Chapter 1

Ace was on his way back from successful hunting excursion when he heard it. He had been walking at a leisure pace, all the while carrying a bear five times his size on his shoulder. The scream was loud and full of frustration and horror, one he easily identified to be of Dadan's, his "foster mother". He sighed out loud, aware that there were only two instances in which she would scream like that.

One, she had just heard of him beating other people up or stealing or, basically doing something horrible. Not that he understood why she was so surprised and angry each time she got news of him doing something, appropriately put, bandit-like. He'd grown up with them, their dark and sinful attributes were bound to have influenced him at some point.

The other reason for her scream was, well, the not-so-welcome visit of the most scary, intimidating and crazy man he had the (dis)pleasure of knowing. His so-called loving and caring (Shudder) grandfather. Almost immediately he was assaulted with mental images of the man's affection towards him, which was essentially his oh-so-tender and bruise leaving fist of love. Ace outwardly winced, hoping-no praying to whatever deity was out there that the old geezer was not visiting. He still had haunting nightmares about the last visit. God, he wanted to leave this island so so badly, and his want to be a pirate did not have nearly as much to do with it as his need to get away from the old geezer.

As he heard another scream, he knew that the old geezer was here, for Dadan only screamed so much when he was around. With a tired sigh, he walked to the bandit's cove with resignation all over his face, he was going to get beat up whether he liked it or not. Realizing he would have to face the old geezer sooner or later, he chose to go now. This course of action only stemmed from the fact that the old geezer would track him down later and then his fist of love would hurt even more.

As he walked over to entrance of the cove, he saw the large figures of the old geezer and Dadan. The old geezer was oddly still and calm while Dadan was yelling with her arms flailing about (Which wasn't really beyond her usual reaction to Garp visiting). Magra and Dogra were trying to calm her down, but looked like they might explode themselves. No doubt, they were feeling a ridiculous amount of stress from the mere presence of the eccentric marine.

Ace internally snickered, before quickly sobering up knowing his fate was going to be much, much worse than any of them. He approached, feeling uncertain but making sure he looked confident – well as confident a 10 year old could look. His (not so) good luck made its appearance and suddenly the old geezer was looking at him with a grin so big that it could light up a graveyard.

Ace shuddered, not liking the look of it. His legs wobbled a bit but ace wouldn't let himself run away, not even from the idiotic and senile old man trying to turn him into a marine.

It wasn't long till he was standing in front of the old geezer. Dadan had somewhat calmed down by then and was glaring at the old man so fiercely that if looks could kill, the old man would have been long dead. Although, Ace was more than just a little surprised when the old man, rather than giving him his usual greeting of a fist of love, patted him on the head.

"Ace! How are you?" Questioned the old man with his fucking-grin-that-was-too-bloody-bright

"I'm fine, old geezer" replied Ace, mumbling the last part, hoping he wouldn't hear. Apparently he actually did have some good luck, for either the old man didn't hear him or pretended not to.

"That's a big bear you got there, I see your hunting skills have gotten even better" Said Garp with pride gleaming in his eyes.

Flustered, Ace looked away, unwilling to acknowledge the praise.

"You'll make a fine marine someday!" A tick mark appeared on Ace's forehead and he opened his mouth to give his beloved grandfather a piece of his mind, but his old man seemed to have already made a plan in case of Ace trying to fight to him and effortlessly slammed his fist into Ace's head.

With a yelp, he fell down, clutching his head in pain. Garp laughed heartily

"DON'T TRY TO PICK A FIGHT WITH ME BRAT! YOU'RE A HUNDRED YEARS TOO YOUNG TO BE TRYING THAT"

Standing up, Ace prepared himself for a bout of their usual fierce arguments. He stopped short when he saw his grandfather look at him seriously.

"Ace, I have some good news for you" exclaimed the old geezer and Ace immediately got a sinking feeling in his stomach, especially if Dadan's reaction to this apparent "good news" was anything to go by.

"I brought you a little brother" Suddenly, he brought his arms out of his marines cloak, and while five seconds ago Ace would have sworn up and down that he had nothing in his arms, a tiny bundled figure was presented to him.

Ace was struck speechless and could only stare in astonishment. There lying in the all-too-large arms of the abusive yet affectionate old geezer was a- a- a-BABY!

Eyes wide and mouth wide open in shock, he could only stare. In the background he could vaguely make out Dadan yelling again, something about having had enough of one brat and not having the energy to raise another monster. He could also make out Magra and Dogra , again, trying, and miserably failing, to calm her down.

Swallowing, Ace pulled himself together and turned away from the senile old man and baby with a huff. The baby wasn't actually related to him, that much he knew for certain, so he had no obligation to play the role of the caring and loving older brother.

"His name is Monkey D Luffy" told Garp with a a fond smile.

"So? Why should I care about your real grandson?" Some part of him had to admit that, that had been painful to say. Despite everything, the old geezer was one of the few people in the world he could depend on, no- actually he was the only one he could ever depend on. For all his annoying traits, the man had shown more love and kindness to Ace than anyone ever had in his entire life.

As soon as he said it, he got a taste of the all-mighty and very painful fist of love. He hit the ground with a thud and nursed a very fine bruise on his head.

"EXCUSE ME!? YOU ARE MY GRANDSON JUST AS MUCH AS LITTLE LUFFY IS! I LOVE YOU BOTH EQUALLY! IF I EVER HEAR SOMETHING LIKE THAT OUT OF YOUR MOUTH AGAIN, YOU WILL BE GETTING MORE THEN JUST MY FIST OF LOVE! GOT THAT ACE?"

He made sure that Ace "got" his point with another fist of love. This time, Ace couldn't quite stifle the yelp of pain.

"Okay! Okay! I get it. Stupid old geezer" Ace muttered the last part but alas and woe, luck had decided to go against him this time and his grandfather heard him and delivered his fourth fist of love in the span of a minute.

He would die before admitting it, but he sort-of, kind-of felt warm in a deep, deep minuscule part of his heart. But that feeling was quickly overshadowed by the searing pain in his head.

"AND CALL ME GRANDPA!" Damn old man had far too much strength for his age.

Suddenly, there was whimper from the bundle in the old geezer's arms. Everyone froze, unsure of what was going to happen next. However, Garp was more than prepared and began making ridiculous faces at the baby all the while rocking him. The baby giggled and flailed about.

Ace was surprised when the old man ruffled his hair again. He went to Dadan and gave his usual threat of turning the bandits into jail. Dadan , defeated by the fact that Garp could always blackmail her, tiredly scowled at him and told him to give the baby and leave.

Ace was surprised when tears abruptly welled up in the old geezer's eyes and within seconds he was cuddling the baby to his chest, with…hearts in his eyes?

What. The. Hell.

Ace blinked and watched in utter stupefaction as, God there were actually hearts flying around the old man. Ace rubbed his eyes, praying for it to be a dream. Great, he was already having nightmares about an old grandpa with a knack for punching people whenever he wants to. And now they were going to involve hearts flying around him. Jut great.

(Shudder)

Before he knew it, the old man was saying goodbye (another fist of love) and was gone, having left with the promise of training him on the double during his next visit.

Ace sincerely hoped that his visit would be after a loooooong time.
