Chase of Black Sky
Searching for Black Sky, Stick tracked down and attacked the Hand member Aito inside his office in Tokyo. Aito tried to reach his office and grabbed a gun to confront Stick, waiting for him as the elevator's doors opened. Aito shot until running out of bullets, and Stick seized the opportunity to place his katana in Aito's neck as he tried to change the magazine.
Stick asked him about Black Sky's location, and he lied saying he did not know where it was. Aito tried to attack Stick again, but he easily cut Aito's hand making both the hand and the handgun fall to the floor. Stick repeated the question, reminding Aito that he still had three limbs and other appendages left. Aito revealed that the Black Sky was put on a ship headed to New York City, swearing it was the truth upon his own family. Stick coldly told him that his family was better without him, and beheaded Aito with a single blow of his katana, quickly leaving the building.
