Makai appears in Suikoden II.
During the Dunan Unification War, Riou went to Two River to forge an alliance, but was rejected by Makai. When Kiba Windamier went to Two River, he offered a truce. Makai accepted the truce without seeing Kiba's true intention. General Ridley, the chief of the Kobolds, when he heard about that, thinked he was betrayed by the human side. The truce was only a trick by Klaus Windamier to cause damage to the friendly relation between Kobolds and Humans at the Two River.
When Kiba attacked Two River, Makai and his forces had to fight them without the help of the Kobold Warrior. Luckily, Chaco a Winged Horde, helped and led the wingers to attack the Highland Army. Soon the Kobold Army joined in and fighted along side with them and Kiba had no other choice but to pull out its troops. After the event in Two River, Makai forged an alliance with the New State Army. After the war, Makai continued as plenipotentiary for Two River.
