World Trigger

When a mysterious portal erupts in Mikado City, hostile extraterrestrials known as Neighbors pour through, impervious to conventional weapons. Humanity’s only hope lies with the secretive Border organization, whose agents wield high‑tech devices called Triggers to level the playing field. Four years later, the city has adapted to the constant threat, and everyday life coexists with the looming danger.

New transfer student Yuma Kuga teams up with classmate Osamu Mikumo, a hidden Border operative, during a sudden Neighbor incursion. As Osamu’s Trigger falters, Yuma reveals his true allegiance—he’s a defector from the alien side—turning the battle on its head and hinting at deeper inter‑world intrigue.
