Hyōten Hyakkasō

is bankai technique that acts an extension of Hyorinmaru's Tensō Jūrin.

Description
This ability is an extension of Hyorinmaru's Tensō Jūrin power. However, because Hitsugaya dislikes using Tensō Jūrin while his Bankai is active, he rarely uses it. The ability opens up a huge hole in the clouds through which a large amount of snow falls down on to 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 claimed that when the last of the 100 petals falls, the life of the one who touched it will be over.
