World Trigger Volumes 1 and 2 by Daisuke Ashihara

World Trigger starts out with a very Attack on Titanesque set-up, expressed simply in one page. Monsters from another dimension are invading the earth. A paramilitary force shows up to fight the monsters. Daily life for the rest of humanity is often interrupted by these “Neighbors” who look a bit like giant eels and the humans who fight back against the invasion.

Osamu is a bit of an unassuming student, but he finds his life complicated when a mysterious new transfer student named Yuma shows up. Yuma seems to not know very much about basic human behavior. When a Neighbor attacks outside of the usual boundaries, Osamu reveals that he’s actually a trainee for the Border Defense Agency, with a small amount of power that he’s determined to use to protect everyone in his city. Yuma turns out to have some extraordinary powers himself. He claims to also be a Neighbor, from the dimension where the monsters come from. He also has the ability to use a trigger, the weapon/body exchange protocol that allows users to fight off the monsters.

In the ensuing battle, Yuma fends off a powerful monster after Osamu proves not to have the level that he needs in order to destroy his enemy. Osamu turns to helping out however he can, by evacuating residents and helping everyone stay safe. Members of the Border Protection Agency turn up, suspicious of the recent events and determined to follow correct bureaucratic procedure. The cast of the book gradually expands beyond Osamu and Yuma to include many of the typical foils for a shonen protagonist. There’s a cool older male mentor, a type A overachiever warrior girl, and a host of bureaucrats in the Border Protection Agency that will surely make life difficult for Osamu.

The Border Protection Agency seems more chaotic than a force for either good or evil, as a squad starts to hunt down Yuma. Osamu tries to intercede, but Yuma’s level of power is such that he’s able to evade attack from multiple agents at once with only some slight injuries. One interesting aspect of the story is that Osamu keeps getting promoted within the Border Protection Agency simply because he is often in the right place at the right time and occasionally forced to take credit for some of Yuma’s actions in order to maintain his new friend’s cover. Osamu’s leveling up though being an unassuming nice guy who is incredibly lucky is a bit unexpected for a reader expecting a more typical brash shonen hero, and this was one aspect of the book that I found intriguing.

There’s a fair amount of world building as the characters go into details about the alien tech infused battle system, but I didn’t find this very interesting. The art is workmanlike and easy to follow, but it doesn’t have that extra bit of style or distinct quality that would make me want to pick up the manga just to see some fabulously paneled battle scenes. The story is solid, but there isn’t much that’s surprising about it so far. The anime for this series is starting to air, so I imagine that will fuel interest for this title. I didn’t find myself inspired to keep reading the series, simply because there are other titles out there that are much more entertaining. I can read One Punch Man if I want something funny, Attack on Titan if I want to read about a dystopian future where humanity is fighting off giant invaders, or Seraph of the End for more attractive art and interesting world building. Overall, this is a solid if not super compelling shonen title, and I imagine that someone less picky about shonen manga than me will enjoy it.
