About four years have passed since a gateway to another realm unexpectedly materialized within Mikado City, bringing with it beings known as the Neighbors.

The lines between Border’s perception of the Neighbor Yuma and Osamu's own understanding blurred; where Border saw an enemy, Osamu struggled to find malice. A fragile trust began to develop between the two boys, pulling Osamu into a conflic…

As a gate tore open near Osamu's school, right on the edge of the Forbidden Zone, Trion Soldiers, deployed for combat, launched their attack. Anxious about his own capabilities, Yuma attempted to dissuade Osamu from engaging, yet the young …

Osamu receives little praise and considerable reprimand when he asserts that he has vanquished Trion Soldier Marmod. In reality, he’s shielding Yuma, the Neighbor. Kitora, a Border Agent of A-rank, is deeply frustrated with Osamu's unauthor…

With a daring leap, Kitora launched herself onto the back of Ilgar, a newly developed Trion Soldier, as it soared through the air, poised to strike the city below. In an instant, Ilgar shifted, initiating a self-destruct sequence and plumme…

The urgent task facing Yuichi and Osamu – investigating the anomalous gateway – weighs heavily on Osamu's shoulders. Separately, Yuma, acting upon Replica’s counsel, begins an inquiry of his own. The following morning brings a significant e…

Osamu extended his hand toward Yuma and Replica. From Yuma, he and Chika gleaned vital details concerning the Neighbors, only to be abruptly confronted by two A-Rank operatives, Shuji and Yosuke. The agents were hunting for a Neighbor disgu…

Without so much as a word of inquiry, A-rank operatives Shuji Miwa and Yosuke Yoneya launched an attack against Yuma. Sensing the unfolding crisis, Osamu reached out to Jin for assistance.

Following the complete rout of Shuji’s unit, the leaders of the Border Agency demand that Yuichi confront Yuma and retrieve the Black Trigger. As Yuichi prepares for this inevitable confrontation, Osamu expresses his concern, unaware that a…

Jin urged Yuma to transfer to the Tamakoma division, and Yuma agreed, provided he could work alongside Osamu and Chika.

Osamu learns from Replica the reason for Yuma’s arrival in this world, and from Chika, a glimpse into the depths of her true feelings.

Driven by a shared ambition, Osamu, Yuma, and Chika resolved to enlist with the Tamakoma branch, aiming to serve as A-rank operatives within the Neighboring World Expeditionary Force. To achieve this designation, they embarked on an intensi…

Commander Kido harbors a growing concern that the Tamakoma branch is accumulating excessive power. As a result, he has issued an order for A-rank operatives stationed at headquarters to secure Yuma’s Black Trigger.

The clash between the A-Rank assault team and Yuichi Jin ignited. Confronted by operatives of the highest caliber, he sought to prolong the engagement, turning it into a grueling test of stamina. Yet, as Shiro Kikuchihara managed to evade h…

With the Black Trigger now fully engaged, Yuichi unleashes his devastating "Wind Blade" technique. As his struggle against the seasoned A-Rank fighters Kei and Soya intensifies toward a decisive moment, the Arashiyama Unit arrives to lend t…

Yuichi Jin and the Arashiyama Unit fought back against the encroaching force. Word reached Border Agency headquarters of the elite squad’s failure, and a palpable tension began to settle within its walls.

The day arrived for Yuma and Chika’s formal induction into the Border Agency. Osamu stood nearby, a knot of nerves tightening his stomach as they faced the assessing gazes of their fellow agents. Then, at that moment,

A sense of anticipation settled over Osamu as he prepared for his sparring match with Soya Kazama. Kazama embodied an almost intimidating power, whereas Osamu hadn't managed to connect a single blow across more than twenty previous encounte…

Osamu found himself adrift, unsure how to navigate his sudden notoriety—the man who’d drawn even with Soya Kazama. The unexpected attention quickly manifested in a challenge: another agent proposed a Rank War, and Osamu knew he couldn't ign…

The confrontation between Yuma and Shun Midorikawa unfolds. Beneath a veneer of calm, Yuma seethes over Shun’s public dismantling of Osamu, a deeply embarrassing spectacle. Now, he must face an A-rank veteran – but how? Elsewhere, Commander…

Kizaki, Karauma, and Konami battled the menacing Hyuse and Viza, creating a diversion so Osamu and Chika could flee. Simultaneously, Ranbanein swiftly overcame the Chano unit and turned his attention to Yoneya, Izumi, Midorikawa, and Azuma,…

Kizaki had discerned Hyuse’s Trigger, Lambiris. He then instructed Karasuma and Konami to safeguard the city, intending to confront and delay Hyuse and Viza himself.

Viza and Hyuse relentlessly pressed their pursuit of Chika, but Yuma and Jin arrived at a crucial moment. Yuma confronted Viza directly while Jin engaged Hyuse. Meanwhile, Osamu and Karasuma guided Chika and the C-rank agents toward Border …

Director Shinoda managed to isolate Enedora within the virtual training facility. Yet, the sheer force of Enedora’s Black Trigger proved overwhelming, easily deflecting the coordinated assaults of the Border agents. Simultaneously, Karasuma…

Karasuma deployed his own specialized ability, Geist, targeting Hairein. The effect granted him a surge of power and enhanced reflexes, though at the cost of a rapidly diminishing window – he had just two hundred seconds remaining to mainta…

Miwa unleashed her Trigger, Lead Bullet, upon Hairein. Simultaneously, Yuma resolved to launch a reckless assault on Viza.

Yuma secured victory over Viza, though he retains a measure of his power. A sudden action by Mira separated Miwa from Osamu. Only seven seconds remain before destiny shifts irrevocably!

The Afterlife Force retreated from our world, and the second major invasion has concluded. Though Chika was rescued, Osamu fell unconscious. In his dreams, Osamu recalls the reasons that led him to join Border.

When Osamu awoke, he spoke with Yuma, piecing together the events from his mother and Chika. Shortly thereafter, a senior member of Border, Karasawa, escorted him to the agency’s scheduled press conference.

Journalists frequently pressed Border’s leadership regarding accountability for the destruction wrought by the recent conflict. Osamu learned of Netsuki’s strategy through Karasawa, and subsequently addressed the assembled reporters, sharin…

Before a subdued Osamu, Yuma and Chika secured Tamakoma Second Unit’s first victory in a Rank Battle. Now, they face the formidable Suwa Unit, ranked eighth, and the equally challenging Arafune Unit, holding tenth place. Osamu finds himself…

Osamu made a full recovery and returned to his company. This time, Tamakoma Second was granted the privilege of selecting their deployment zone, and they opted for an elevated urban environment ideally suited for snipers.

The encounter appeared poised to reward whichever side held the advantage in sniper specialists, yet the Arafune Unit found itself increasingly boxed in by the other two. Having once been an aggressor himself, Arafune initiated a sudden ass…

Tamakoma Second’s upcoming matches pit them against the Nasu Unit, currently ranked thirteenth, and the formidable Suzunari First Unit in ninth place. During this series, Yuma will have the opportunity to issue a challenge for a one-on-one …

The complications stemming from Murakami’s influence proved particularly difficult. Osamu found himself considering how best to prepare for the coming Rank Battle.

The commencement of the Rank Battle was signaled. The Nasu Unit proceeded with their pre-arranged tactical maneuvers amidst the raging storm. Yet, a single, precise shot from Chika’s rifle irrevocably altered the course of events.

The operatives were split, positioned on opposite banks of the river—east and west. A fierce, three-sided engagement is now unfolding among the attacking force on the western shore.

To the east, Kuruma and Betsuyaku were vulnerable to Nasu’s attacks. Determined that they wouldn’t fall before his own demise, Osamu offered what assistance he could. Meanwhile, on the western flank, Yuma seemed to relish the challenge of b…

With a sharp cry, Chika shattered the riverbank, diverting its waters toward the city. Osamu urged Yuma to hasten his arrival.

With Mikumo Squad’s ascension to the upper echelons of the B-rank, the battles against their most formidable peers would serve as a crucial test for advancement to the A-rank. Foreseeing this challenge, Osamu wrestled with his persistent fa…

The latest story arc of *World Trigger*, titled "Toubousha Arc," has begun. Unidentified combatants, wielding Trion energy, suddenly appeared at Border Headquarters. Jin and Tachikawa immediately moved to confront them.
