With the others aside as he desired, Raizen was left to face his attackers directly. The apparent leader of this group seemed to believe he was offering his life to them, but this was not at all the case as far as Raizen was concerned. "Comply?" he questioned as the primary male lunged toward him. Raizen's right arm rose casually, resulting in his relaxed hand being in the assassin blade's path. Upon hitting his skin, the blade moved no further, as if Raizen's body were made of a much greater substance than the man's sword. "Iie. You'll all be my test subjects for what I've been working on during my stay here," he said. Suddenly, it seemed as if something within the white-haired man freed itself. His Reiatsu, previously barely even detectable, flared. It quickly reached an intensity equivalent to that of a superior Captain; enough to make even some individuals of Vice-Captain tier buckle and cower. Its presence even seemed to distort space itself within the affected area. Raizen's left hand would then grip the handle of the katana at his left hip, and with a lax hold on it, he began unsheathing its gleaming blade.

"Bankai."

The gleam of his blade became a bright glow which encompassed the entire sword, as well as Raizen himself. "Itsuwatte," he said as this glow became a flash, which faded only to reveal a new form of Raizen's Zanpakutou. The Vice-Captain now wore flowing robes in various layers, along with a cape that seemed to have a mind of its own the way it billowed. Three swords of very different designs were at his left hip, his left hand wielded a staff with a large crescent as its head, and his right hand telekinetically supported an open lexicon larger than Raizen's own torso. "Mugenteki Shintoku." With the release of his newly developed Bankai, Raizen held his lexicon forward. A purple glow emanated from the pages, forming runes which sealed themselves in and imposed an effect on everyone in the vicinity. From that moment forward, any who blatantly sought the slaughter of another would have their murderous intent converted to doubts, as well as visions of their own greatest fears coming to light as a result. These dreams would only intensify until such a time as Raizen deemed it necessary to stop the effect, which he decided would be only after these assailants were driven to literal insanity for aiming their blades at him.
