In a world of swords and magic, evil crime syndicates known as Dark Guilds terrorize the Kingdom of Efan. The most secretive and feared of them all is the Messianic Legion, Yerkchira—but its guildmaster is an ordinary, normal, harmless little guy! Despite his wishes for peace and happiness, the lovely ladies under his command have big plans for him, and he finds himself at the brink of a great destiny! This average individual is the center of a campaign for diabolical global domination—while remaining none the wiser himself.

Not long after their encounter with the group of heroes, the master, who had finally found a sense of peace, was accompanying the slime girl Soulgross on a new mission. At her request, they set out to acquire the legendary elixir, a universal panacea rumored to cure any ailment. However, their quest was threatened by the evil crime guild "Heinichen, the Steel Matriach," which had been ordered by the prince of the Efan Kingdom to eliminate the "Yerkchira, the Messianic Legion" and disrupt their plans.
