Kuchiki Byakuya

Byakuya has slate gray eyes and long black hair, which he keeps up in intricate white headpieces called kenseikan, which symbolize his nobility as the head of the Kuchiki Clan, wearing one on top of his head and another on the right side.

Byakuya's Bankai, named Senbonzakura Kageyoshi (千本桜景厳 ; literally "Vibrant Scape of a Thousand Cherry Blossoms"), is essentially a much larger version of Senbonzakura's Shikai. To activate it, Byakuya drops his sword. The sword passes through the ground and two rows of giant blades rise up from the ground.

Quiet, smiles almost never, serious, disciplined, elegant, loyal, observant, cold, distant, intelligent, strong, respected.

Byakuya grew in Kuchiki noble clan, joined Seireitei and spent hours training.
He got married to Hisana Kuchiki, the older sister of Rukia Kuchiki. They loved each other truly.
Hisana died cause of an illness, Byakuya adopted Rukia as his own sister.

Byakuya is the 28th head of the noble Kuchiki clan, one of the four great noble families in Soul Society, the Captain of the Gotei q3's six division. As such, he acts in an aristocratic manner — he seems always serene and apathetic towards other people, even when he is actually deeply conflicted.
