World Trigger Season 3 - What We Know So Far

The story of "World Trigger" follows Yūma as he becomes a part of Border, developing a solid group of dependable friends and learning to use his unique skills to help protect Mikado City. Yūma has a particularly difficult past, as his father sacrificed himself to make a Black Trigger for Yūma after the boy fell in battle and almost died. The Trion in the Black Trigger keeps him alive, and Yūma has a technological companion and protector known as Replica that follows him everywhere. 

Osamu, Yūma, and the rest of the Tamakoma Second aim to practice and train to rise to A-rank, with the goal of gaining Border's permission to visit the Neighbor world and take the fight to them, while also looking for a way to bring back Yūma's father, if possible. The beginning of Season 3 will pick up where Season 2 left off, in the middle of the manga's B-Rank Battles Arc, during which Yūma and the rest of Tamakoma Second fight against other Border agents for the chance to move up to A-rank. Throughout his time in Border, Yūma has developed strong relationships with the rest of Tamakoma Second and is intensely loyal to his friends, intent on protecting others against the Neighbors and stopping the fighting altogether. 

With Season 3 of "World Trigger," there is the possibility that the anime may catch up to the manga in terms of story, so many fans wonder if there might be another anime-only story arc coming up as well.
