World Trigger (Subtitled)

A gate to another world opened in Mikado City. Invaders from another dimension, referred to as Neighbors, overran the area around the gate, leaving the city gripped by fear. However, a mysterious group suddenly appeared and repelled the Neighbors.

The Miwa Squad rushes into battle only to find a defeated giant laying in the aftermath. Bewildered, Osamu falls into ranks with the boy-Neighbor Yuma, whose reckless ways attract new threats. As danger closes in, the two begin to trust each other.

Combat-use Trion Soldiers attack when a gate opens in Osamu’s school just outside of the Forbidden Zone. Worried he’s not strong enough, Yuma tries to stop Osamu from fighting back, but Osamu’s determination to save the other students is limitless.

Kitora boldly jumps onto the back of Ilgar, a new type of Trion Soldier, while it’s mid-flight and bent on attacking the city below. Suddenly, Ilgar transforms, enters self-destruct mode and plummets toward its target. How will she escape now?!

Yuichi and Osamu's critical mission to investigate the abnormal gate puts a lot of pressure on Osamu. Meanwhile, Yuma follows Replica’s advice and conducts an investigation of his own. The next morning, Osamu and Yuichi have a fateful meeting with Yuma.

Osamu reaches out to Yuma and Replica. He and Chika learn some critical information about Neighbors from Yuma, but they're soon discovered by two A-Rank agents, Shuji and Yosuke; they're searching for a Neighbor in human form.

Shuji and Yosuke are soon joined by two snipers and they wage a four on one battle against Yuma. Osamu seeks help from Yuichi for the human-form Neighbor but is told to stand down. Can Yuma defeat four A-Rank Agents all by himself?!

With Shuji's squad singlehandedly defeated, the Border Agency's executives order Yuichi to defeat Yuma and recover the Black Trigger. Osamu worries about Yuichi's impending clash, while a secret hidden by Yuma is slowly exposed.

Yuma is invited to join the Border Agency’s Tamakoma Branch, and agrees on the condition that Osamu and Chika join with him. Surrounded by elite agents at the Tamakoma headquarters, Osamu can't help but feel uneasy.

Yuma's revealed why he came from the other world. Chika's resolved to join the Border Agency so she can go to the other world in search of her friend and her older brother. What will Osamu do now that he's learned Yuma's secret and Chika's true purpose?

Osamu, Yuma and Chika set their sights on joining the expeditionary force. First, they'll need to win a tournament called the Rank Wars. In preparation, they start training under seasoned A-Rank vets Reiji Kizaki, Kyosuke Karasuma, and Kirie Konami.

Yuichi and Yuma join forces...while Commander Masamune begins to fear the power gathering in the Tamakoma Branch. He orders his elite unit to seize the Black Trigger. Now, the only thing standing in the way of their prize is the powerful Yuichi Jin.

The battle between the A-Rank attack unit and Yuichi Jin begins to rage. In the face of top-level agents, Yuichi tries to turn it into a test of endurance. But just as Shiro Kikuchihara gets by him, Yuichi's Black Trigger goes off!

Yuichi finally reveals his "Wind Blade" technique with the Black Trigger. As his battle with A-Rank vets Kei and Soya reaches its climax, the Arashiyama Unit shows up in support and clashes with the Miwa Unit. Who will emerge victorious?!

Yuichi Jin and the Arashiyama Unit repel the enemy. Receiving news of their elite squad's defeat, the Border Agency's headquarters starts to get nervous. At that moment Yuichi appears in the conference room and proposes a deal to Commander Masamune!

The day of Yuma and Chika's initiation into the Border Agency arrives. Osamu nervously stands by in support, while they draw the scrutiny of their new peers. At that time, A-Rank third unit leader Soya Kazama challenges Osamu to a battle!

Osamu readies for his practice fight against Soya Kazama. Soya is a symbol of overwhelming strength, while Osamu has yet to land a hit in over twenty battles! Osamu's feeling totally helpless, when something Soya says lights a fire under him.

Osamu doesn't know how to deal with his new reputation as "the guy who tied with Soya Kazama". He is soon challenged by one of his fellow agents to a Rank War. A huge crowd gathers and Osamu is about to be thrown into another battle...!

Yuma and Shun Midorikawa's fight begins. Yuma quietly rages over Shun's humiliating public defeat of Osamu. How will he fight against the A-rank vet? Meanwhile, Commander Kido convenes a meeting to prepare for the forecast massive Neighbor invasion.
