Nidanme: Zanki no Shitone

is a technique of Shunsui Kyōraku's Bankai, Katen Kyōkotsu: Karamatsu Shinjū.

Description
Black spots appear all over the body of Shunsui's opponent in a manner similar to a disease, causing them to bleed profusely.

Shunsui poetically describes this technique as "The man, regretting the wounds he inflicted upon his partner, lies face-down in bed with a deep sense of shame and is stricken with an incurable disease."
