Ep 1. Visitor from the Other World

In the first episode of the popular anime World Trigger, titled "Visitor from the Other World," we are introduced to a world where half a century ago, a mysterious gate to a parallel world appeared in Mikado City. This parallel world is known as the "Neighborhood," and through this gate, strange and powerful creatures known as "Neighbors" began to invade the human world.

The story follows a high school student named Osamu Mikumo, who lives in Mikado City and dreams of becoming a member of the Border Defense Agency. This agency is tasked with defending the human world from the Neighbors, and Osamu has a personal connection to this mission as his late father was a Border agent.

However, Osamu is not a typical high school student - he is actually a member of Border, operating undercover in the human world. When he encounters a mysterious new student named Yuma Kuga, who seems to have abilities beyond those of a normal human, Osamu realizes that something strange is going on.

As it turns out, Yuma is actually a Neighbor - but not like any Neighbor that humans have encountered before. Yuma belongs to a rare species of Neighbor called a "Black Trigger," and he has come to the human world with a personal mission of his own. Despite the potential danger that Yuma poses, Osamu decides to help him, believing that Yuma may hold the key to discovering more about the Neighbors and how to defeat them.

Meanwhile, the Border agency is dealing with a new threat from the Neighbors - a powerful monster known as a "Trion Soldier" has appeared in Mikado City, wreaking havoc. With their current agents unable to defeat the Trion Soldier, Border is forced to call upon their elite unit, known as "Tamakoma Branch," to handle the situation.

As the episode progresses, we see Osamu and Yuma team up to try and track down the Trion Soldier and put a stop to its rampage. Along the way, they encounter various other Border agents and Neighbors, including an enigmatic figure with ties to Yuma's past.

The action is fast-paced and intense, with plenty of cool fight scenes and special powers on display. But what really sets World Trigger apart is its intricate worldbuilding and attention to detail - there's a real sense of thought and care put into creating a believable universe that feels unique and interesting.

Overall, "Visitor from the Other World" serves as a great introduction to the world of World Trigger, setting up the major players and establishing the stakes for the rest of the series. It's a great starting point for anyone looking to get into the show, and should leave viewers eager to see what comes next.
