Hyōten Hyakkasō

is a technique of Tōshirō Hitsugaya's Bankai, Daiguren Hyōrinmaru.

Description
As a huge hole opens up in the clouds, a large amount of snow falls down onto Hitsugaya's opponent. When the snow comes into contact with the opponent, ice flowers sprout all over their body, instantly trapping them in a pillar of ice. Hitsugaya claims the life of his opponent will be over when the last of the 100 petals falls.
