Aquaintanceshipping (Hiroto (Tristan) x Espa Roba)
Flaws of the pairing: This… this… God. For starters, I would like to point out the name: "Aquaintanceshipping". How the heck does that even… work? They've never even met in canon. They are not acquaintances, guys!

Anyway. The first thing I thought of: Tristan's quiet attitude and Roba's constant noise ("BEEEM! BEEEEEEEM! BEEEEEEEEEEEEEEEEEEM… GAIZ! I'M PSYCHIC, GAIZ!"). They do not work! And if Tristan can only just tolerate looking after one small boy (a nephew, Joji) during the Death – T arc for one afternoon… How the heck is he going to tolerate Roba's FIVE smaller brothers?
This fic will end with a scream…
Warnings: None – this is another clean one!
Time Period:Just after Joey's duel, Tristan finds Roba crying on his way to see Shizuka (Duke/Otogi is of course watching the whole thing, since he follows Tristan to the hospital in the manga.)
Names:
Esper/Espa Roba = Esper Roba
Hiroto Honda/Tristan Taylor = Tristan Taylor
Duke Devlin/Ryuugi Otogi = Duke Devlin

Okay. Blend into the crowd, keep your head down, match your footsteps to his. Easy does it -
Ah! He's looking around!
I dart behind an old lady with a shopping trolley, then freeze. Tristan looks around, frowning ever so slightly. There's a long pause, then he begins to move once more. I breathe out again, resuming my casual pace.
He hasn't seen me. Good…
What's that?
A strange whimpering; a mewling coming from a nearby side alley. The brunette looks puzzled, and I realize that he's heard exactly the same sound as I. He turns and walks that way, and again I wait before I follow, scaling a ramshackle building with ease, following him with ease from above-
There! A shock of flat green hair, a small figure wrapped into a ball. Tristan sees this person as well, and calls out to it. Immediately, it uncurls, placing both index fingers to its temples. "BEEM! BEEM!" it screeches – much like some demented parrot. It seems to be male, although the bright pink sweater would suggest otherwise.
Tristan blinks stupidly. "Eh?" Inwardly, I groan.
Charismatic as ever.

Down below, the figure looks unamused. "I ESPA-ROBA! PSYCHIC! PSYCHIC! BEEEEEM!" Tristan puts his hands over his ears, and it's all I can do not to burst out into fits of laughter. Roba begins to sob. "But… then…"
I already know how Tristan's going to react – he's the caring one, after all. Sure enough, he goes on one knee to try and help the boy up. "But then what?" he asks, so softly that I can only just hear it.

He shouldn't have gotten so close – the child lets loose with a shriek that could have blown the ears off Chewbacca. (1)"Bad boy… Beat me!"
Tristan inhales sharply, though I can't tell if it's because his eardrums have just been painfully blown apart, or because he's concerned. "Someone beat you… With a stick?"
"No, with his deck!"
Five smaller boys with exactly the same hairstyle and outfits as Roba come creeping out of the shadows of the alleyway. Tristan immediately mutters under his breath, tries to get away, and I watch in interest as the tables are abruptly turned. Roba now seems to be more dominant – he immediately advances, pushing his new advantage. "I live for my brothers…"
The brunette makes a gurgling sound which I doubt qualifies as speech. "Uh… No thanks."
Roba's eyes are reminiscent of a puppy's, and I can see Tristan practically melting under that stare.
"Do you… have a brother?"
The brunette yelps in terror, backs away. "Augh! I mean, no!"
"Would you like to have one?" While Tristan considers the implications of this, Roba begins to mumble once more under his breath: "Beem… Beeem…"
"Wait, what are you say–"
"Let us be brothers! The Force commands it!"
"I don't think so–"
"COME! THE FORRRRRCE! FLOWING!BEEEM!" Roba sticks out one hand. "COME! BROTHER! LET US LIVE TOGETHER!"

And Tristan runs.
Fast.

Notes:
1. Chewbacca – From Star Wars – this isa VERY loud character (basically a brown Yeti) who is known for his howling. Why is there a Star Wars reference in this story? Well, I have no idea. What I do know is that we're still allowed to have it in, since Yu–Gi–Oh came out well after Star Wars did.
