What does Tōshirō Hitsugaya say when releasing bankai?

Answer 1

Hyōrinmaru's bankai, named Daiguren Hyōrinmaru (大紅蓮氷輪丸, literally "great crimson lotus ice ring"), causes ice to flow from Hyōrinmaru onto Hitsugaya, forming into two large wings, a tail, and twelve large flower petals. Hyōrinmaru's bankai has four known special techniques.

# The first is Ryūsenka (竜霰花, literally "dragon hail flower"), which freezes any enemy Hitsugaya stabs, locking them into a cocoon of ice and freezing them to the core. Once frozen, Hitsugaya can shatter his opponent. # The second is Sennen Hyōrō (千年氷牢, literally "thousand-year ice prison"), which forms a multitude of ice pillars using the moisture in the atmosphere. These pillars hold the enemy prisoner for a thousand years, also freezing them. # His third technique, Guncho Tsurara (literally "icicle flock"), he launches a multitude of ice shards in an attempt to impale his opponent. # His fourth, and implied most powerful move is called Hyoten Hyakkaso (literally "frozen sky-hundred flowers funeral"). This attack causes 100 snow flakes to fall from the sky, freezing anything they touch in a flower like shape. When all 100 flakes fall, the life of the one trapped by the attack is over. So, he says Daiguren Hyōrinmaru when releasing bankai.
