Hanza Nukui

is introduced during The Captain Amagai arc as the leader of the assassination squad under Gyōkaku Kumoi, Ichigo's first Kasumiōji rival, and was the main antagonist during the first half of the Captain Amagai arc.

Appearance
Perhaps Hanza's most notable features are his light purple hair and the scar across his face. He wears a mask that conceals his mouth and nose and red armor over his left shoulder. While using his Bakkoto, which is actually his right arm, the armor extends over his whole body.

Personality
Hanza seemed to be loyal to the Kasumioji, explaining that they need a stronger leader then Rurichiyo to lead them. He also saw Kumoi to be his master and served under him. Being a warrior, he had a strong sense of honor, which led him to attack Ichigo after being defeated. During their fights, he was highly perceptive, matching his opponents strength with his Bakkoto.

History
Hanza was born into a clan that served the Kasumioji diligently. As he put it, they were "the sword" for which to fight the clan's enemies. But in truth, they were highly skilled assassins. Rurichiyo's mother, the former clan leader, died while giving birth and her father passed away due to illness. This left only Rurichiyo to be the heir, but she was still very young. Hanza, realizing that she wasnt strong enough to lead, joined Kumoi and gained a Bakkoto of his own.

Synopsis
After Rurichiyo Kasumiōji came back to her family compound, Gyōkaku Kumoi ordered Hanza to kill her. However, Ichigo and Kenpachi Zaraki were already protecting her. Hanza attempted to scare the former by releasing his Reiatsu, but Ichigo seemed unfazed. In retaliation, Kumoi sent Hanza and a few others to capture the princess in the Human World. Hanza fights Ichigo using a familiar Bakkōtō, and Ichigo thinks he has the upper hand. However, revealing Saiga's second ability, Hanza paralyzes Ichigo. Unfortunately, Yoruichi Shihōin saves him and Hanza is forced to retreat.

Afterwards, he confronts Kumoi and is asked to show true resolve. He does his by merging with Saiga. Hanza then asks Kumoi if he may have three more Bakkoto for his new subordinates, which he found in the criminal underground. Once he assures Kumoi they are capable and skilled, he obliges, but warns the four not to fail. Using the Kasumioji's Senkai Mon, they enter the Human World and split up to fight Ichigo and his friends. Looking for revenge, Hanza chooses to use the new Saiga to fight Ichigo, regardless of what happens to Rurichiyo.

During the battle, Ichigo shatters Saiga's mirror, only to be caught in a mirror dimension. Hanza uses the shards to look into Ichigo's memories and manifest his mother to kill him. His guilt for not saving his mother would have crushed his soul, but he manages to break free and tell his mother he is sorry. With Ichigo now in his hollow form, Hanza feeds more of his Reiatsu into the Bakkoto. His power increases and he is able to contend with the black Getsuga. However, the Bakkoto gains more control, and though Ichigo tries to stop it, Saiga devours him.

Bakkōtō
Hanza primarily wields the Bakkōtō Saiga, which evolves by devouring the spiritual power of its user. Its shape is that of a katana with a large mirror attached at the hilt.


 * Bakkoto Special Ability releasd with the verbal command, Seal him away, Saiga has the ability to momentarily paralyze opponents by reflecting moonlight into their eyes and can create an alternate dimension in which the opponent is left conscious but unable to move. If he channels more reiatsu into the weapon, he can create illusions based on the targets' memories, trapping them until their souls are crushed. At full power, it is able to shoot energy bolts similar to Getsuga Tenshō blasts.
