Kitty Pryde's father Carmen has run into trouble with the Japanese
yakuza. In order to help him, Kitty follows him on a business trip but is captured by mob boss Shigematsu and the evil ninja
Ogun, who brainwashes her into becoming a deadly ninja assassin. After she has perfected her skills, Ogun orders her to kill Wolverine, Ogun's former student, who has come to Japan to look for Kitty. A masked Kitty almost kills Wolverine, before she is knocked out by Logan's friend
Yukio and comes to her senses. Terrified at having been turned into a killing machine, Kitty wants to flee, but Logan challenges her to overcome her conditioning by focusing on her inner strength. Ogun later returns to attack
Mariko Yashida, Wolverine's love, and his adopted daughter
Amiko in order to draw him and Kitty out. Kitty defies Ogun's renewed attempt to brainwash her, and after Wolverine defeats Ogun, he offers Kitty the chance to kill him, but she balks, stating she cannot do it. For Wolverine, it is the proof that she is truly herself again. When Ogun tries to kill her, Wolverine impales him on his claws. Carmen Pryde exposes Shigematsu's schemes, turning himself in, and they return to the United States. ==Collected editions==
