A/N: Happy Halloween! I hope everyone has a spooky time on this creeperific holiday! Here's a little Halloween fic with the Kaiba bros; hope you enjoy.
Also, if you haven't already seen it, I did something for good ol' Seto's birthday on Tumblr - my name is stellar-chrondrite on there (yes, I did change it since it became more of an art blog than an ask blog).

Halloween with the Kaibas

October 31st. A day where young kids gathered to go trick-or-treating. A day where competitions for 'best costume' or 'scariest appearance' were in full swing. A day where sweet shops sold their old stock for lower prices because they knew the holiday would attract customers to them.

It was also a day where people remembered the deceased. Those who no longer inhabited the living, breathing world.

Not that Seto cared about that.

To him, Halloween was simply another day where he could help out the orphanage with his outrageous plans that always got the kids excited. There wasn't time to visit the cemetery and reminisce about the past.

That was dead and buried anyway.

Seto pinched the bridge of his nose as he reclined in his leather office chair. His eyes closed and he let out a deep sigh that rolled off the walls in the empty office. The last streams of sunlight tickled the back of the chair and cast a shadow in front of him, stretching out across the desk.

Halloween was always a difficult holiday to prepare for. Mokuba, being the young kid that he was, always insisted that the pair go trick-or-treating - despite Seto's protests that they were getting older and he'd already outgrown the tradition.

Add to this that the brunet's own birthday had only been six days ago, and there were still baby blue streamers scattered across his brother's desk and even in the corner of his own office.

"Maybe I shouldn't bother this year," Seto mumbled to himself.

He thought about it. Halloween was not only a time to get lots of sweets, but also to give respect to those no longer around.

His parents were people to give respect to.

But he wasn't.

Seto opened his eyes and a blaze of anger ignited within them as he thought about the man that had caused him nothing but suffering. The man who he'd thought would give them a better life - only to cruelly lock it away until he had been bested by the one who was thinking of him now.

Gozaburo Kaiba.

He didn't deserve any kind of respect.

The thought of his stepfather made Seto clench his teeth and growl. Oh, how he hated the man! How could he have ever called him 'father' in the first place?! He was downright despicable and dishonest and deceptive and -

"Nii-sama!"

Seto snapped out of his alliterative flashbacks when Mokuba called him. He blinked twice to clear his mind before focusing on his baby brother.

Mokuba was once again ready to go trick-or-treating. This year he'd decided on imitating the Frost and Flame Dragon; he had on a top that was layered over a blue jumper with the left sleeve cut off, and an orange sleeve on his left arm with no top to go with. He had grey trousers and grey trainers on, and he had two masks in his hands - one representing a blue dragon head and the other an orange dragon head. A long 'tail' made from one of Seto's old belts completed the look.

"Are you ready?"

Seto had to press his lips in a thin line to keep himself from laughing. Mokuba looked ridiculous, but it was one of his 'ingenious' homemade costumes and at least he was happy with the outcome.

The raven-haired kid's appearance had certainly cheered up the CEO and those memories of Gozaburo vanished like a fog had lifted.

"Aww," whined Mokuba. "You're still in your work clothes." He pouted.

Seto gave a small smirk. "And what makes you think these are my work clothes?" he asked sarcastically, standing up from his seat.

Mokuba's eyes widened and his smile returned. "Hah ha!" he laughed. "You're the Malefic Monster!"

The elder Kaiba rounded the side of the desk to reveal his evil counterpart's dark blue trench-coat, light blue top and grey trousers and boots. The only aspects that differed were that his locket was still like its usual self and his hair, though messy, was not as long.

"Well, it saves me having to think of an idea, little brother," Seto continued, leaning against his desk. "And it is technically based off of a Blue-Eyes monster, so it seems good enough."

"Alright!" chuckled Mokuba. "Well come on, Seto! We're gonna miss out on all that candy if we don't hurry!"

As the kid rushed out of the office, the holiday spirit returned once more to the CEO. Oh well, would one more year really hurt?

Slipping his hand into a coat pocket, Seto searched for something. He pulled out a pair of fake fangs and tapped them into place within his mouth. Now he truly was ready.

He was going to have some fun with Mokuba. Unwind a little; relax.

He could probably freak that mutt Wheeler out in this 'costume', which would definitely put a proud smirk on his face for the night.

Yeah, that sounded like fun.
