After the shogun called for criminals to acquire the Elixir of Life from the dangerous island known as Kotaku, in exchange for a pardon for their past crimes, Kishō joined in the expedition team as one of the Yamada Asaemon monitors and was assigned to keep watch over the criminal, Warped Keiun.
Kishō had short hair with his face framed with bangs. He wore a dark haori with the standard attire of a Asaemon underneath, which is a white robe with a bell tied on the left collar along with a hakama held together with a waist cord, and sandals.
Kishō was an individual who was known for never losing his composure and rarely acting assertive. He was able to see the big picture in situations and found it annoying when people questioned his way of handling them. Kishō had shown that he didn't mind in taking the easy way out, offering to cut down Gabimaru to help Sagiri return home instead of following through with the mission. He also doesn't like to be pushed around. After being set straight by Gabimaru, Kishō smiled saying that his time with finding the elixir will run out and the shogun had plans to have people from Iwagakure involve, which had Gabimaru concern.
Kishō was one of the few Asaemons who got assigned to a criminal and sent to search for the Elixir of Life on an island as ordered by the shogun.
Upon arriving on the island, his assigned criminal, Warped Keiun, encountered and attacked Gabimaru in an attempt to lower the competition. Sagiri was surprised that Keiun's arms were not bound and asked Kishō the reason behind this. Kishō tells Sagiri that he would simply redo his bindings when it was time to return home and that no one is following the rules. Keiun attempted to kill Gabimaru but is met with death by the shinobi. Kishō drew his sword and cuts off Keiun's head. With his criminal dead, Kishō prepares to head back home. Before leaving, Kishō warns Sagiri that the criminals have plans of their own to find the elixir and that the rules don't matter on the mission. He also offered to kill Gabimaru in order for her to return home. Having heard enough talk from him, Gabimaru grabbed his sword and silenced him. Kishō then told Gabimaru that his time with finding the elixir will eventually run out and Iwagakure might be involved. He also tells Sagiri that the mission will determine the next head of the Yamada clan and makes his departure.
At some point, upon his departure, Kishō somehow became infected with Arborification and immediately died. After trying to make an attempt at escaping the island, Nurugai & Tensa finds Kishō's bloomed corpse. As Tensa tries to get a response from Kishō, the dead Asaemon is split in half by the Watatsumi's large tentacle.
