After dying in a freak accident, Jett Lavine finds himself reincarnated into a strange, new world with a mysterious power accompanying him: the [Gacha System]. An ability that allows him to exchange currency for summons–able to choose from summoning weapons, permanent skills, or even familiars to fight alongside him, there is only one catch: it’s all up to chance. Left with this chaotic, but wildly powerful system, Jett decides to take on the challenges awaiting him within Fantasia in hopes of taking full advantage of his second chance at life, however, other trials await him. “The Reverse King”--a figure he is told about as a plague looming over the world of Fantasia; a reincarnated human like him, with other reincarnators serving under him, all with systems of their own.
