Ban-Kai: -- Senbonzakura Kageyoshi (One Thousand Cherry Blossoms Brutal Shadows) Byakuya releases his zanpakutou and one thousand swords apear all around him. They rise from the ground then those thousand swords scatter and countless flying blades peirce through the enemy. No one knows the exact number of blades generated. No one can see the movements of those blades or dodge them, except Kurosaki Ichigo. Byakuya's Ban-kai's final stage is called Hakutieken (White Imperial Blade)
Kuchiki Byakuya first arrived in Bleach as the silent yet powerful Shinigami sent to Kuraku town alongside Renji to find and bring Rukia back to Soul-Society. His power is immediately made evident when he steps in to aid Renji in his fight with Ichigo ending things in a matter of seconds leaving Ichigo bladeless and lying face down on the ground with what he thought was little hope for survival; and this proves to be only the beginning of his power. Descending from the Kuchiki clan one of the four noble houses of soul society captain of the 6th division Kuchiki Byakuya is also Rukias older brother though they are not related by blood rather, Rukia was adopted in to the Kuchiki family. Because of his noble roots and his superior level of power Byakuya tends to carry himself with a level of arrogance and an I’m-better-than you attitude, this is clearly seen by the quite rude and often times sarcastic manner in which he talks to most people around him.
Byakuya is also a shining example of what a shingami should be as he is extremely law-abiding, this devotion to the law is also heightened by the fact that he is a descendant of a noble family to Byakuya it is the responsibility of the Nobles to lead by example if they do not obey the rules of Soul Society then who will. Byakuya is a nobleman to the core and appears to be unflinching in his devotion to his duty even after Rukia has been sentenced to execution. In his mind regardless of whatever conflicts he may have been feeling on the inside his duty as nobleman and a shingami was to uphold the law and word of the 46 chambers; no feelings he may have would be allowed get in the way of his duty as a result of this his outer shell never cracks or shows anything other than his typically cold exterior.
There have only been two occasions when Byakuya stepped out of the bounds of his Noble responsibilities, firstly when he married his wife Hisana and secondly when he adopted Rukia into the Kuchiki family. His marriage to Hisana was looked down upon as she was not of noble descent and in the Kuchiki family the mixing of blood between somebody of a noble house and someone from Rukongai was forbidden, for this same reason it was also frowned upon when Byakuya adopted Rukia into the Kuchiki family. Rukia was the sister of Byakuyas late wife Hisana whom abandoned Rukia when they lived in Rukongai as the responsibility of raising her was too much, this decision was one that Hisana always regretted and on her death bed she asked Byakuya to find her sister and use his power to protect her. He did this by adopting Rukia into the Kuchiki family at which point he swore to himself on his parent’s grave that he would never again break any laws or overstep the bounds of Nobility.
Byakuya's Zanpkauto's name is Senbon Zakura (thousand cherry blossoms) in its unreleased form looks just like an ordinary Katana. To release his shikai Byakuya uses the simple phrase Shire·(scatter) at which point the blade of his zanpakuto seems to disappear, in actuality the blade has scattered into one thousand blades so small they can only be seen when they reflect the light and appear to twinkle in a manner extremely similar to scattered and falling cherry petals. His Bankai Senbon Zakura Kageyoshi is fundamentally the same as his shikai just with an increased level of power, after dropping his blade into the ground two rows of swords rise out of the ground next to Byakuya at which point the blades scatter again, however, in his bankai attack the sheer volume of the blades and speed of the attack mean that most people cannot even see it coming never mind actually dodging it.
Byakuya's bankai also has a final stage Hakuteiken or white imperial blade where he gathers all the scattered blades of Senbon Zakura Kageyoshi and reforms them into a single white blade.But al last, he fall to Ichigo after the horrible fight with Hollow Ichigo. Byakuya later risked his life to protect Rukia when Gin striked her. Somehow, he survived and continued his life.
