Conference of the Battalion Commanders
In central Tokyo, Raffles III, the emperor of Tokyo, informs his attendants to gather all of the Battalion Commanders of the Special Fire Brigade. Later on at the 8th Special Fire Fighting Church, Shinra queries Akitaru on the reasoning for his and Tamaki's presence at the gathering, and he explains that since he was a witness of the Bug experimentation as well as the White Hoods that killed Rekka, they would be an informative presence there. From behind the door, Arthur peeks his head through, letting everyone know he's no longer lost. On the journey to the gathering, Akitaru mentions that this is the first time since his becoming of Commander that the amassing of all the Commanders has happened. As they arrive, Shinra is astonished to see the Amaterasu, the generator that powers all of Tokyo, for the first time in person. As the 8th walk in, Shinra spots the Commanders of the 3rd, 4th, 6th and 7th, for the first time, as well as the rest of the Commanders. He glances at Benimaru Shinmon, pulling a smile at him, to which he calls Shinra a brat and walks away annoyed. Everybody begins to pray as the emperor walks in, though Benimaru sits relaxed, legs on the row of seats in-front of him. An intense atmosphere is settled, as the emperor begins talking. He finalizes by stating that all of the Special Fire Brigades must treat the preacher as a major threat, and for all of them to investigate and rid of him. Beinmaru interrupts imprudently, to which Gustav confronts him for being so rude, telling him to apologize, but is spoken back to disrespectfully. The 7th Commander then stands up, stating that the 7th Special Fire Brigade will be acting on their own accord as always, and leaves the building with his colleague. As Gustav shouts at the stubborn and young Commander to come back, the emperor tells him to leave him alone. In an unknown location, Joker's Associate speaks to him over a device, asking him if he can hear the gathering. The man on the other end seems to be amused by the emperor's desire to eradicate the preacher.

Raffles looks to Shinra, claiming the boy has Adora Burst, a pure flame that is rare among Third Generations. After explaining what it is, Giovanni suspects that the Preacher is looking for the Adora Burst, and so Shinra should be protected, but Shinra protests to this, claiming he can protect himself, to which Hibana agrees. After the conference ends, Giovanni confronts Hibana as he initially thought she would be on his side as they're both affiliated with Haijima. After stating she treats the 8th specially, she walks always dissatisfied, saying she'll send data on the giant Flame Humans. leaving Giovanni irritated. Later on, Akitaru and Tamaki return from their journey, and Iris questions Shinra's whereabouts as he's not at the Church, to which Akitaru states he'd went to buy some supplies. Shinra is then seen walking through an alley thinking about the Preacher, and is then confronted by Joker, startling him greatly. Shinra prepares for a fight, but Joker tells him to relax, and encourages the boy to keep chasing after the Preacher, as he'll find Shō there too. Soon after, in a dark room lit with multiple candles and filled with people of white hoods, a boy with a katana walks through the middle of them and sits, revealing himself to be Shō Kusakabe, the leader of the Ash Flame Chivalric Order organisation.
