Asakusa arc
After discovering the Special Fire Force Company 8 are visiting the 7th in Asakusa, the White Hoods prepared to attack them and cause disruption like they did two years ago in Asakusa. Unknowingly to the 8th and 7th, Jonah of the White Hoods used his Ignition Ability to fool both brigades and cause a fight between them.

Arrow and Haran were confronted by Shinra and Arthur, and the two teams fought, resulting in Haran choosing to become a Demon Infernal himself. As Shinra and Arthur struggled against such a foe, Benimaru stepped in, and finally defeated him. Arrow and Haran returned to their base to inform their leader of Haran's death, and a "demon within the 8th" acquiring the Adora Burst and Adora Link, with Shō stating that he will go on the attack next time.
