Disclaimer- I don't own Yu-Gi-Oh!

This is my Halloween fanfic for this year! Since Halloween is my favourite holiday (even more so than the Christian holiday of X-mas) i thought i'd write a cute lil' Yu-Gi-Oh fic for it! This fic will include a romance between Seto Kaiba and Katsuya Jounouchi, and there will be ever so mild horror near the end, but nothing really too bad.

A Trick Equals a Treat

Groaning, he swept a hand through his chocolate brown hair, silently questioning the Gods and their ways, I think they need to prioritise more… he sighed heavily, glancing back over to his hyper little brother, who was buzzing around the Halloween isle within the superstore.

"Maybe I should be- nah, wouldn't work… My black hair would be good for… This is stylish, it would look cool… This one's great, but something's not right… Big Brother! What do you think I should dress up as for Halloween this year?" the pre-teen boy spun around nimbly, blinking his large grey eyes, which were filled with such innocence and curiosity.

Seto shrugged casually, "Whatever you feel you would like to be Mokuba," he replied simply and with no emotion in his cold tone of voice.

Mokuba sighed heavily, twisting back around and giving each outfit a final look over when suddenly a soft beeping sound surprised him; pulling out his mobile phone he flipped it open, "Moshi moshi, Mokuba here!" he replied joyfully, "W-what?" his expression rapidly transformed into one of sadness and loss of hope, "Uh, okay, sure… Bye…"

"Problem?" Seto questioned, raising a graceful eyebrow in perplexity.

"That was Touya- he said he can't go Trick 'r' Treating tomorrow because he's been grounded," the tanned boy paused, "He was caught truanting- but now I've got no one to go out with! This is awful! What am-" he cut himself off, smirking darkly and in a very un-Mokuba like way as he turned to look up at his older sibling, a evil glint sparkling in his cloudy eyes, "Brother-dearest, who I love with all my heart and will promise to always get the best birthday presents for, would you-"

"No chance!" the CEO abruptly cut off the other boy, "Mokuba, there is no way on earth you're going to get me going Trick 'r' Treating on the streets on Domino! I'm a business man, the CEO of Kaiba Corp, and I don't have any time for such pointless activities, don't you have any other friends who could go with you?"

"No I don't have anyone else, everyone else is away at parties or at relatives- Seto, you can't abandon me! Halloween is the best holiday of the whole year! I can't miss it! Do you know how that'll make me feel, big brother?" Mokuba begged, deciding on the perfect moment to attack with the 'puppy-dog eyes' effect of his, "I'll be scarred for life! My childhood will be broken!"

"I thought you said Christmas was the best holiday of the whole year? Or wait, you also said Easter, your Birthday and the start of the Summer holidays were also the best holiday of the whole year…" Seto frowned, placing hands on hips disapprovingly.

"Seeeeetooooo! PLEASE!" and attack! Puppy-dog eyes technique! A martial art only mastered by the ultimate geniuses of the begging and trying-to-get-your-way world.

Seto flinched, averting his eyes from the crushing sight before him, why did his little brother always have this effect on him? God dammit, if he didn't get out of this situation soon, something bad was bound to happen!

After a few moments of complete silence, the tension you could cut with a knife, Seto groaned audibly before caving in, "Fine! I'll go Trick 'r' Treating with you then!" once again he questioned the Gods' ways and how it all worked.

"YES!" Mokuba cheered happily, dancing around triumphantly, "So not only do we hafta find a outfit for me, but now we gotta find an outfit for you too big brother!"

Seto sweat dropped heavily, "What have I got myself into…?"
