The Additional Landing Party (追加上陸組 Tsuika Jōriku-gumi?) refers to the second group formed by the shogun with the initial plan of assisting the first team sent to Kotaku to retrieve the Elixir of Life. However, the group's mission was changed, under Shugen's orders, to eliminating the criminals of the first team, as well as every being on the island, and protect the Yamada Asaemon assigned to the first team.

The Treasure Barge is made up of four Asaemons, three elite shinobi from Iwagakure (previously four before their arrival to Kotaku), and at least fifty Iwa genin. While the Asaemons are the ones given the authority to order the shinobi, the three mainly follow Shugen's lead, making him the official leader.
After becoming impatient with the first team, the shogun decides to form another team with four members of the Yamada clan with assists from Iwagakure. Upon their departure, Yamada Asaemon Kiyomaru tested one of the elite shinobi's loyalty to the Asaemons by ordering him to commit suicide. The shinobi follows through with his orders and reduces the elites down to three.
The teams arrives to Kotaku and encounters the dead body of Yamada Asaemon Eizen, much to Yamada Asaemon Shugen's horror. They are then attack by a Dōshi commanding a group of Mōnshin to attack and capture them. The team manages to kill every single one of the Mōnshin while Shugen defeats the Dōshi and leaves the task of interrogating him to the Iwa shinobi. As they make their way forward, the shinobi discover more evidence that more Yamada Asaemon's have fallen, resulting in Shugen taking drastic measures to make sure they arrive to Hōrai by using the Horse Flute, that was previously used by the Dōshi, to command the Mōnshin to carry the Asaemons while the shinobi follow them on foot.
After arriving at the palace and breached the walls using the Mōnshin, Shugen orders the shinobi to eliminate all criminals and monsters except for the Asaemons. The shinobi confront the criminals and Asaemons but are then approached by an army of Dōshi sent by Rien and engage in battle with both sides. While the four Asaemons make their way forward, the Iwa shinobi captain arrives at the floodgates where Rien is located and orders the shinobi to destroy the ships except for one.
