An isekai that's fun for the whole family! Well… not for the family of Dustin, a 24 year old office worker, who while out with his family are caught spectating a dangerous police chase. As they get a closer look, quickly approaching is a tractor trailer driven by a man who looks to be Dustin's… robot doppelganger? This double has a vendetta, and quickly darkness sets over Dustin. He then finds himself tied to a dinky boat barreling down a raging river with an eccentric group of hostages. It seems Dustin finally gets his isekai dream; or is this his specially crafted hell. Struggling to acclimate to this new world, he learns that his family ended up here too. His brother, Zander, gains audience with the King, and finds out that a pair of brothers are waging war upon the kingdom and each other. According to the King, the two brothers are alternate versions of the immortal brothers wreaking havoc! And are now tasked with the elimination of their otherworldly selves. The King gives Zander a special task, and a stern warning, which may alter his perception of his brother and complicate their quest. Something sinister is brewing in this world and how will these two brothers find a way to handle this monumental task ordered by the King?
