when did this fight happen? which episode??
She became friends with the division lieutenant, Kaien Shiba and greatly admired his wife, 3rd Seat Miyako Shiba. When Miyako was killed by a hollow; Rukia, Kaien, and the division's captain, Jūshirō Ukitake hunted the hollow down. Kaien faced the hollow alone but the hollow's special ability destroyed his zanpakutō. Rukia attempted to draw her sword and help but was stopped by Ukitake. He told her that Kaien's fight was one of honor rather than a fight for his life. If Rukia helped, Kaien would be saved but his honor would be damaged forever. Meanwhile, the hollow entered Kaien and possessed him. Ukitake faced the hollow but his illness allowed the hollow the opportunity to attack Rukia. Kaien momentarily regained control and thrust himself through Rukia's zanpakutō. He thanked Rukia and Ukitake for letting him fight for his honor and died in Rukia's arms. Rukia brought the corpse to the Shiba family but was afraid to apologize since she felt guilty about her role in Kaien's death. help!..i want to watch.
Kisuke Urahara gave her a special gigai body when she gave her shinigami powers to Ichigo. This body is special in that instead of healing the users so he can regain his powers, it decreases their energy until they have no spirit power left, thus turning Rukia into a regular human.
