Ryou
Yugi gasped for breath, blood running through his fingers. He could hear a scream in the back of his head, Yami no Yugi trying to help, do anything to save him. But nothing could be done, and Yugi knew this. Blood and air fled his body in spite of his fingers trying to hold them in. His other surged forward, intending to take control. His puzzle glowed, but the glow was dim. Yugi started to cry. By being weak he has killed his Yami, and he knew it to be true. This was a mortal wound.
Sad, tear-filled purple eyes looked up at his attacker. Yami no Bakura looked passively back down at him, still having the nerve to wear his friend's face. Anger started to build. He had no right to look like that. And then something shimmered into existence over Bakura's right shoulder. It was Yami no Bakura, and he wrapped his transparent arms around the solid's waist, resting his chin on the shoulder. Yugi waited for awareness to glimmer in his friend's eyes, for Ryou to wake up and panic, to run for an ambulance. And he waited, and nothing changed. Suspicion leaked into his mind, and Bakura smirked at him, turning his head to whisper into Ryou's ear, then licked it. Ryou smiled, smiled! And then he lifted one of the hands that had been hanging at his side, flicking out his tongue and licking Yugi's blood off. Betrayal ate at his soul, and Yugi cried harder as his life left him.
So died Yugi Mouto, his throat slit by a friend he trusted, and shouldn't have.
