Yamada Asaemon Shugen (山田浅ェ門
Shugen has chin-length hair with bangs that frame the sides of his face and slight hints of shadow below his eyes. He wears the standard attire of an Asaemon and favors the kataginu over the uniform.
Shugen is very dignified and diligent in his duties as an Asaemon and doesn't take it lightly when other Asaemon don't conduct themselves in the same manner. He has a disdain for criminals and believes that it was pointless to send the assigned criminals to acquire the Elixir of Life. Shugen cares greatly for Eizen and his fellow Asaemon members to the point where he shed a single a tear thinking of their well-being on the island.
Lord Tensen ArcEdit
Shugen sits next to Yamada Asaemon Jikka as he explains to the officials how he managed to return from the island. After angering them, Shugen apologies for Jikka's behavior. They overlook this incident and explains to them the next course of action written in the shogun's message, which is to send out another team of Asaemon to the island. Once they were done discussing matters, Shugen scolds Jikka's behavior but is met with disrespect by the senior Asaemon, causing him to become furious and speaks bluntly that he can not tolerate his attitude. After Jikka apologies, he wonders if there were any more criminals to send. Shugen informs him that the shogun has hired shinobi from Iwagakure instead of criminals and says that he will also be joining the next team as ordered by their leader, Yamada Asaemon Kichiji. He then sheds a tear after realizing that Eizen has failed to report back to him and becomes worried of his other fellow Asaemon members. A worker then comes up to Jikka asking what they should do with the giant monster head he had killed and brought back. Shugen gets close to the monster's head but the worker warns him that it may still be alive. However, Shugen says that the monster was dead after sensing no waves of life force. He then meets up with two additional allies and tells them that the four of them shall make preparations to depart to the island.
After departing the next day, Shugen thinks that Aoki is feeling uncomfortable with the ninjas presence and informs him that he can correct this. Aoki then becomes concerned with Kiyomaru and Isuzu being unranked Asaemon and wonders if they where capable of handling the mission. Shugen tells Aoki that despite not having a ranking they are skilled enough to handle themselves while also including Jikka, saying that he was adequate and declares that they will be determined to help his clansmen on the island. He then watches as one of the ninjas kills himself after being given the order by Kiyomaru to prove his loyalty and is approached by Kiyomaru asking if they can truly trust them. Shugen tells him that he never trust them to begin with and views them no better than criminals. He then expresses his resolve to kill the criminals on the island so that his clan members can return home. However, after being asked if they were already dead, Shugen becomes angry at the thought and tears up hoping that they are safe.
Abilities and PowersEdit
According to Jikka, Shugen is known as the strongest Asaemon in the Yamada Clan. Being the second ranked Asaemon, Shugen's suitability for becoming the next head of the clan rivals that of Eizen. Unlike the first group of Asaemon that were dispatch to the island, Shugen was one of the three that were chosen to join the second team based on pure ability alone.
As an Asaemon, Shugen is capable of decapitating his victims with a single cut of his sword.
