…

"Who are they Seto?"

That was the question that started it. Technically that wasn't the first question Mokuba had asked about he and Kaiba's parents, but it was the question to raise more questions.

Mokuba had always been curious about his parents, but he knew how Kaiba didn't like to discuss anything from their past. So, Mokuba would always keep his questions to himself. However, a certain event at school had made him more determined to find out. This event was called 'Parent Career Day'. All the kids from school had brought in a parent, and they would show off on how successful they were or how cool their job was. Mokuba didn't have a parent to bring, and Kaiba was busy with work. Seeing all those kids laughing and bonding with their parents made him feel...lonely. A feeling he thought he would never have to feel again.

"Alright Jimmy," the teacher laughed at the boy and his painter father, "that was quite a show. I'm going to keep this painting for sure."

The teacher smiled as she showed off the portrait Jimmy's father had made for her during his presentation. She gently placed it aside and picked up her clipboard.

"Alright," she called, "next is, Mokuba and his…um, guardian."

"Don't bother," Mokuba sighed, "he couldn't be here today."

The teacher and the other kids and their parents stared at him blankly.

"Again?" she sighed as she shook her head, "you should be grateful that his showing up isn't required for a grade. However, you still need to tell us all about his job."

Mokuba sighed, and noticed the awkward glances from his classmates and the adults. He stood up and walked up to the front board.

"I was orphaned at a very young age, so my brother Seto has taken care of me most of my life."

Suddenly, whispers began to stir about the room. Comments like 'orphan?' and 'poor boy' and 'it must suck not knowing his parents' began to flow throughout the air. Mokuba tried his best to ignore them and continued.

"Currently, he is the chief executive officer of the Kaiba corporation. He oversees all the projects; which are mostly game related. His company makes gaming software."

"Like Sony?" a kid asked from the back.

"Hirito," the teacher scolded, "raise your hand before speaking."

"Yes ma'am," he apologized. Mokuba sighed and continued.

"Yes, like Sony. He not only oversees the projects, but he in fact designed most of them himself. He's currently trying to make a portable virtual-reality set for a home gaming console. That's all I can think of to say."

"Very good Mokuba," the teacher said as she scribbled down something on her clipboard, "alright, next up is Kimi and her mother."

…

Mokuba sighed as he entered the kitchen. He stopped and noticed that his brother was home from work early.

"Oh, hey Seto," Mokuba greeted with a smile.

"Mokuba," Kaiba sighed as he placed his laptop in his suitcase, "I'm sorry I couldn't be there today. Mr. Yudai is a very impatient man and I couldn't reschedule my meeting."

"That's okay," Mokuba sighed, "I just, well, got thinking today...about mom and dad."

"Oh," Kaiba said with a frown, as if he already knew where this was going.

"Well, I know you don't like talking about it," he continued, "but, I need to know. I at least want to know their names. So, who are they Seto?"

Kaiba hesitated. He turned slightly and rubbed the back of his neck. Finally, he sighed, and gave his answer.

"I don't know."

Mokuba frowned. True their parents had been gone for some time, their mother even longer, but Mokuba had hoped that Kaiba would at least have some memory of them.

"Oh," Mokuba sighed, as he looked down at his feet. Then, Mokuba looked up to face his brother, "Is there any way you could find out?"

"Mokuba-" Kaiba began to protest as he turned to face him. He stopped and noticed the look of sorrow etched into his brother's eyes. Mokuba bowed his head slightly; embracing himself for a negative response from his brother. Sick of looking at the disappointment in his face, Kaiba sighed and gave in.

"I can get you their names-that's it. If you want, you can start your search from there; but don't expect me to get involved."

Mokuba smiled and hugged Kaiba.

"Thank you so much!" he cheered.

The boy darted upstairs to put his book bag away. Kaiba sighed deeply and got out his phone.

"Roland, I need you to take me to the county office."

…

Kaiba stepped out of the limo when he reached his destination.

"Leave the engine running," he ordered Roland, "this won't be long."

"Yes sir," Roland said with a bow.

Kaiba walked up several steps and opened the front door. He was surprised to find the place empty. Well, almost empty. An old man with balding hair and thick glasses stood behind a counter organizing files. Kaiba cleared his throat as he approached the counter.

"Oh," the man said as he turned around, "I wasn't expecting anybody this evening. Most of the building is undergoing renovations you know."

Kaiba rolled his eyes and ignored the man's chatter.

"I need you to find me information on Seto and Mokuba from the Kawaisou Village Orphanage."

"Oh," the old man commented, "that place has been closed down from years. Good riddance too. It will be a miracle if I can find any information on that place. Go ahead and sit down."

Kaiba hesitated at first, but then decided that his feet hurt too much too continue standing. He marched across the room and placed his briefcase in his lap. So, he sat there for a minute, then two, then five. After glancing between the clock and his watch, he grumbled and approached the counter.

"Can you hurry it up!" he barked, "I kind of have to be somewhere!"

"I'm hurrying as fast as I can!" the man protested, "the last keeper of this unit did not do his job very well."

Just when he was about to snap back, the man grinned and pulled out a manila folder.

"Here it is!" the man cheered.

The man handed the folder over to him. Kaiba snatched the folder from his hands and looked through it. Aside from a copy of Gozaburo's adoption papers, there wasn't much in the folder. It only took about a second for him to find his and Mokuba's birth certificates. He examined Mokuba's carefully.

"Mother: Nafrini Isamu. Father: Hideki Isamu. Well, that takes care of that."

As Kaiba closed the folder, something fell onto the floor. Kaiba bent down to pick it up. As he paid more attention, he realized that it was his birth certificate. Kaiba merely scanned his eyes across it, but caught something amiss.

"Mother: Nafrini Omari. Father-"

Kaiba's eyes widened; for he realized that the name of his father was not listed.

A/N: I bet ya'll weren't expecting that. Or maybe you were, idk. I re-edited the story (again) because I noticed the brackets I had put in place earlier disappeared, which made things confusing to say the least. Anyways, feel free to comment and tell me what you think.
