World Trigger (ワールドトリガー Wārudo Torigā), also known in short form as WāTori (ワートリ), is a Japanese manga series written and illustrated by Daisuke Ashihara, and serialized in Weekly Shōnen Jump since February 2013.

In Mikado City (三門市 Mikado-shi) (280 000 inhabitants), a "gate" to a different world is opened suddenly one day. Monsters called "Neighbors" (近界民（ネイバー） Neibā, lit. "Near-world people") start appearing from it, everyone is afraid of them because Earth's weapons don't work against them, but a mysterious group starts fighting off the Neighbors. They, the "Border" defense agency, create a defense system against the Neighbors. Since then, regardless of the Neighbors still emerging from the gates, people of Mikado City were living normally today. Four and a half years after the gate is opened for the first time, Yūma Kuga (空閑 遊真 Kuga Yūma), a humanoid Neighbor, comes to Mikado City, where he meets Osamu Mikumo (三雲 修 Mikumo Osamu), a Border agent.
