Description
Shin Hazama, a third-year high school student in contemporary Japan, suffers a devastating loss when his father dies, compelling him to move in with his uncle Tetsuya. Emotionally withdrawn since his mother's earlier death, Shin later discovers her passing resulted from a parallel world dynamic: the death of his counterpart's mother in the other world triggered his own mother's demise. His childhood friend, Kotori Izumi, steadfastly supports him despite his resistance to emotional connection.
Jin, Shin's counterpart, hails from a parallel Japan where feudal structures endure under Princess Kotoko's oppressive rule. Unlike Shin, Jin matures within a militarized society and embraces rebellion after his father's death. He crosses into Shin's world with a singular objective: kill Kotori. Jin believes eliminating her will end Princess Kotoko's life in his world due to the intrinsic life-link binding counterparts. His resolve is forged by witnessing widespread suffering under Kotoko, viewing his mission as a necessary act of liberation.
The two worlds are fatally intertwined; a death in one world claims the counterpart in the other, explaining unexplained fatalities in Shin's world, including his mother's. Jin's arrival shatters Shin's fragile stability, forcing him to confront his passivity. Shin initially struggles to accept the existence of a parallel self but gradually resolves to protect Kotori from Jin. Their conflict deepens as Shin comprehends Jin's motivations and the brutal consequences of the interconnected worlds. Shin's protective instincts towards Kotori and his growing awareness of Jin's trauma drive him to actively oppose Jin's plans.
Jin encounters obstacles beyond Shin, including Armatics (AI robots) and fixers like Miko and Riko, dispatched from the parallel world to halt him. Undeterred by these challenges, Jin remains fixated on his goal, seeing Kotori's death as an unavoidable sacrifice. The confrontation between Shin and Jin escalates as both grapple with their shared identity yet divergent paths, culminating in battles where each fiercely defends their choices and those they seek to protect.
