This is the Bankai form of Byakuya Kuchiki's Zanpakutō, Senbonzakura.

This Bankai is basically a much larger version of Senbonzakura's Shikai. To activate it, the user drops his sword straight down. The sword phases into the ground, as though it were a pool of water. Energy ripples expand out, turning the surrounding area dark, and within seconds, two rows of a thousand giant blades rise up from the ground. Those thousand swords scatter, and countless flying blades pierce the enemy.

No one knows the exact number of blades generated, and no one can dodge or even see the movements of these blades. The number of blades is great enough that the user can simultaneously use them for offense and defense. The user can form them into large masses to obliterate opponents instantaneously. As they move through the air like torrents of waves, they give the appearance of cherry blossoms flowing swiftly along the wind.

Senbonzakura Kageyoshi's defensive use allows the user to cover himself entirely in these tiny blades, forming a body shield. Unlike the Shikai, this Bankai is mentally controlled. While the user can control the blades with his mind alone, using his hands allows him to do so more effectively, making the blades increase in speed threefold.

This Bankai has several forms, achieved by arranging the blades in different patterns. Each form presents a different advantage, such as increasing offense at the expense of defense. This variety of techniques makes Senbonzakura Kageyoshi extremely versatile. These techniques are activated by saying the name of the technique, followed by the name of the Bankai, Senbonzakura Kageyoshi.
