Last Man: First Love (2025 Film): Release Date, Story, Cast, Theme Song & Everything We Know | The Return of Japan’s Most Beloved Buddy Duo

🎬 What Is Last Man: First Love About?

In the original 2023 TBS series, viewers fell in love with the strangely perfect partnership between:

• Minami Hiromi (Masaharu Fukuyama) — the blind FBI agent known as “The Last Man,” called in when cases seem unsolvable.

• Godou Shintaro (Yo Oizumi) — a stubborn detective with zero patience but a fiercely loyal heart.

After cracking case after case, their relationship deepened — leading to the shocking twist that they are actually brothers. Fans cried, critics cheered, and demand for a sequel exploded online.

Last Man: First Love picks up two years later with a more emotional mission, more international intrigue, and the biggest threat they've ever faced.

❤️ A Case That Begins With His First Love

When Minami returns to Japan, he calls Godou to Hokkaido — where the story introduces:

Nagisa Ivanova (Rie Miyazawa)

Minami’s long-lost first love — a genius engineer with global acclaim, now running for her life.

She’s being chased by a powerful underground organization, and her only hope is asylum in the U.S. But her presence triggers a chain of events that spirals into a deadly international conspiracy.

As earthquakes shake the city, government agencies close in, and assassins hunt Nagisa, Minami, and Godou must protect the woman who once held his heart… even as old wounds reopen.

🔥 A Bigger, Higher-Stakes Mission

To save Nagisa and stop an unprecedented threat, the invincible duo teams up with:

• Ren Nagase as Godou Izumi

• Rowoon as Clyde Yun, a newly dispatched FBI agent

• CIA operatives

• Hokkaido Prefectural Police

But someone inside their circle is leaking information — and every step forward leads them deeper into danger.

This time, the enemy isn't just criminal syndicates.

It’s a conspiracy capable of shaking the world.

🎵 Theme Song: “Jupiter feat. Koshi Inaba” — A Collaboration Fans Didn’t See Coming

Masaharu Fukuyama, a musical powerhouse in his own right, delivers the theme song "Jupiter" featuring legendary rock vocalist Koshi Inaba (B’z).

Fukuyama describes the collaboration as “a creative explosion” inspired by Minami’s emotional journey. Koshi Inaba calls the process “luxurious and deeply meaningful.”

The song embodies:

• heartbreak

• resilience

• the emotional core of First Love

Expect it to chart the moment the movie releases.
