World Trigger is set in Mikado City, where a portal to another world has opened, unleashing monstrous creatures called Neighbors.
These Neighbors pose a significant threat, and ordinary weapons are ineffective against them.
To combat this menace, the Border Defense Agency was created, utilizing special weapons known as Triggers.
The story follows Osamu Mikumo, a Border trainee, whose life changes when a mysterious transfer student, Yuuma Kuga, arrives.
Osamu discovers that Yuuma possesses exceptional abilities and harbors a surprising secret related to the Neighbors, forcing Osamu to question everything he thought he knew about the conflict.
