Shinoda announces an imminent invasion by a new Neighbor country. Tachikawa and Kazama Squad are assigned to deal with the threat, based on Jin's predictions. Osamu follows Jin's suggestion to add a new member to Mikumo Squad.

Yuma faces Kageura. Ninomiya takes advantage of this to attack them both. After the battle, Osamu is devastated by his defeat. Kazama's advice leads him to make a major decision for the sake of the team, just as a new threat approaches Mikado City.

Soon after meeting and parting with Xeno and Lilith, Yuma, Osamu and Chika begin preparing for their promotion battle.

Xeno's hand cuts thin air, and monster Gieve takes in Lilith and takes on a grotesque form.

Giev's secret is revealed. Just like Lilith, he's a Humanoid Trion Soldier created by Lamia. Meanwhile, all of Shizuka City's citizens become Charon's hostages. Tachikawa, Kazama and other A-Rank Border agents gather in Shizuka City for the coming battle.

Zeno's devotion to Lilith leads him to treat Yuma and Chika like tools, enraging Osamu. Meanwhile, Gieve and Karon threaten Shizuka City with massive Trion soldiers! As Osamu's team joins Kitora in defending the city, Gieve isolates Osamu and Zeno.

While studying with Yoneya and Kodera, Miwa sees young siblings and is reminded of his past. The peace is shattered by an attack from Gieve's Spider-type Trion Soldiers.

Despite Lilith's best efforts, she can't hide her loneliness. Chika and Osamu work with Kitora and Midorikawa to try and cheer her up. At that moment, Karon and Gieve make their move, commanding Trion soldiers with special abilities.

Kazama Squad heads into combat as Gojima City is attacked by new Trion soldiers. Osamu tries to befriend Zeno and Lilith. Zeno offers to reveal his past, if Osamu will agree to a one-on-one fight. How far will he go to learn the truth about Elgates?

Zeno, a refugee from Elgates, begs Yuma and Osamu to harbor Lilith and him during their stay in this world. With Chika taken hostage, Osamu and Yuma have no choice but to agree. As they return to the Shizuka City retreat, an unseen assassin strikes!

Unknown Trion soldiers show up at Border HQ. Jin and Tachikawa take them on.

Mikumo Squad joins the B-rank upper tier. The fight against the top B-rank squads will be a touchstone for promotion to A-rank. Anticipating this, Osamu struggles with his inability to score a single point on his own and comes to a conclusion.

The team members are divided due to Chika dropping the bridge. While Osamu goes after points on the east side, Yuma faces off against Murakami and Kumatani in a triple-attacker showdown in the west. The stakes are high for all teams. Who will win?

Round 3 begins in a violent storm. While Mikumo Squad and Kuruma Squad focus on finding each other, Nasu Squad carries out their strategy as planned. Just as Nasu Squad seems to have the advantage, Chika's Ibis strikes. Can Mikumo Squad grasp victory?

Shocked to learn that Yuma lost in a solo rank battle, Shiori explains Murakami’s Side Effect. The other units prepare for Nasu Squads stage selection.

Kizaki has figured out Hyuse's Trigger, Lambiris. He orders Karasuma and Konami to protect the city while he holds off Hyuse and Viza. Viza acknowledges the skilled Kizaki as a worthy opponent, and decides to use Aftokrator's national treasure!

Kizaki, Karauma and Konami fight the sinister Hyuse and Viza so that Osamu and Chika can escape. Meanwhile, Ranbanein easily defeats Chano unit and takes on Yoneya, Izumi, Midorikawa and Azuma's combined forces. Can Jin's worst case scenario be prevented?

Aftokrator's humanoid Neighbors are unveiled. These so-called Horn Triggers overwhelm the Border agents with powerful Triggers! The A-rank Kazama Unit uses Kikuchihara's Side Effect in a skillful combo play against Enedora, but will their luck continue?

The C-rank units are revealed to be the true target. The battle intensifies as Hyrein sends humanoid Neighbors Enedora and Ranbanein into combat. Osamu fights to give the C-ranks a chance to escape, but Rabbit's merciless attack on Chika continues!

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.

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.

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!

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.

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.

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?

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.

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.

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?!

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...

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...

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?!

Osamu gets more trouble than credit when he claims to have defeated Trion Soldier Marmod. Really, he's covering for the Neighbor, Yuma. Kitora, an A-rank Border Agent, is furious with Osamu for stepping out of line... But does she suspect the truth?

Border sees the Neighbor Yuma as an enemy… but Osamu is unable to view him as someone with hostile intentions, and trust begins to bloom between the two boys. Osamu finds himself caught between his own thoughts and the rules of the organization he belongs to, Border.
