Takaoni

is a technique of Shunsui Kyōraku's Zanpakutō, Katen Kyōkotsu.

Description
Katen Kyōkotsu has the ability to turn children's games into a real battle between Kyōraku and his opponent. Both of them are forced to play by the rules laid down within the spiritual boundaries created by the abilities of the Zanpakutō. If you win the game then you get to live but if you lose it, you die.

The rules of Takaoni state that whoever is the highest wins the game and thus gets to live while whoever is the lowest, dies. Kyōraku attempted to use this ability against Coyote Starrk after using Bushōgoma to try and distract him. However, Starrk saw the attack coming and interrupted it with a Cero.
