.
She learned it all too well from her upbringing and experience.
Noting that the human girl is smart and cautious, Sariel answered with a somber tone, "... Well, the catch is that human bodies may have difficulty hosting high-ranking Goddesses such as myself, leading their bodies to undergo transformations. The compatibility between the vessel and the Goddess can affect its overall strength though."
"So basically my body will transform every time I use your powers?", Nami questioned with a worried face, wondering if she could mutate to have angelic wings like Sariel. At least I hope so..., she thought.
"You will just age up up to your prime and peak of your life, not into a shriveled up old lady if that's what you're worried about. My previous host Solaseed was a little girl before the overuse of my magic had turned her into an adult.", the Tornado Grace wielder reassured. "Not only that, you will get to have your own Ark power after a long period of possession. You will just have to train and make it your own power though."
That does sound enticing. At least I might get something out of it., the female Straw Hat internally noted.
Weighing her pros and cons before her for a minute, Nami eventually made her decision. "Alright, I consent, Mr. Sariel. So how does this work?"
"A handshake will do.", Sariel simply said before lifting his right hand, which Nami raised her right hand in turn.
The two made a handshake, showing that the pact has been sealed before the two were encased by a glowing bright light that brightened up everything around them.
On the room within Drum Castle
Regaining her consciousness, Nami slowly opened her eyes to find herself lying in bed with thick blankets covering her body that is clad in pajamas and a bag of ice cubes that was being placed on her forehead. Did it work? It was so surreal meeting an angel on the brink of dying. I feel a lot better though. Much better. But was it a dream?..., she wondered in her thoughts.
Then she felt something emanating from her body no longer afflicted by the illness she got from Little Garden. It felt... divine. Almost like she can command the winds and the holy light. The winds she possessed compatibility in sensing them with as part of her profession as a navigator to predict the weather and guide the Going Merry on sailing through the unpredictable seas of the Grand Line with the Straw Hat Pirates.
The power of Ark and Sariel's Grace, Tornado.
She realized that she's now the host of Sariel of the Four Archangels.
Nami corrected herself while remaining perfectly still on bed, Definitely not a dream. Sariel said he is going to hibernate within me and properly reform his body after I accepted the pact with him. I better need to make sure I don't overuse the Ark and Tornado Grace or else I might get the side effects. Oh my God, how am I supposed to tell everyone how I got these powers?
She mentally chided herself for not knowing the most obvious simple solution, Oh right, I can just say Devil Fruit and they will accept it. It's the only logical explanation in the Grand Line. It's not like there are people with angel wings living here. Maybe?...
Then the orange haired young woman overheard several footsteps and got out of the cover sheets to confront the person before her. "Who's there?"
What Nami saw was a brown furred shortstack with a reindeer appearance of antlers, hooves and a blue nose, and he wears a large pale red/pink fuzzy top hat with a sideways medical cross and a maroon pair of shorts. And the little guy was startled by her sudden movement and tried to hide from her in the open door of the room. The problem is that he did it the wrong way though.
"Ummm... I think you're supposed to do it the other way.", she pointed out.
The humanoid creature realized that she was right and changed his position to a proper hiding position as he originally intended. "A little too late for that now... And I can still see like, half your face. Just what are you?...", she commented.
"S-shut up, you darned human! By the way, how's your fever?", the reindeer boy asked in a nervous and concerned manner at the same time.
Nami replied to him with a grateful nod, "I'm fine, I guess. You were the one who nursed me back to health, right? Thank you."
To her surprise, her apparent savior was trying to act mean but only ending up dancing and smiling in a happy manner in between, "S-shut up! I don't need to hear words of thanks from a human! Don't mess with me, ya hear?! But you're welcome! Glad to be of help!"
"Can't hide your emotions that much, huh?", the Straw Hats navigator dryly commented with a sweatdrop.
Being called out by the human girl on bed, the reindeer boy screamed and ran off from the room as fast as his hooves can take him, "GYAAAAAAAAHHHHHHHHHHHHHHHHHHH!"
"Keep it down there, Chopper!", a voice of a granny called out, revealing herself to be indeed an elder woman with a youthful-looking body and dressed up in clothes as if she had never left her teenage phase and yet she still rocks at it better anyway. "Heeheeheeheehee! Huh, looks your fever has gone completely down, missy. Quite a surprise. You happy, pappy?", she commented as she poked on Nami's forehead while drinking her bottle of booze.
"And you are?", Nami asked while she thought in observation at the older woman's face. She really looks like a witch.
Lifting up her pair of cool shades above her other pair of reading glasses, the elderly but youthful appearing person introduced herself with a confident smile, "I'm Doctor Kureha. But you can call me Doctorine."
"Doctor? Then this is...", the female Straw Hat wondered aloud.
"Do you want to know the secret of my youth?", the Doctorine cheekily asked with a mischievous glint on her eyes.
Nami bluntly interjected with disinterest, "No, I didn't ask."
Shrugging off that her running gag moment didn't seem to work, Kureha answered regardless. "Heeheeheehee! This is the Drum Castle on top of the mountain. Our humble abode as to speak."
"Then there should have been two people with me! My friends! Do you know where they are?!", the orange haired young woman shouted with a worried look of concern for Luffy and Sanji.
Chugging down her bottle of booze, the Doctorine reassured, "Yeah, they're sleeping soundly in the room next door. Chopper is currently tending to their injuries, changing out the used up bandages for fresh ones. Those two are real tough boys."
Nami sighed in relief before she got surprised by Kureha sitting next to her in bed and lifted up her shirt to reveal her stomach. The elderly woman with a youthful body remarked with a raised eyebrow upon analyzing it, "Strange that the bite marks disappeared from your belly. Either the cure must have worked too well or your body's recovery must have been kicked into overdrive... Heeheeheehee! But anyway, this here is the cause of your fever. You were bitten by a Kestia, a poisonous tick that lives on the tropics. Its bacteria causes a high fever, severe infection, myocarditis, and arthritis. Not pleasant."
She added, "Given the infection's progression in the affected area, I guess you'd been infected for about three days now. The pain you've been feeling must have been terrible but still, it would have eased up in two more days without any treatment at all."
Mr. Sariel was right. He did heal my illness away after possessing my body... Although Dr. Kureha cured me at the same time. It might be the reason why she said my body's healing went overdrive..., Nami thought in gratefulness, hoping that the dormant Four Archangels member can hear within her. On the other hand, the host of Sariel hypothetically asked Kureha, "So it would have gone away in two days?"
Nodding, Kureha then bluntly revealed to Nami, "Mm-hmm! You wouldn't be feeling any pain whatsoever because you'd be dead."
Nami paled with her eyes widened and cold sweat forming on her face after hearing that from the witch-faced doctor herself. In hindsight, I think I made the right choice of forming a pact with Sariel..., she internally remarked with relief and gratefulness.
"This particular infection is known as the "Five Day Disease". I had heard that Kestia had died out over a hundred years ago but I kept the anti-biotic just in case.", the Doctorine remarked as she got up from the bed before asking Nami with an amused roll of her eyes. "Where did you guys come from that you may have been exposed to this? Were you walking around some ancient jungle with your belly showing? Heeheeheehee! How ridiculous!"
Remembering how she lost her shirt with only her bra left after Luffy freed her, Vivi and Zoro from Mr. 3's Candelabra that almost turned them into wax statues with fire as a weakness of the Wax-Wax Fruit, and it left her vulnerable to the Kestia bite in the first place, Nami looked away with an embarrassed blush on her face. I'm never living this one down..., she lamented.
Astonished that her joking remark turned out to be true from her patient, Kureha commented with a mild jawdrop, "What? Did I actually hit close to the mark? Well, aren't you a hopeless case?"
Then the Doctorine casually pushed Nami down to bed, stating, "Now, stay in bed for now. The treatment for the disease isn't completely finished yet. Even though you may looked and felt a lot better already, it's still important you need your rest."
"Thank you so much. I'll be fine as long as my fever is gone. My body will take care of itself after that.", the Straw Hat navigator expressed her gratitude to the witch-faced doctor while wondering to herself. On the other hand, I will have to try out either Ark or this Tornado Grace from Mr. Sariel and practice using them. It sucks he had to sleep and didn't give me instructions how to wield them. Although I need to find a way to pass my powers off as a Devil Fruit... But how?...
"Don't go underestimating a normally fatal disease now or depend too much on your body's sudden healing speed, you naive little girl. It'd normally take someone ten whole days to recover with the proper treatment.", Kureha warned before adding with a mischievous smirk. "So unless you feel like experiencing world of pain and dying again, I'd suggest you stay put. Heeheeheehee!"
Suddenly, the Doctorine pinned down a shocked Nami with a scalpel brandished on her left hand and aimed down her patient's throat, "Besides, did you really think you can pass yourself off as a normal human when you're actually a Zoan?"
Eeep! Well, looks like I got my opening but still, she's scary! She really is a witch!, Nami internally panicked with cold sweat on her forehead before gulping. "Am I really that obvious?", she chuckled with a nervous smile even with a scalpel at her face.
Pleased of her patient coming out clean than keep playing pretend, Kureha explained as she removed the scalpel and placed back on her pocket, "Heeheeheehee! Girl, I've met Dalton and he ate the Ox-Ox Fruit, Model: Bison. I fixed him up after he lost his battle with Wapol upon turning against that stupid piece of shit and got thrown in the dungeon with no medical help for his severe injuries unless he apologized to him for his defiance, which he didn't. Like most Zoans, he possessed great recovery rate but against the likes of Wapol in his "ultimate form", he almost died if I hadn't settled in this abandoned castle and Chopper found him with his nose in time for his treatment."*
"Even when you're a Zoan, you were vulnerable to the Kestia bite and it almost killed you.", she added in a scolding manner.
Dalton? Oh yeah, the man who told us about you to go for medical help on top of the mountain. I didn't realize he was a Devil Fruit user just like Luffy... I wonder if Luffy was a Zoan too* like Dalton or probably something else..., Nami internally noted before she said. "... I see. And that's how you found out my body's rapid healing to be that of a... Zoan, right?"
"Indeed, with my advanced medicine, it would have taken 3 more days for you to recover. But instead, it seemed to have accelerated your Zoan's healing factor instead. How fascinating.", Doctorine commented before asking with narrowed eyes, "So, what kind of Zoan-type Devil Fruit did you ate and what animal form do you turn into?"
Just when Nami was about to try think of a name for her so-called Devil Fruit ability and her Zoan form to Kureha, a huge commotion happened with the wooden door barging open wide and the items flying and crashing everywhere in the room. It had left quite a massive mess as an understatement as a result.
"GYAAAAAAAAAAAAAAAAAAAAAA! HEEEEEEEEEELLLLLLLLLLLLLLLPPPPPPPP!", the brown furred reindeer boy named Chopper screamed out loud in fear as he was trying to get away from a hungry duo of Straw Hats, who're holding on to him and wouldn't let go, as fast as he can for his life.
Monkey D. Luffy screamed at him by the ear, "STOP RIGHT THERE, YOU PIECE OF MEAT!"
"Hold your horses, Luffy! I'll make sure to season it up first and turn it into venison!", Sanji told his captain, trying to hold down Chopper.
Saved by Luffy and Sanji! Thank you, guys..., Nami gave a small sigh of relief while noticing that Kureha's attention was turned towards Luffy and Sanji pursuing Chopper. The witch-faced lady remarked on the energy and enthusiasm of the captain and cook of the Straw Hats despite their injuries being covered by fresh layers of bandages that were already showing signs of blood.
On the other hand, the Straw Hats navigator wasn't surprised of Luffy and Sanji being stubborn and they have other priorities than getting some rest and not push themselves too hard that would aggravate their wounds. Not after they went through the trouble of bringing her to Kureha and her reindeer assistant.
Still, I will need to think of a name for a Zoan-type Devil Fruit that Dr. Kureha assumed me to have eaten. Mr. Sariel was obviously not an animal and I am pretty sure that holy light and wind are not animals either..., she internally noted.
"QUIT IT, YOU HUMANS! I HATE HUMANS LIKE YOU!", Chopper angrily protested while trying to break free from their grasp.
Undeterred and determined to make the reindeer boy his meal, Luffy declared, "STOP RUNNING AWAY FROM ME, MEAT!"
"Luffy, I told you not to eat him yet!", Sanji yelled at him, still struggling to keep Chopper down.
"You want to know what he is?", Kureha asked Nami who nodded in confirmation, before revealing, "He's Tony Tony Chopper. Just an average blue-nosed reindeer."
"And I assume he is not an ordinary one?", the orange haired host of Sariel commented.
Suddenly, Chopper's muscles bulged and grew as his body turned tall, large and muscular along with his hooves transforming into hands and feet. It surprised Luffy and Sanji who didn't see that one coming, and then Chopper clobbered them with a double cross punch into the ground. The two Straw Hats collided into the floor, cracking the tiles as a result!
"I AM NOT YOUR FOOD!", Chopper in his transformed state yelled out loud.
"Indeed, he ate the Human-Human Fruit, which granted him human abilities. He's also a Zoan too as well.", the Doctorine confirmed as she watched Chopper returned to his small form and continued running off, looking at him with pride akin to a mother being proud of her son. "I poured in all my medical skill and knowledge in him."
Human-Human Fruit?... Wait, that's it! Sariel was human looking enough and he was one of the Four Archangels if I recall. Not to mention, Kureha said about Dalton's Devil Fruit having a Model: Bison of his Ox-Ox Fruit and Chopper being a Zoan in addition. Time to make good use of this!, Nami found a Eureka moment and capitalize on it.
She called out to the mentor of Chopper who turned her attention back at her with a look of interest, "I see. Uhm, Dr. Kureha, about my Devil Fruit you asked me what it is... I ate the Human-Human Fruit, Model: Archangel."
Author's Note: Okay, the first chapter of "Angels of the Grand Line" is done and I hope you like it. Nami made a pact with Sariel which results in the member of the Four Archangels possessing her body and granting Nami access to his Ark and his Grace, Tornado. On the other hand, Kureha, from her perspective, believed that her patient was a Zoan-class Devil Fruit user due to fact Zoans possessing great strength, power, speed, recovery rate, and every other type of physical boost that one can think of, and was calling Nami out on it.
At least, the comical antics of Luffy and Sanji with Chopper came right in time for Nami to have her brief moment of reprieve and then she took opportunity after Kureha explained to her about Chopper's Human-Human Fruit to give her "Devil Fruit" a name for Sariel's abilities she possessed.
*Regarding the history between Dalton and Kureha, it made sense that the Doctorine had fixed him up of his injuries post-defeat at the hands of Wapol after the Blackbeard Pirates led by Marshall D. Teach had attacked the Drum Kingdom and made Wapol and his followers flee from the country in cowardice. Leaving the vacant castle alone for Kureha to settle in with Chopper where they found Dalton on the brink of death despite his Zoan nature due to his refusal to take back his defiance against Wapol and was refused treatment from the Isshi-20 by the spoiled brat of a king's orders.
*I totally didn't make a reference to the true name of Luffy's Gum-Gum Fruit to be Human-Human Fruit, Model: Nika. No siree, lol.
Enjoy and don't forget to review. :D
