A/N: I've been dying to write the recent letters as an omake for a while now...
Omake title: Aizen feels it slipping...
"Banzai Banzai Banzai Banzai..." A distant voice continued chanting, like a broken record.
Gin turned around and stared, his eyes wide open, as oppose to his usual squint, 'No... no! Keep that thing away from me!'
"Banzai Banzai Banzai Banzai..." It continued, although it sounded close than before, causing Gin to flip around and sprint down the hallway, forgetting he could even use shunpo due to his fear.
He broke into a cold sweat. Despite the fact he was running away from it, it was still approaching dangerously quickly.
Just as he tilted his head back to look behind him, the thing was in his face.
"BANZAI~!" It's unexpectedly deep voice shouted, as it leaped on top of Gin.
"Get it off!" Gin screamed to no one, wanting to keep far away from Aizen-sama's clone.
He gagged in pain as the thing started jumping on his stomach. "Ow. Ow. Ow. Ow. Ow..."
Aizen heard Gin's desperate shout, and rounded a corner, to see the clone of himself jumping up and down on the poor man as he screamed "Banzai!" at the top of his lungs.
Aizen twitched. 'Can I ever have a peaceful day in Las Noches? It feels like leaving Soul Society was a mistake on my account. However, not even I could predict something so horrifyingly disgusting as watching a naked version of myself jump on one of my subordinates.' He felt like he wanted to just melt away right there and then. He's never going to hear the end of this from the arrancar.
After watching for a few more seconds, he decided to step in. He grabbed the annoying thing's arm, and tugged it away from Gin.
"What're yo thin' yo doin', yo?" It asked, and Aizen finally snapped.
"SZZZZAAAAYYYYEEEELLLLLL!"
Szayelaporro Granz froze, mid-experimemt, and meekly turned his head to the door as he heard Aizen's furious shout. The man wasn't even this angry with Grimmjow...
He gulped, and solemnly awaited the inevitable.
