A hundred years ago, Kaiser was the protector of Pantheon and defended Grandis from Magnus, one of Gerald Darmoor's and the Black Mage's Commanders. Kaiser proved to be no match for Magnus and his forces, due to having been previously poisoned by Magnus, prompting Kaiser to sacrifice himself. In present day, a young Nova boy named Kyle is revealed to be the next host of Kaiser's legendary powers.
A hundred years ago, Kaiser was a defender of Grandis. Kaiser tells his comrades Cartalion and Fenelle to stay behind and protect Pantheon while Kaiser went off to fight against the Nova's enemies. Magnus reveals to have betrayed his race in exchange for power, then poisons Kaiser and summons endless waves of Specters. Kaiser then transforms in his final stand, but Magnus still proves too strong. With no other option, Kaiser unleashes an attack that eradicates Magnus' forces but also himself in the process. Meanwhile, Beldar, a high priest of Heliseum, informs Cartalion and Fenelle that Magnus has taken over Heliseum. They discuss that Kaiser will eventually reincarnate into a Nova child but kept this a secret, lest their enemies target the Nova children.
In present day, Kyle and his friends Tear and Velderoth formed the Heliseum Force, claiming to be defenders of Pantheon. Kyle then senses something amiss and discovers nefarious priests attempting to seize a relic that energizes the shield around Grandis. Velderoth leaves to get help while Kyle and Tear attempt to stop them, but Tear is quickly defeated. Kyle kills one of the priests and the powers of Kaiser awaken within and then slays the remainder of the priests.
Kyle awakens in a nursery room where Cartalion and Fenelle reveals that he is the reincarnation of Kaiser, and that he must accept his destiny as the defender of Pantheon.
For the second, third, and fourth job advancements, simply reach level 30, 60, and 100, respectively, then accept Kaiser's quest to advance.
- Kaiser is the third class who is not a human, the first being Mercedes, followed by Demon, and is preceded by Angelic Buster and Zero.
- The former Kaiser's weapon is named Kaisereum. The naming is likely a portmanteau of Kaiser and Heliseum.
- Kaiser's name translates to Emperor in German.
- In JMS, CMS, GMS, and EMS, rather than having one set of swords for the Tempest Blades skill, they appear as the same as the player character's equipped weapon.
