Kaien Shiba (志波 海燕, Shiba Kaien) was the lieutenant of the 13th Division, under Jūshirō Ukitake, up until his death at the hands of a Hollow that also killed his wife, Miyako Shiba. Following his death, Kaien's remains were possesed by Aaroniero Arruruerie who was then subsequently killed by Rukia Kuchiki, sending his soul to Hell in process. During his tenure in Hell, Kaien subdued many of the locals, quelling several rebellions on his own and growing stronger in the process. After many years, Kaien's soul was drawn out of Hell by Jizo Bosatsu after Morgiana Kurokami first initiated her zanpakuto abilities.
AppearanceEditKaien had a youthful appearance and was a fairly tall person, with white skin and aqua green eyes. Kaien had spiky raven black hair. He wore the normal uniform with his lieutenants badge on his left arm as standard. He had a tattoo of the Shiba family crest on his arm.
It is stated that Ichigo Kurosaki closely resembles Kaien in appearance. After first seeing him, Ukitake is stunned by Ichigo's appearance. Byakuya Kuchiki also notes the resemblance and even states that Ichigo's attitude annoyed him as Kaien's had. While Rukia was training Ichigo, she often became exasperated by his lack of understanding of things Kaien would have known.
Kaien's siblings, Ganju and Kūkaku, do not remark upon or even openly notice Ichigo's resemblance to Kaien.
Kaien, a very ethical man, was adored by many of the 13th Division members. He was outspoken and bore a rough disposition, but his down-to-earth attitude was one of the reasons why everyone looked up to him. Kaien treated his fellow company members indiscriminately, regardless of their social standing or rank. Because of this, he was popular among aristocrats and commoners alike within his Division.
Kaien believed that one's "heart" was determined based on the prospects of fighting and protecting. He was a firm believer in Captain Ukitake's policy on fighting, which consists of two types of combat: 1) The fight to protect life, and 2) The fight to protect honor. Kaien took it a step further and believed they both end up being the same thing: "Heart." He believed that every time one connected with another, a little bit of "heart" is born between them. He thought of "heart" as not something inside you, but rather what is born whenever you think of, or remember, someone else. He believed that one's "heart" exists in others, and that it remains with his or her comrades even after death. Having held such views, he believed that people should never die alone.
Kaien's favorite food was ohagi, and he liked to take afternoon naps if he could.
Kaien was the oldest of the Shiba siblings, and grew up in Rukongai, although the Shiba house was once one of the great noble houses. His sister Kūkaku and their younger brother Ganju are all that is left of the Shiba clan. While Kūkaku was old enough to know, Ganju didn't know his brother was a Shinigami.
Ganju's beloved Bonnie-chan was actually an injured piglet in the mountain area in Rukongai found and looked after by Kaien, during the time when the Shiba family was still one of the great five families. Bonnie-chan's ribbon was given to her by Kaien. Bonnie-chan was very fond of Kaien, and even now, she is still not as emotionally attached to Ganju as she was to Kaien. The door guards of the Shiba family - Koganehiko and Shiroganehiko - were previously the educators of both Kaien and Kūkaku. Ever since the demise of the Shiba family, only the two of them continue to serve in the family.
Kaien later decided on becoming a Shinigami; he passed the entrance exam on his first try and was shortly recognized as a prodigy, as he completed the six-year curriculum of the Shinigami Academy after only two years.
Sometime between 110 and 101 years before the current time, Kaien was approached by Captain of the 13th Division Jūshirō Ukitake five years after graduating the Shinigami Academy. During that time, he tries to persuade a then-reluctant Kaien Shiba into becoming his lieutenant. The two converse about the current happenings in Soul Society, including a young Gin Ichimaru who happens to be a child prodigy surpassing the previous record set by Kaien himself. Kaien shrugs off any attempt Jūshirō makes at him being any type of prodigy. While visiting the Shiba residence, Jūshirō is shown to be quite popular with the servants, with Kaien noting that Jūshirō was still very charming and that he had a smile that made his servants blush. Jūshirō dismisses the compliment as he tries to remain humble about his notable quality. After a few years of denying the position, he decides to take it, if not for any other reason than to take care of his family.
Due to Ukitake's sickness, Kaien was usually in charge of everything in his captain's absence. Kaien explaining to Rukia about heart.Added by Renji AbaraiHe was the first person in Seireitei to treat Rukia like an ordinary person since her adoption into the Kuchiki family. Until he came along, she was treated with careful respect to her face and talked about and bashed behind her back. She was grateful for the fact that Kaien treated her as an equal, and it has been hinted that Rukia may have come to develop romantic feelings for him because of this. She didn't pursue him because Kaien was already married to the third seat of the 13th Division, Miyako Shiba.
When Kaien’s wife died at the hands of a Hollow, Metastacia, Kaien swore revenge. Ukitake and Rukia accompanied him in his search. They found the Hollow in its lair, and Kaien asked for permission to fight it alone. Ukitake granted permission, and Rukia watched in horror as the Hollow’s abilities became apparent. Kaien’s Zanpakutō was broken as soon as he touched the Hollow, but Kaien continued to fight it alone. It obviously pained Ukitake to not help his lieutenant, but when Rukia asked why they couldn't help Kaien, he told her that it would kill his pride. Rukia yells at her captain, saying that pride isn’t important compared to life. He answers her calmly: "Rukia, remember this. There are two types of fights. Whenever we are in battle, we must be one of the two. The fight for life or … the fight for pride! Right now … He is fighting for his pride! His wife’s pride … his men’s pride … Most importantly … his own personal pride. Dismiss this as his stubbornness … and let him fight alone like this…" Kaien held his own against the Hollow for several minutes before the Hollow revealed its true ability. It merged itself with Kaien, and when Ukitake stepped in, the Hollow laughed maliciously and told him that he and Kaien were now the same being, because they were both spirits. It was not the same as possession. Ukitake was struck by his illness at that moment, and the Hollow-Kaien attacked Rukia again. Ukitake yelled at her to kill it because it was not Kaien anymore. Rukia stabs Kaien as he leaps at her. Kaien’s consciousness surfaces before he dies and he thanks Ukitake for letting him fight alone. He thanks Rukia, and then apologizes to her.
She takes Kaien’s body back to the Shiba house to entrust him to Kūkaku and Ganju. From that stemmed Ganju’s absolute hatred of all Shinigami. Ukitake went to the Shiba house to explain to Kūkaku what had happened, and she accepted it and decided to forgive Rukia if she ever apologized. It took Rukia many years to work up the courage to do so. Kūkaku and Ganju still make many of their own decisions based on what their brother would have done. That’s why Kūkaku agreed to help Ichigo and Yoruichi. It is also why Ganju eventually came around to helping them.
Since his death, the 13th Division has not assigned another lieutenant, and instead is run by two 3rd Seats, Sentarō Kotsubaki and Kiyone Kotetsu.

- (To Rukia Kuchiki) "Because our captain is weak and sick, I'm usually in charge of everything! Therefore you may call me "Captain" Kaien if you like!"
- (To Rukia Kuchiki) "Remember that as long as you're in my division, I will stand by you even if I die."
- (To Rukia Kuchiki) "Every time you and I connect with each other, a little bit of heart is born between us. Heart isn't something inside you. But whenever you think, whenever you remember someone, that's when heart is born. If you were the only one alive in the whole world, heart wouldn't exist now, would it?"
- (To Rukia Kuchiki) "Whenever you fight from this point on, there is one thing that you must never do. And that is to die alone. Our bodies are composed entirely from Reishi. If we die, our bodies will disintegrate and become part of the reishi that makes up Soul Society. And when that time comes, where will your heart go? Your heart will be passed on to your friends. If you pass it on to your friends, then your heart will always live on within them. Kuchiki, that's why you must never, ever, ever die alone."
- (To Rukia Kuchiki) "I dragged you into this. My stubbornness has caused you pain. I'm sorry. You must be torn apart inside. Thanks to you, my heart can still stay here."
