Returner

In 2084, soldier Milly finds herself in a desperate battle against the Daggra, a terrifying alien race threatening humanity's survival. As the fortress in Tibet is breached, she makes a fateful decision to jump into a time portal, hoping to change the course of fate and save her people.

Milly's jump through the time portal propels her into the chaotic world of 2002. She quickly realizes her mission to eliminate the first Daggra and prevent an invasion, setting a race against time in motion.

Milly lands unexpectedly in Tokyo Bay and witnesses a violent shootout involving a hitman named Miyamoto and notorious Triad mobster Mizoguchi. In a surprising twist, her arrival creates an opportunity for Mizoguchi to escape, leading to a complex relationship with Miyamoto.

After their chaotic first encounter, Milly devises a plan to force Miyamoto to help her in her mission. She tapes a bomb to his neck, creating a tenuous partnership fueled by their mutual goal of vengeance against Mizoguchi who had harmed them both.

In the evening, Miyamoto finds distressing clues about his fate, including photographs and a newspaper clipping that depicts his death. Confounded by these ominous images, he seeks advice from his weapon supplier Shi, who downplays the threat of the Triads.

Together, Milly and Miyamoto gather resources to locate the Daggra's crashed spaceship, only to find it has been moved to the National Institute of Space Science. Their planned infiltration of the facility is thwarted by Mizoguchi's arrival, throwing their mission into disarray.

Milly and Miyamoto come face to face with the alien they believe is their enemy. Instead of the feared monster, they discover that humanity's actions have provoked the war, as they had captured the alien first, complicating Milly's mission.

As Mizoguchi and his gang seize the alien and its ship, Milly and Miyamoto regroup for a final showdown. They understand the urgency of stopping Mizoguchi, who intends to exploit the alien technology for his gain.

A dramatic showdown occurs at an abandoned oil rig as Milly and Miyamoto confront Mizoguchi. Amidst explosions and chaos, Miyamoto seizes the moment to reclaim control, firing back and ultimately ending Mizoguchi's reign of terror.

A Daggra craft, disguised as a commercial airliner, arrives on the scene after the chaotic battle. The Daggra consequently rescue their injured comrade, leading to an unexpected resolution and Milly's gradual disappearance from reality.

In the aftermath of the battle, Miyamoto vows to leave behind his violent lifestyle and surrenders his weapons to Shi. This marks a pivotal moment in his life as he seeks redemption from the past he's left behind.

As Miyamoto heads home, he encounters a thug whose life he spared earlier at Tokyo Bay. Defenseless and unarmed, he faces a life-threatening situation until he discovers that a metal plate in his coat, identical to the one that saved Milly, intercepts the bullet.

The metallic plate bears a message from Milly, expressing her gratitude and confirming that she has fulfilled her debt to him by saving his life. This revelation brings a poignant closure to Miyamoto's turbulent journey.

Unbeknownst to Miyamoto, it is revealed that a future version of Milly had traveled back in time to ensure his survival. She discreetly placed the protective plate in his coat before returning to her timeline, thus completing a complex loop of fate.

As the timeline realigns, the impact of Milly and Miyamoto's actions resonates through history. They change not only the course of the alien invasion but also their destinies, leaving behind a legacy that would be remembered far beyond their immediate struggle.
