Summary
The morning after the battle against the White Hood, Company 7 have almost completely repaired the damage to the town.

In the base of Knights of Ashen Flame, the commanding officer is informed of Haran's transformation and death. Additionally, they tell him that an officer in Company 8 for has the Adolla Burst. In response to this, Commander Shō Kusakabe promises to handle the next situation that involves Shinra.

Meanwhile, Benimaru and Akitaru exchange sake cups: forging a bond of brotherhood between Company 7 and Company 8. As a result of the alcohol, Bennimaru begins to smile innocently and uncontrollable. Much to the delight of his underlings and (ironically) Shinra, as he is still irritable and rude despite his facial expression. After being thanked for protecting Benimaru, Shinra thinks to himself about the nature of his Adolla Link, deciding to Hibana to explain it to him.

Returning home, Sister Iris rushes towards her allies and alerts them to the new solider that has joined Company 8 despite Akitaru not requested or approving this. They find Captain Hibana questioning this new officers motives and place in the group. Brushing aside her complaints, Victor Licht salutes his new colleagues and introduces himself as Company 8's scenic officer. Unbeknownst to everyone, this latest addition to the group is a long-standing ally to the criminal Joker.
