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.

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.

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.

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.
