It is exactly as it should be.
His laboratory hummed with all that he had spent years pouring into it. Read outs glowed their green knowledge, winking coldly the facts which he knew. If he did not, he had but to simply eye them and pluck them up like an old god taking prayers. Monitors blipped late into the night or throughout the day, a steady stream of music that became so entwined with the sound of his heart he kept beating in here somewhere—he often could not tell which was which. The sounds had become one. They had become the things which he placed in his mind at night when he was too weary to make a subject or two scream a little longer.
The smell of it filled his mouth and nose like a lover. Sterile and obsessively clean; the only horror that could grow on his tables were the things he willed into life. Polished steel tipped upward with notched grooves for body fluids and blood gleamed empty and awaiting his next batch of unfortunates.
Everything was exactly as he had always envisioned it to be. At long last he had all that he could have wanted.
He was alone in his lab. There were no subordinates clumsily avoiding him, reeking of stale fear like the experiments that pissed themselves at their death. There were no meek sheep in black and white lowering their eyes, nothing at all to stop him from continuing his work in peace and quiet finally!
He did not understand however, why he could not control his thoughts. Why he could not force them to fixate sternly on the information pouring from one of the strange looking machines he had modified.
After the fifth try, he barred his bone-yellow teeth in a snarl and pushed his hands through the sculpture of his hair, dislodging this morning's careful work with anger. In the black of a monitor before him, the wild of his yellow eyes bored at his reflection. At the black, the white, the purple and the man he was all over.
He listened to the beep of a machine to his right. To another print out being spat coldly into the hum of wires and power. He listened and he heard the sound of nothing threaded through all of it.
Everything was exactly as it should be.
But he did not understand why his reflection stared him back with eyes as hollow as failed experiments. No matter what equation he tried, Mayuri Kurotsuichi could not understand why he began to feel so empty.
