In some anonymous island at the Calm Belt we find Luffy with his little sister Mai and his mother to spend a usual and quiet day as they just finished their training. As usual after the training the three of them go for a treat as a reward for the good job.
"Luffy-niisan is very stronggg!" Mai said with a big grin as she throw herself at her bother while Luffy take her piggyback and carry her making him blush and their mother to smile at her daughter's antics with a sweet smile.
"Can you please stop saying such embarrassing things?" Luffy said to his little sister frowning.
The three of them continue to walk until they reach the center of the island where all the stores are, as their mother has promised they enter in a shop and they take three ice-creams before they leave to return back to their home.
After some minutes they reach their home and Luffy go for a shower as he was dirty and sweat from the training, the house isn't huge but still it's enough big and warm with moments of laugh, joy and love.
After some minutes Luffy has finished his bath and after he get dressed he go to find his mother and his little sister, but to his surprise he find also his grandpa who has long time to see.
"Hey gramps! Nice to see you again." Luffy say to him with a big grin on this face.
"How is my two grandchildren?' Garp asked as he run and hug both Luffy and Mai making Luffy to protest and Mai to shout from joy.
"Come on Garp, the food is ready." Rose said to him as Garp put down the kids and run to the table drooling.
Rose and Luffy serve the food as Garp start to protest that his portion is to small making Mai and Luffy to laugh while Rose shake her head irritate from old man idiocy.
The lunch was noisy as always when Garp decide to pay a visit to see his grandchild and Rose as his son is rarely here.
"So, how is my son doing?" Garp ask Rose now that they're alone since the kid go for a nap.
"Garp, please don't start again." Rose say to him smirking.
"Come on Rose, don't tell me that it doesn't bother you. He is an admiral for god's sake and you were the best assassin in history." Garp say to her sighing.
"Yes I was, and you point is?" Rose ask him.
"My point Rose is that even my idiotic son can't be so fool to see that the world is corrupt as hell even if he is a marine, I also fear that sooner or later they'll find who are you and they will come after you and my grandkids." Garp say to her as Rose eyes start to burn like inferno.
"I know that Garp, but don't fool yourself if someone dare to touch even a hair of my kids I'll gut him. I may gave up my old life when I had Luffy and Mai but I didn't forgot how to fight, the person that will dare so much to threaten my kids will sign his death sentence." Rose say to him as Garp look at her and nod his head.
"Rose…?" Garp ask her, "Yes Garp?" Rose say as he look at him.
"I don't say that I don't believe you nor that you'll not protect your kids, only a fool will believed that. But let me ask you something and don't take it wrong." Garp say to her as she nod him to continue.
Garp sigh and look at her in the eyes.
"How long do you have to wield a sword?" Garp ask her as Rose raise an eyebrow.
"I'll train everyday Luffy for two years already." Rose answer him. "Let me rephrase it then, how long do you have to fight against a serious opponent?" Garp ask her as Rose het the meaning.
"Too long." Rose simply say to him as Garp nod his head.
"You afraid that my skills are start to rust and that I start to lose the killing instinct." Rose say to him but Garp didn't say anything and remain silent although Rose understand very well that he didn't need to say anything. She know him very well now.
"Garp." Rose say to him with gentle voice as the old man look at her and nod.
"If something happens to me I want to take the kids to Amazon Lily, the previous empress owns me a favor and also this place is pretty much protected and isolate." Rose say to him as Garp's eyes widen.
"I know the island I saved three girls from there not too long ago, but Rose what about Luffy? Do you believe that he'll be welcome there?" Garp ask her.
"I really don't know Garp…I mean Luffy may seems the happy go lucky kid especially around Mai but there are times when I catch a shadow in his eyes… He is the person that will close his feelings into a bottle for the sake of the others. I know that Mai will have Luffy to ease her pain and also her age will help…but Luffy is entirely another story." Rose say to him with a solemn look as Garp nod his head and stand beside her.
"What is that you fear?" Garp ask her.
Rose sigh and look at the direction that is the kid's room.
"I fear that if something happens to me that Luffy will not be the same anymore, I fear that my only son maybe don't smile ever again. I fear that if something happens to me it will ruin his life." Rose said as a single tears drop down to her cheek.
"You know better that anyone that Mai is more than her father while Luffy have my character, he can suffer and bleed inside but he will smile and laugh it off for the sake of his little sister or mine." Rose continue to say as Garp nod his head and put a hand on Rose shoulder.
Of course Garp know this, his grandson wants to look strong and he'll protect everyone with his life even if he slowly dies inside him from the pain. He'll laugh and joke like a madman to make everyone smile even if inwardly want nothing more to cry and curse. He'll hug everyone, shield them from the any pain and tell them that all is at the past even if he wants nothing more than to go and butcher everyone…And he'll do it, he will do exactly that when nobody is there to see him. He may wait for a day, a month, a year…hell even ten years but in the end he will have his revenge. He always have his revenge exactly as his mother because… she haven't named by accident Bloody Rose.
"Let's go to take Mai's birthday cake Rose before this little monsters start to wake up." Garp say to her with a gentle smile as she smile and nod her head and leave the house.
After some minutes they're back and Rose put the cake in the fridge while the kids start to wake up, as always Luffy has piggyback Mai as for some reason she finds it cute to make Luffy embarrassment and besides she knows very well that her big brother may protest and frown but he will do everything for her at the end of the day.
Both Rose and Garp smile at the image but inwardly they still remember their previous talk and the image that just saw proves exactly both Rose said and Garp knows very well.
After Mai is satisfied she just step down from Luffy's back, kiss her big brother at the cheek while asks from her mother a snack leaving the little boy to blush and more oblivious than ever about what just happen while Garp start to laugh thinking 'poor…poor boy.'
Luffy start walk towards Garp smiling but for some reason Garp start felling a chill run towards his spine, he sit beside his grandpa while the old man look at the young boy trying to read him.
"For the sake of my sister I'll not say anything but, if something happens to my mother while you're here and you don't save her I'll never forgive you." Luffy say to him while he look at the kitchen where his little sister and his mother is and still smiling.
Garp from the other hand look at the little boy with widen eyes knowing very well that he utterly means what he just said to him, the only question that remains is how the boy was able to hear what not long ago both him and Rose has said. But before he can ask Luffy stand up and walks towards the kitchen but before he enter he stops and look back at his grandfather with a look that Garp has never see before…or not? No he has not seen before that look in Luffy's eyes but he has saw it many times at the past in Luffy's mother.
Yes he has seen that inferno many times in Rose's eyes when she was more than pissed…but never to that level and never in a small child. An inferno that can burn hotter than the hell himself, than can incinerate not just an enemy but the whole world if someone dare to challenge that person. And at this very moment Garp start to realize that both Rose and himself they're greatly underestimate that boy, Luffy can be a very dangerous man if something bad happen and lose himself in it.
Luffy continue to walk as he finally enters the kitchen with a big grin on his face as nothing ever happen and look at his two true treasures, his loving mother and his adorable innocent little sister. Because yes this two are his true treasures whatever the world may think or say!
"Luffy-niisan I kept that for you!" Mai said as she run towards him with her plate and give to him her half sandwich making Luffy to look at her with widen eyes.
"You don't want it Mai?" Luffy ask her as she shake her head. "No I keep that for my strong niisan." Mai say to him as Luffy is now redder than a tomato.
"What's the matter with all niisan thing?" Luffy ask her annoyed but not really as Mai don't bother to answer him at all and struck out her tongue making Luffy to murmur various things while Rose start giggle to their antics with a soft and sweet tone.
They four of them spend the noon as usual, Rose has taken Luffy for training while now that Garp is here he stayed with Mai to play. For his bad luck Mai decide to have a tea party and the poor Garp didn't have another choice that to comply. The old man start really feel what his poor grandson have to endure every day and he didn't want to be at his seat at all.
(With Luffy and Rose)
Luffy despite that he only practice swordsman for only two years he have a natural talent for it and Rose can't be any happy and proud than already is. He was able to learn countless techniques as also her two personal favorites, but not only that he start to invent his own technique taking pieces of those two styles and combined them making an entirely whole new technique that is more deadly that any of them.
After two hours they finish their practice and they decide to return home to see in what condition the poor Garp is.
Luffy start suddenly to laugh as Rose look at him with a raised eyebrow.
"What is it Luffy?" Rose ask him with a gentle smile as he look at her.
"Sorry it's nothing, I'm just happy…shishishi…that someone else…shishishi…will have to endure a broken pride…" He said as he burst into a laugh not able to hold it anymore while Rose start to laugh too knowing very well what her son means.
After some minutes they reach the house and indeed what they see make them to fall and roll at the floor laughing. At the center of the room was Mai with her new victim (jiiichan) and they have a tea party, (as*cough*the once feared*cough* by many *cough Monkey. D. Garp cough cough*) while the poor man have a variety of jewels, make up and a bright red lipstick and at his face a look of terror.
Yes the all mighty Monkey. D. Garp has been utterly defeated and his pride has severe damaged by his four years old granddaughter.
Luffy walk towards his sister and pat her on the head.
"Come on Mai lets go to the playground and I'll swing you if you want." Luffy say her as Mai didn't need to think it twice, she hugs her brother as Luffy smile and nod his head to his gramps as if saying you own me one and take his sister and leave.
"Something tells me that I'll pay dearly that favor." Garp says as he sigh while Rose put an arm to his shoulder and smile to him.
"He could easily take a picture of you in this state but instead he choose to free you, what of those two you prefer?" Rose ask him with a mischievous smile making Garp to gasp and widen his eyes.
"I'll take the second option every day-any day." Garp say to her as she nod her head and smile.
After an hour or so the two kids has return with Mai pouting and Luffy clearly in a very bad mood, something that didn't go unnoticed by the Rose and Garp.
"Come on niisan, please talk to me" Mai say to her brother pout even more.
"Mai, please I'm not in a mood right now. Go play with Gramps or Ma" Luffy say to her not looking her at all.
"Luffy-niisan is hating meeee" Mai said as she start to whimper making Luffy to panic.
"Wha…Whatttt? I don't hate you moron. You're my cute little adorable sister." Luffy say to her as Mai stops and tackle him to the ground while she hug him embarrassing him once more again.
"Yeah my niisan loves me!" Mai shout as she throw her fists at the air while once again Luffy blush and murmur various curse.
"Alright, what is was this time?" Rose say and look at Luffy.
"Why you look at me?" Luffy protest with shark tooth making everyone to laugh.
"Because I know my son?" Rose ask him as she raise an eyebrow making Luffy to sigh.
"Some stupid kid pushed Mai while we wait on the line for the swing and she fell down." Luffy say to her as she and Garp start to sweat drop.
"And, he's still with us?" Garp ask him fearfully making Luffy to look at him with narrowed eyes.
"Of course his still with us…" He said as both Rose and Garp sigh relieved. "I just beat him to a bloody pulp, that will teach him some manners next time." Luffy continue to say as they start to sweat drop again.
"You know that you have a sis con…" Garp said laughing but the moment the words left his mouth the temperature in the room feel like drop ten degrees.
"Say that, One. More. Time!" Luffy said as a dark and menacing aura start to emit from him making Garp to gulp and cowering in fear shaking his hands innocently.
"I thought so." Luffy say to him as the aura disappear while Mai look at him with stars in her eyes making everyone to laugh and the little girl to pout.
After some minutes the dinner was ready and this try Garp try to behave himself…the key word is try. Although he wasn't the usually loud and disgusting Garp as always he still have absolutely no table manners of how a person can eat politely without throwing the food all over the place.
Rose and Luffy just sigh while Mai as always find it cool how a person stomach can be a completely bottomless like a black hole. Nope there is no help, Garp is utterly hopeless in that subject and Luffy start to pray to whatever god is upon there that his little sister didn't heritage olds man manners because then he'll sure have a heart attack.
The dinner has finish after some hours and it is time for sleep for the two young ones. Mai is already sleeping as Luffy take her at his arms and put her on the bed to sleep as he good night everyone while Rose came after a while to give them a good night kiss.
"Tomorrow is a big day. It's Mai's birthday and I'll be damn if I don't make her to enjoy that day.!" Luffy start to thinking with a fire determination and a soft smile on his face. After all he only has one sister and she means the world to him.
A/N: Alright guys, this was the first chapter so tell me your opinion.
