Hyōten Hyakkasō

is a technique of Tōshirō Hitsugaya's Bankai, Daiguren Hyorinmaru. It acts as an extension of Hitsugaya's Tensō Jūrin technique, which he rarely uses while his incomplete Bankai is active because he is unsure if he can control who the technique strikes.

Description
As a huge hole opens up in the clouds, a large amount of snow falls down onto his opponent. As 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 when the last of the 100 petals falls, the life of the one who touched it will be over.
