I have some explaining to do with this one. Basically, I thought, hey, what if Kaiba had a Yami in the way that Marik had a Yami? What if this Yami was somewhat a form of season 0 kaiba looks and personality? And the big quesiton, WHAT WOULD HAPPEN IF THIS WAS A THING? So I wrote this. I hate it.

Warning, a bit gory. Blood and death. So if you don't like that or it triggers you, skip this one.


The clattering sound of metal hitting tile echoed through the mansion, bouncing off the empty walls, leaving absolute silence in its wake.

Kaiba's eyes refocused, set on the wall in front of him. There was blood splattered across its surface.

Stunned, confused, and disoriented, he held his hands up in front of him. Red stained the skin. His hands shook, and he tried to recall the previous minutes for some clue as to why there was blood on his hands. He couldn't remember a thing.

"S-seto…" A small voice came from his feet.

He froze, his breath caught in his throat. Looking down suddenly wasn't an option. The voice was all too familiar, and he didn't want to see what he already suspected would be there.

His arms fell to his sides, and forced himself to turn his head down. Numbness crept over his body, and he dropped to his knees at the sight his brain was trying to reject. The black haired boy, laying in a pool of his own blood, almost motionless.

"Mokuba…" The name fell from his mouth in a whisper. "Mokuba, what happened…?"

Then the pieces started coming together.

The blood on his hands.

The few minutes he couldn't remember.

The knife he'd dropped.

"Oh God, what did I do…?"

The air felt thick.

Mokuba's lips barely moved, his eyes slightly unfocused. "S…se-…"

The brunet reached forward and pulled the boy into his arms. "Mokuba," his voice was louder now, "I don't know… I don't know what happened. Just… Just hold on."

One word came from the boy's mouth. It was almost silent, but Kaiba was just able to make out what he said.

"Don't…"

That one word broke through the numbness, and Kaiba's sight blurred over. "I'm sorry… It wasn't me. I don't remember…"

The boy's violet eyes seemed to focus on Kaiba for just a moment, before glazing over, the light leaving them to be replaced with an empty stare. His chest didn't rise to take another breath.

"Mokuba." Kaiba's voice grew stronger. "Mokuba! Goddammit, no!" His fingers tangled in the boy's hair, and the water in his eyes spilled over. "Mokuba! Don't you dare leave me! Come back, please! MOKUBA!"

The pool of blood on the floor ceased to grow, and the boy's body became cold.

Hidden in the shadows, a pair of golden eyes slipped away into the darkness, satisfied with the scene in front of them.
