Seigen Suzunami

was the former Captain of the 5th Division in the Gotei 13. His Lieutenant was Sōsuke Aizen.

Character Outline
Seigen Suzunami can generally be described as a tall man with dark red hair. Coming from a noble family within the Seireitei, Suzunami served as a captain among the Gotei 13 during the timeline of the game in which he appears. Despite his serious appearance, he is shown to have cared very much for his sister as well as his subordinates. This former Fifth Division Captain was created by Tite Kubo for the Nintendo DS game Bleach: The 3rd Phantom and does not appear in the main Bleach timeline, thus he is considered to be a non-canon character. In manga timeline created by Kubo, Shinji Hirako serves as the Squad 5 Captain 100 years before the main Bleach storyline, which may indicate that the game has its own continuity. This is further supported by the fact that in the manga, Kisuke Urahara was only captain of the Twelfth Division while Shinji was captain of the Fifth Division (Urahara and Seigen are both captains during the game's events), both leaving Soul Society at the same time, due to a plot set up by Aizen.

Synopsis
Seigen lived in a mansion with his sister Konoka, and acted as the adoptive father and mentor of Fujimaru Kudo and Matsuri Kudo after he and Kisuke Urahara rescued them from a Hollow. A few years after the rescue of the twins, Arturo Plateado's assault on the Soul Society destroyed the Suzunami house, apparently killing Konoka in the process. After that, Seigen left the Seireitei, believing the Soul Society organized the destruction of the Suzunami house and sided with Aizen. He was later taken by Sōsuke Aizen and transformed into a hollow-like monster, and used as a weapon against the Soul Society. Seigen was eventually killed by Fujimaru and Matsuri, finally died in peace as he was free from his monstrous form.
