Seigen wears the standard Shinigami uniform with the 9th Division haori over it. He has dark red hair that is parted down the middle with one stray bang on the left side of his face.
Seigen has shown to be a rather stern man, as he believes in doing his duty as a Shinigami, as well as keeping his personal life separate from his duties (he insists that Matsuri and Fujimaru call him "Captain Suzunami" while they're on duty). Despite being a captain, he is somewhat laid-back, even preferring to be called by his given name instead of being addressed by rank when he is not on duty. Even though he has a serious appearance, he is shown to have cared very much for his sister as well as his subordinates. He also seems to have a desire to be dependable, as he has been frequently doing favors for Konoka throughout his life.
Tomu Kurai brought two injuried twins to him and told him to look after them. When the wounded twins awoke, he and his sister introduced themselves as Fujimaru Kudō and Matsuri Kudō. As they were resting in their household, they fed the two of them some apples. After they ate them, they asked for more because they were hungry. Knowing that only Souls with spiritual potential could feel hunger, they asked the Kudō twins if they would like to become Shinigami. The two were unsure at first, but eventually decided to become Shinigami in order to repay Tomu for saving them and Seigen for looking after them.
Three Months before the start of the series, his Lieutenant betrayed the Soul Society, he battled him and was about to kill his former lieutenant, but Kaname used Bankai, something that Seigen was not prepared for, he lost the battle and vowed to kill Kaname the next time they meet.
Seigen is seen in the Disaplinary Hearing for Roydon Mashūzu. He agrees with Yamamoto to allow Tomu Kurai to punish him. After the meeting Seigen and Tomu where confronted by Amagai, after dismising his claims Amagai left. Later on Seigan asked Tomu to say Hello to his adopted daughter Matsuri Kudō.
