I don't own Yu Yu Hakusho, Black Lagoon, or Hikaru no Go. It's rated M because it's Black Lagoon, people.

Chapter One: The Trip

It was a sunny day in the city of Tokyo and there was a steady traffic of people about the streets. People were moving to and from their respective jobs whether they were teachers, accountants, teachers, or athletes. One particular individual was coming from a rather unique job in particular. This person in question was a teenager with bangs dyed blonde walking across the sidewalk with an extra bounce in his step.

This person was Shindō Hikaru, and he was a professional Go player.

Hikaru was a rather odd individual not because of his occupation, or because of his hair or the innate talent he had for the game of Go.

He was one-of-a-kind because his interest in the game started because of a thousand-year-old spirit named Fujiwara no Sai. This was a rather long and complicated story, and it was not the focus of why his step had an extra bounce in it today.

The bounce was in fact attributed to the tickets held in his hand that came to his possession by way of the very game he so enjoyed.

:::Flashback:::

Hikaru walked next to Isumi and Waya as they entered the Go Association with their usual eagerness to play the game with their usual passion.

"Hey, what's going on over there?"

Turning their heads at Waya's sudden question, they caught sight of a poster with a crowd of their fellow professionals gathering around it. Curiosity gripping them, they quickly made their way over to the crowd to get a better look at what was written on the poster.

When they finally made their way there, they read the kanji on the paper and stood there for a short while with their mouths open.

This poster was advertising a most unusual competition amongst the Go professionals. It was offering a free vacation for anyone who was to participate in a small tournament that would be hosted tomorrow afternoon.

"Why the hell are they sponsoring something like this?"

Hikaru wasn't exactly complaining, but the managers and title-holders of the Go Association were not known for frivolity and this abrupt little tournament seemed rather out-of-character for them. He wasn't sure at first if it wasn't some sort of prank but the poster looked very authentic in terms of wording as well as the design and the quality of the paper.

"Perhaps they're doing it to encourage more interaction amongst the other pros by offering some incentive to do so?"

Waya and Hikaru turned their heads toward Isumi with expressions of frank disbelief.

Flushing slightly, Isumi went on to elaborate on his statement.

"I've heard that there's been quite an increase in budget for the higher-ups in the association since the Japan-China-Korea tournament, leading to more wide-spread popularity of the game. It could be that this competition is simply a way for them to splurge and reward the pros for their hard work."

Neither of them spoke as eloquent as Isumi was when it came to explaining things but they were able to understand it perfectly.

Hikaru pumped his fist in enthusiasm. "Well, I'm definitely signing up for it. What about you guys?"

Isumi shook his head softly. "I've never been fond of sea cruises, and I'm perfectly able to relax in the comfort of my own home."

Shaking his own head at how Isumi-like that answer was, he turned to see Waya shaking his own head in the negative.

"I'm not fond of the sea myself; besides, Morishita-sensei has been more focused than usual in the study group lately and I want to take advantage of that in order to get even stronger."

Disappointed, Hikaru nevertheless put his game-face on and stated "Well, I'm definitely signing up for this. I've never been on a real vacation before, and I might end up playing some new and exciting pros while I'm at it."

Grinning at his stout statement, Isumi and Waya wished him luck and waited for him while he signed up for the impromptu tournament, and then the trio went back to their normal routine of professional games.

The next day proved to be slightly overwhelming when Hikaru had made his way to the room where the competition would be held. When he entered, he noted with some surprise that there were at least 40 people in groups ready for the informal tournament. Most of the surprise was linked to the fact that he could see none of his friends or any pros he was familiar with in the large gathering.

Then again it did make sense. Ochi and Tōya wouldn't bother with something like this when there was plenty of room for them to play more games and improve on their own time, and the rest of the pros had already dismissed the idea, being uncomfortable at the thought of traveling by sea. To his consternation, he did note that Mashiba was in the crowd as well but he put that thought aside and quickly made his place in the groups.

After everyone had been sorted into their respective brackets, the games began with fervor. Hikaru had been set against a couple of weaker opponents at first, but then the next challengers had given him a hard time.

'Attach here?'

'Yes! I've made life!'

'With komi that adds up to…'

'Need to cut him off right there…'

Much to the shock of the others in the brackets, he had managed to play his way to the final match where he faced off with a 6-Dan and managed, with a surprising comeback and his usual mistakes-turned-advantages, to pull off a victory with a 5 point lead. It took all of his self-control to not jump in excitement in front of everyone when he'd been presented with the tickets for the cruise.

There was another good part about this: he was allowed to bring three others with him on this trip.

:::Flashback End:::

He made his way through the rest of the crowd when his stomach suddenly gave a low growl. Blushing slightly, he turned his head around and caught sight of a sushi bar. It may not be his first choice of food, but he couldn't help but walk faster in order to purchase a snack for himself.

He entered the bar and made his way to the front to place his quick order. The proprietor took a short look at the blond-banged teenager and quickly spoke up.

"We're closing up shop right now, kid. There are no more orders for today."

Taken aback by this frank statement, Hikaru replied with a small bit of anger.

"What?! I wasn't going to order much anyway!"

Unimpressed, the elderly man responded in kind. "We always close up early on the weekends, now buzz off."

Hikaru opened his mouth but was interrupted again by the growling of his stomach. While he blushed in embarrassment, the old man's hard gaze softened slightly and he sighed while reaching for one of his tools.

"You only wanted a small order, right?"

The teen brightened at the sudden generosity and quickly dug into the sushi when it was ready. Mid-way through the food, he was caught again by the mention of the weekend and asked with some confusion "What's the date today?"

The owner responded while putting away Hikaru's payment "The 24th of course."

The significance hit him as he finished up on his meal and left while giving a brief thank-you. When he reached his home, he made a bee-line for the phone and dialed one unused number.

It had struck him suddenly on the way there that his cruise tickets would also be a great way for his cousin to take a well-deserved honeymoon with his new wife.

He listened to the phone ring with a grin on his face which widened when it was answered with a tired male voice answering with "Who the fuck is this?"

"HELLO, YŪSUKE!"

He giggled when a crash came over the line at the sudden noise and was treated to his cousin's infamous temper.

"What the fuck, Hikaru?! Did you call just so you could nearly give me a heart attack?!"

Snickering some more, he replied with "Do you sound so tired because you and Keiko were busy all day doing – "

"Finish that sentence and I will hunt you down and castrate you."

"Fine, fine," he said while waving hand even though his delinquent cousin couldn't see it. "Anyway, I just remembered that I never gave you a wedding present."

"I sure as hell didn't ask for one."

"How would you like a late present right now?"

Three seconds later, "Keep talking," he said with some suspicion.

After Hikaru finished his explanation, there was another pause before a reply came.

"You can really get stuff like that from playing a dirt-old board game?"

Sighing in exasperation, Hikaru retorted "It's not just a board game, it's – "

"Yeah, yeah, I know, I remember the last time you yammered about it."

Sighing once more, he felt an unexpected happiness rush through him. Despite having only a few cousins in his family circle, their own respective paths and lifestyles were so different that they'd never see each other very much and the idea of spending some actual time with family seemed like a good idea.

"So your answer is – "

"Yes, you moron, my answer is yes; Keiko loves the sea so it should be a good honeymoon present."

"Good to know that you can appreciate good genius," he said while imagining the look on Yūsuke's face as he said that.

He felt nervousness creep up on him as he thought about what he was going to suggest.

"Look, about the fourth guest…"

"You want to invite one of your friends? I guess listening to you babble more about Go could help me sleep better."

Hikaru grinded his teeth briefly then made his suggestion with some trepidation in his voice.

"Actually, I was wondering if well, if we could bring Keiichi along for the ride."

He then pulled the phone away from his ear as the inevitable temper of Urameshi Yūsuke blew through the phone's speaker. It wasn't much of a surprise since Keiichi and Yūsuke had never gotten along very well; it was just a part of who they were in terms of personality.

"There's no way in hell you're bringing along that ass-hat on my honeymoon!"

Steeling himself once again, he stood his ground. "Have you talked to Ketsuko-oba-san lately?"

Before his cousin could retort, he continued "She says that Keiichi hasn't taken any time off since Rokuro died."

There was a long pause on the phone line before his hot-headed cousin replied slowly.

"If he pulls off any smartass attitudes I'm shoving him off of the boat, you got that?"

Hikaru grinned triumphantly and said "Great! I'll see you all next week!"

After hanging up, he moved to dial another familiar number and paused with some nervousness and awkwardness seizing his mind. He looked down at the fan he kept in his pocket, gathered up his courage, and slowly dialed the number for his other much older cousin. Listening to the phone ring a couple times, he was answered by the voice of an adult woman.

"Ketsuko-oba-san? It's me, Hikaru."

"No, nothing's wrong, just the usual messes with school and Go."

"Yes, yes, I know, kā-san's already told me to keep focusing on school."

"I actually called to talk to Keiichi; could you put him on, please?"

He waited a little while until his aunt finally managed to call Keiichi down and put him on the line.

"Hey, Keiichi, Hikaru here. Would you be up for a honeymoon cruise?"

:::Roanapur, Thailand:::

"Ah-choo!"

"What the fuck, Rock?! That's the second goddamn time you've sneezed already! If any of us gets sick or any shit like that, we'll all know who to fucking blame!"

Rubbing his nose, Okajima Rokuro looked at the sky briefly, wondering why he suddenly felt a sense of anticipation, and looked back down towards the familiar female frame of his trigger-happy partner.

"It's nothing Revy it's just the usual fresh Roanapur fumes gracing my nose."

"Well quit smelling the fucking roses and help me wipe this shitty brain matter off the car before Dutch has our heads on a platter!"

"You do know those brains wouldn't be there if you hadn't gunned down that rapist who tried to corner you right in the middle of the road next to our car."

"Oh fuck off, you asshole."

Fin

This is slightly AU because I screwed up the timeline. Hikaru no Go's plot ended in the early 2000s while the plot of Black Lagoon takes place in the early or mid-1990s. Yu Yu Hakusho's timeline is unknown. I know getting a cruise through a Go tournament is flimsy but I had to come up with something. Hope you're willing to give this a shot! Please review!
