Fans from community forums have noted several changes from the original source material:

: It is revealed that Kotori was originally human but gained Spirit powers five years prior during a mysterious fire. She is currently kept in a containment room as her Spirit side threatens to consume her.

: Shido visits Origami Tobiichi in the hospital. She reveals her parents were killed in the fire five years ago by the Flame Spirit, swearing a blood oath to kill Kotori, unaware of her true identity.

The episode shifts from high-stakes combat to emotional character building, dealing with the fallout of the previous rooftop battle.
