Manga Monday – World Trigger

World Trigger, also known in short form as WorTri, is a Japanese manga series written and illustrated by Daisuke Ashihara, which was initially serialized in Weekly Shōnen Jump from February 2013 to November 2018, and later transferred in December 2018 to Jump Square. An anime adaptation of the series produced by Toei Animation started airing on October 5, 2014; the series ended on April 3, 2016.

The manga was written and illustrated by Daisuke Ashihara. Individual chapters have been serialized in Weekly Shōnen Jump since February 2013, and are collected into tankōbon volumes published by Shueisha. As of June 2019, twenty volumes have been released in Japan. Viz Media has licensed the series. Due to health issues on the part of the author, it was put on hiatus after the 50th issue of 2016. The series returned in issue #48 of Weekly Shōnen Jump on October 29, 2018 and ran until issue #52 on November 26, then it was transferred to Jump Square on December 4, 2018.

In the year of 2016, a survey conducted by Oricon found that World Trigger was the 18th best-selling manga, with about 2,234,851 copies sold. Rebecca Silverman of Anime News Network said that “World Trigger is an exciting read that distributes its information organically rather than relying on info-dumps.” In a 2016 reader’s poll on goo, the series ranked the fifth most likely to become a Weekly Shonen Jump signature series. However, the anime received criticism stemming from Toei’s handling of the adaptation. Gabriella Ekens from Anime News Network referred to the production as “incompetent” and “baffling”, stating “World Trigger isn’t a bad show, but it’s a terrible adaptation.”


In Mikado City (280 000 inhabitants), a “gate” to a different world suddenly opens one day. Monsters called “Neighbors” start appearing from the gate. Humans are overwhelmed at first when their weapons are found to be useless against Neighbors, until a mysterious organization appears that is able to repel the Neighbors’ attacks. The organization is called the National Defense Agency, or “Border,” and has appropriated the Neighbor technology called “Triggers,” which allows the user to channel an internal energy called Trion and use it as a weapon or for other purposes. By activating a trigger, the body of users is replaced by a battle-body made of trion which is stronger and more resistant. Members of Border are divided in three ranks, A, B, and C, with only the members of rank A possessing the most powerful triggers, comparable in strength to those of Neighbors.


Four years later, people in Mikado City have grown used to the occasional battles with the Neighbors, and have returned more or less to their everyday lives. Border has become popular. One day, a mysterious white-haired student transfers to the local school, named Yūma Kuga. Kuga is in fact a strong humanoid Neighbor, a fact that he wants to hide from Border. In the school he meets another student, Osamu Mikumo, who is secretly a C-class Border trainee. Since Kuga is completely oblivious about life in Mikado City, it falls to Mikumo to guide him through it, and to prevent him from being discovered by Border.
