Grisaia: Phantom Trigger is a kinetic visual novel (no branching routes). As the latest entry in the Grisaia: Phantom Trigger series, Grisaia: Phantom Trigger introduces an all-new storyline and cast, created by the original team—character designer Akio Watanabe and writer Ryuta Fujisaki.

Main story:
At the newly built Mihama Academy, elite students hone their extraordinary skills—sometimes even in the middle of missions. Gunner Rena (nicknamed "Mad Dog"), sniper Juuka, demolition expert Chris, spy Maki, and their handler Haruto make up SORD: the Social Operations Research and Development department.
Mihama Academy now entrusts these so-called "misfit" girls with important missions no one else dares to take. They throw themselves into high-stakes, extrajudicial operations without hesitation, fighting for their country, for the future, and for each other, with no guarantee of safety.
A powerful, action-packed visual novel where duty and danger collide.
We follow Mihama Academy administrator Haruto, Issei Sengoku, Chihiro Ugawa, and other original Phantom Trigger members deep into the mountains to visit an old friend's grave.
There lies Haruto's master—Aoi.
They make this journey every year, and at first the car is filled with laughter. But as they near their destination, silence and regret well up, and memories of Aoi's life—a girl both fierce and pure—resurface.
Life is passed down from generation to generation.
"All things must perish, and life must fade. Entropy—that is the essence of everything."
What exactly brought about Aoi's final moment in this world?
