Katen

Katen (花天) is one half of the manifested spirit of Shunsui Kyōraku's Zanpakutō. While under the influence of Muramasa's brainwashing, Katen has a habit of covering her mouth with her sleeve. She is very hostile toward Shunsui, refusing an offer to settle their differences without fighting and calling him arrogant for offering. She always speaks for both herself and Kyōkotsu, who follows her lead, and implies they left Shunsui because of his "dull" personality. She derides Shunsui's practice of being a gentleman in battle, and claims she has no qualms with using full force against him. Initially, Katen and Kyōkotsu are very loyal to Muramasa, holding Shunsui off and refraining from killing him on Muramasa's orders. However, they turn on him once they learn of how he was lying to and using the Zanpakutō spirits to achieve another goal. After being freed from Muramasa's control, Katen is on much better terms with Shunsui, playing a card game with him in their free time and painting on his face when she wins. She is fond of playing the shamisen in her free time, and frequently drinks sake with Shunsui. She is very lazy, refusing to leave a drinking party in order to hunt Tōjū alongside Nanao Ise because she considers it "back-breaking work", and likes to enjoy the finer things in life. She has a sense of aesthetics for beauty, and is irritated when Nanao attempts to throw a party underneath a barren tree. She is somewhat rude toward Nanao, referring to her as "young lady" instead of her real name. However, she is happy when Nanao manages to befriend Kyōkotsu.
