Author's note: I do not own Bleach or its characters. This is AU. I am not very familiar with the Bleach anime, and Katen Kyokotsu's personality is based on the manga and my own suppositions.
Darkness
Katen Kyokotsu was extremely unhappy. Separated from his partner and swathed in silk, the sword spirit was effectively blind, deaf, and dumb. All of the sense he had were blocked by the silk and the lack of his shinigami partner. He wasn't entirely sure how they had managed to get him away from Shunsui. His partner tended to guard the two swords that the spirit inhabited as closely as he guarded his sake. For someone to actually get a hold of the swords did not bode well for either of them. But there was nothing Katen could do as he was. He was trapped for now, and there was nothing he could do. It was not a good situation for anyone.
Not when he and Shunsui were responsible for protecting the inhabitants of Kyoto from the dangers of the supernatural world. Most of the enemies that would try and separate the two of them would have destroyed Katen Kyokotsu as soon as possible. The fact that there hadn't even been an attempt to destroy him yet bother Katen. He couldn't think of many reasons why they wouldn't have destroyed them, and none of them were good. But until someone unwrapped him, there was nothing he could do.
