Yamada Asaemon Isuzu (山田浅ェ門
Isuzu is a very tall, dark-skinned woman with long, unruly hair. She wears the standard attire of an Asaemon with a dark haori on top and carries two swords strapped to her left hip.
Isuzu is very respectful towards her allies and wishes to avoid any conflict between them. In battle, or when one of her allies steps out of line, such as Kiyomaru, Isuzu behavior changes and becomes more serious and fierce. Isuzu is also capable of self restraint, that is greatly expressed on face, when dealing with a troublesome situation, such as when she tried to hold back her anger and reason with Sagiri as she continued to defend Yuzuriha from her. Isuzu highly respects Shugen and follows his view of justice in believing that criminals should not be given mercy or to those that protect them as well. To this point, she is not willing to cooperate with criminals even if dire circumstances arise. However, she was willing to set aside her morals just once by working together with the criminals of the vanguard to destroy the Banko.
Similar to her brother Genji, Isuzu follows the samurai code of honor known as bushidō. After Gantetsusai brought Fuchi's dead body, Isuzu was prepared to commit seppuku for the death of her fallen Asaemon comrades on the island and hoped that her death would appeased the shogun.
As a child, Isuzu was sensitive about her stature and would often be referred to her as a gorilla. However, after receiving words of encouragement from her brother about gorillas being strong animals, Isuzu no longer took it as an insult and believed that gorillas embody the concept of bushidō.

While traveling to Hōrai, Isuzu breaks down in anguish after the ninja presented her evidence of Genji's death. Having found out more of his comrades have died, Shugen takes drastic measures by using the Dōshi's whistle to summon the Mōnshin from their nest and uses them to quickly transport him and the Asaemon to Hōrai.
After arriving in Hōrai, Isuzu and Kiyomaru follow Shugen as he makes his way forward. Isuzu arrives in the Rentan Temple where she reunites with Yamada Asaemon Sagiri but becomes displeased to see that she has chosen to cooperate with the criminal, Yuzuriha. Though she had her reasons, Isuzu asks that Sagiri join her side as she fights Yuzuriha. Shortly after, Isuzu hears the Iwagakure shinobi signaling that they have captured the Elixir of Life, meaning that the mission is complete. Sagiri begs her to stop from fighting Yuzuriha but is furiously told by Isuzu that once the elixir has been captured the lives of the criminals should be of no concern and sees no other way of settling matters with them.

However, Jikka arrives with the convicts and Iwagakure shinobi to tell her that they need everyone to join forces since it is the only way to take down the Banko and return home. Although she swore on the passing of her late brother that she would not conspire with the criminals, Isuzu gives in to the fact that cooperation is essential and temporarily puts off Shugen's orders.
