As their scheme to lure out "D" continues, Kimihito takes Papi and Suu to the forest for a picnic, accompanied by Zombina.
However, while musing over large amount of rubbish present in the area the group is attacked by a mysterious Kaiju. While Papi and Kimihito are captured by the Kaiju, Suu falls into a tank of experimental chemicals.
As the Kaiju is revealed to be a Dryad named Kii, who had previous relations with Papi and had grown to such colossal size due to the garbage in the area, Suu returns having also grown to colossal size and a battle between the two kaiju beings begins; with the battle ending after the duo suck out the experimental chemicals from each others' bodies.

As Smith arrives to assess the situation, she allows Kii to stay in the forest and enacts a clean-up order on the forest to better improve the environment for humans and liminals alike. However, it is also revealed that "D" was not the Dryad Kii.
