World Trigger is a sci-fi action TV anime produced by Toei Animation, directed by Mitsuru Hongo, with series composition by Hiroshi Ohnogi, based on the manga by Daisuke Ashihara. Set in a world under constant threat from interdimensional invaders known as Neighbors, the series follows Osamu Mikumo, Yuuma Kuga, and Chika Amatori as they rise through the ranks of the Border Defense Agency. With a sprawling cast including elite agents like Kei Tachikawa and Yuuichi Jin, the story delivers intricate tactical battles and compelling character dynamics that reward long-time fans and newcomers alike.

Mikado City was forever changed the day an interdimensional gate tore open without warning, unleashing beings known as 'Neighbors' upon the unsuspecting population. Unlike any threat humanity had faced before, these extraterrestrial invaders proved completely immune to conventional weaponry, leaving the world vulnerable. Standing between civilization and annihilation is a secretive organization called 'Border,' whose agents wield mysterious weapons known as 'Triggers.' Four years have passed since those first terrifying encounters, and life in Mikado City has settled into an uneasy new normal. When transfer student Yuuma Kuga crosses paths with his classmate Osamu Mikumo during a sudden Neighbor attack, an unexpected encounter unfolds. Osamu, a Border agent operating under the radar, finds himself pushed to his limits. Yet it is Yuuma's response to the crisis that raises the most questions—because the new kid in town may be harboring a secret that blurs the line between humanity and the very threat Border was created to fight.
