On his first day with Special Fire Force Company 8, Shinra Kusakabe, a third-generation pyrokinetic who is able to produces flames from his feet, meets his fellow company members and begins to fulfil his wish of becoming a hero.

Arthur Boyle, the self-professed “Knight King,” arrives at Company 8, and immediately, there are tensions between him and Shinra. With the Rookie Games coming up, Hinawa wants to see what the two new recruits are really capable of.

Shinra and Arthur compete in the Rookie Fire Soldier Games, a contest to test the abilities of each year’s newest recruits. However, they are interrupted at the goal by the mysterious man who created explosions at their last fire scene.

A call mistakenly comes in to Company 8 to rescue a dog out of a tree, to which Shinra and Arthur respond. However, when an Infernal suddenly appears at the district courthouse, the two must play catch-up to join the rest of the company.

While jogging, Shinra inadvertently disturbs Iris’s purification rite, and sees that she is troubled. When Iris later turns up missing, the other members of Company 8 rally to Company 5’s compound, to which Iris had secretly slipped away.

Shinra confronts Hibana in an attempt to rescue Iris, and must once again deal with her ability to make his body shut down. The story of Hibana and Iris’ youth as orphans, as well as Hibana’s rise to prominence, is revealed.

The members of Company 5 and 8 get together for a cookout, ostensibly to celebrate a successful nighttime training exercise. Using the bylaws of the Special Fire Force, Obi gets Shinra and Arthur temporarily assigned to the 1st to investigate it.

Obi goes over Hibana’s research, and learns that the artificially-created Infernals she dissected all had traces of insect DNA in them. Shinra and Arthur’s investigation at the 1st continues, and they finally get their first lead on a culprit.

Tamaki watches on as Shinra confronts Rekka over his actions, and reminisces about how she once looked up to the lieutenant. Rekka reveals his objective in seeking out compatible children, one which could spell disaster for the entire world.

A captains’ conference is convened to allow the Special Fire Force to discuss the situation with the Evangelist and the White-Clad. Shinra once again has an encounter with Joker, in which startling information about Shinra’s brother is revealed.

While Company 8 searches for clues about the Evangelist, Hinawa recounts the tale of how the company originally came into existence. A lead prompts the crew to pay a visit to Company 7’s jurisdiction in Asakusa, and its captain, Benimaru.

Company 8 pitches in to help rebuild Asakusa after the latest Infernal incident, helping to gain the trust of its people. However, a White-Clad plot threatens to undo all of their goodwill, prompting Obi to take matters into his own hands.

With Konro’s help, the members of the 8th begin investigating events in the 7th’s jurisdiction. Chaos breaks out one dozens of cases of mistaken identity crop up, and the town’s people turn on each other. The 8th comes under White-Clad attack.

As Asakusa burns around them, Konro encourages Benimaru to step into his role as a community leader. Benimaru devises a way for the townspeople to foil the designs of the impostors among the crowd. Konro reaches out to Shinra for help.

Viktor Licht is assigned to Company 8 as its forensic scientist, but he is viewed with suspicion, since the assignment came from Haijima. Obi sends Shinra, Arthur and Iris to speak to a man named Vulcan about joining the 8th as its engineer.

Vulcan teaches Yu a lesson in the importance of forging things that cannot be broken, and his hope to create similarly unbreakable family ties. Sensing a threat to Vulcan, the members of Company 8 take up positions to keep him safe.

While Dr. Giovanni continues to search Vulcan’s workshop, Hibana comes to Shinra’s aid, allowing him to rush back to help Vulcan. Meanwhile, Arthur has his hands full trying to deal with Mirage’s illusions, and Iris resists in her own way.

Vulcan gets settled in at the 8th, while Captain Obi meets with Hibana, Konro, and Karim to exchange data on the White-Clad matter. Konro proposes that Shinra and Arthur be given combat training in Asakusa to improve their fighting skills.

Licht’s analysis of the attack on Vulcan’s workshop reveals that the Evangelist’s men have been in the “Nether,” the area beneath Tokyo. Company 8 proceeds underground in search of the White-Clad and the secrets behind human combustion.

Hinawa comes upon an abandoned subway station, where he gets into a shootout with Arrow. Arthur and Mirage find themselves in a rematch, as Arthur gets the chance to put the training he received from Benimaru and Konro to the test.

Obi and Vulcan face off against Dr. Giovanni and Lisa, during which Giovanni tells Obi more about the nature of Adolla Bursts. Shinra has an unusual experience that leads him to find Sho, but their reunion proves more volatile than hoped for.

As Shinra and Sho continue to share their Adolla Link, Shinra learns a startling truth about the origin of his Adolla Burst flame. Shinra comes to understand the Link’s nature further, developing his skills even more in his effort to reach Sho.

Shinra revisits his childhood to share his memories with Sho, to try to forge a deeper connection. When one of their own is critically injured, the members of the 8th rally to the rescue, and turn to Captain Huang of the 6th for assistance.

Before being discharged from the hospital, Shinra is visited by Captain Burns, who offers to tell him all about the fire that happened 12 years ago, but only if Shinra can demonstrate that he is strong enough to hear the whole truth.

Company 8’s junior crewmen take in a day of shopping for some new clothes for Lieutenant Hinawa, but their excursion is interrupted by the appearance of a giant Infernal. The 8th prepares for the annual Special Fire Force beefcake calendar shoot.

Shinra is approved to have a meeting with Company 4 Captain Hague, who may be able to provide information on the Evangelist and Adolla Bursts. However, once the meeting starts, nearly everyone involved begins behaving erratically.

Obi goes to see the chief with news of a fifth Adolla-Burst bearer. Schoolgirl Inca, who has the ability to sniff out fires before they start, becomes notorious as the Fireground Thief, extorting valuables from victims in exchange for rescuing them.

A widespread outbreak of fires stretches the members of Company 8 thin. Shinra tries to keep Charon and his men from taking Inca. With a shortage of ecclesiastical assistance, the crew members cannot put the Infernals to rest fast enough.

Shinra makes an important discovery about how to fight Charon, but incorporating a new hand form into his fighting style proves difficult. The other Fire Soldiers put into action a novel approach toward putting to rest a demon Infernal.

Inca is faced with the decision of whether to go with Shinra and the Fire Force, or to go with Charon and side with the Evangelist. Fed up with always being a step behind the Evangelist’s men, the 8th launches a research expedition to find answers.

The task force arrives on the Chinese Peninsula, and sets off through inhospitable territory toward a spatial rift that they hope will provide the answers they seek. They pick up an unexpected companion along the way who agrees to be their guide.

Shinra hears a voice via an Adolla Link. Scop tells the team about a mysterious woman in black robes that taught him how to speak, and who repaired the Tabernacle. The team’s mission takes a turn when intelligent Infernals show up at the Oasis.

Pan, Arthur and Licht continue to investigate the inside of the Tabernacle, while outside, the rest of the team have their hands full fighting off an Infernal attack. Shinra has an idea as to how to beat them, but needs Ogun to buy him some time.

Through Adolla Links and the assistance of Grace, Shinra learns more about the Evangelist and views Tempe’s memories. The team completes their investigation into the Tabernacle, but draw some unsettling conclusions from what they learn.

After reporting their findings to Obi, the team is dismayed to hear that their discoveries are being quashed by the church, prompting Licht to turn to unofficial channels. Joker approaches Benimaru with a proposition concerning the Holy Sol Temple.

Joker and Benimaru break their way into the church in search of the hidden scriptures. When Benimaru presses Joker for answers as to how he knows so much, Joker tells him about his past, revealing some dark secrets about the Holy Sol Temple.

Burns confronts Joker and Benimaru, then offers them the scant leads he has uncovered during his own personal probe of the Holy Sol Temple. Konro reports Benimaru’s findings to the 8th, and the target of their next investigation becomes clear.

Licht reveals to the other members of the 8th that he has been spying on them for Haijima. Licht and Shinra come up with a plan to get inside the child pyrokinesis lab where Shinra was institutionalized as a child to uncover some dirt on Haijima.

At Licht’s signal, the rest of the 8th breaks into the Haijima compound, where Vulcan and Maki confront an overpowered puppeteer. The rest of the company meets up with Shinra and Licht, who are facing Kurono, when a third party shows up!

The three-way battle between Haijima, the White-Clad, and the 8th continues, but when Ritsu and Haumea both use their unique abilities, everyone involved is placed in imminent danger. It’s up to Vulcan and Arthur to turn things around.

As Nataku continues to rampage, Shinra Adolla Links with him, revealing the pressure his parents placed on him to succeed. When the threat Nataku poses comes to a head, his protection as one of the Pillars comes from an unlikely source.

A routine trip to the Baptism Church to bless the 8th’s equipment reveals the crisis of faith that Iris and other Holy Sol Temple clergy are facing. Assault is back and ready to take on Tamaki, who stands in his way of exterminating the 8th.

Maki returns home for a family dinner, where her brother, Takigi, a criminal investigator with the Armed Forces, asks her about her time in the Nether. When Takigi is injured in a White-Clad attack, Maki’s father recalls her to the military.

Company 2 and Company 8 launch a joint, multi-pronged investigation into the Nether, and are met with resistance by the White-Clad. The squad containing Tamaki and Juggernaut faces a particularly deadly new foe named Orochi.

Tamaki struggles to get Juggernaut back to the surface. Takigi and Hinawa find themselves at odds with each other, as well as with a new threat from the White-Clad. Shinra suddenly comes face to face against an old adversary.

Shinra and Arthur continue their battle against Dr. Giovanni, who reveals some new information about Adolla Links. Licht discovers an imminent crisis threatening the Fire Soldiers in the Nether, as well as the Tokyo Empire at large.

Shinra wants to know why he was able to Link with Konro, while Hibana remains suspicious of him. Benimaru invites Shinra and Arthur back to the 7th for more training, and Tamaki, tired of being a burden to others, comes along as well.

Benimaru continues to push Shinra and Arthur to their limits in order to unlock their Hysterical Strength. Captain Huang examines Konro at Hibana’s request, as she tries to uncover the mysteries of those who have been touched by Adolla.
