 * Poison Nepenthes

Prey

 * Yurina
 * Yuki Ea

Scenario
In this chapter, Daigo, Yurina, and Daigo's childhood friend Ea battle a monster called Poison Nepenthes, which resembles a giant pitcher plant. After the Nepenthes grabs Ea with its tentacles, Yurina attacks the monster, freeing Ea, but gets caught herself. The Nepenthes then drops Yurina into its mouth, swallowing her whole.

With Yurina trapped inside the monster's stomach, unable to fight, Daigo and Ea use the mobile game to bestow Ea with magical powers. With her newfound powers, Ea fights the Nepenthes, but she too is caught by the monster and swallowed. However, using her sword, she splits the Nepenthes open from the inside, freeing herself and Yurina.

 * Lamia

Prey

 * Yuki Ea
 * Yurina

Scenario
In chapter 16, Daigo, Yurina, and Ea are approached by a woman who asks for Ea. The woman then reveals herself to be a monster known as Lamia and ensnares Ea with her tail. Lamia saps Ea's strength by kissing her, after which she pushes Ea into a predatory mouth in her snake bottom and swallows her whole. Lamia attempts to leave, but is stopped by Yurina who wants to get Ea back. Yurina attacks Lamia, but the monster easily brushes it off and then threatens to eat Yurina as well.

In chapter 17, Lamia quickly defeats Yurina by piercing her body with her tail and then sapping her strength. She then feeds Yurina into her body as she had done with Ea. Inside Lamia's stomach, Yurina attempts to free herself and Ea, but several sharp appendages spring forth from Lamia's stomach and pierce Yurina's body, rapidly depleting her strength and digesting her. Before Yurina succumbs, however, Lamia is attacked by Haruka, an ally of Daigo and Yurina, and the blow knocks Yurina out of Lamia's stomach.

In chapters 18 and 19, Ea remains trapped in Lamia's stomach as Haruka battles Lamia, but ultimately fails. Lamia then leaves with Ea still inside her stomach.

In chapter 20, Lamia releases Ea from her stomach as she plans to exploit her ability to summon items from the mobile game

 * Hell Frogger

Prey

 * Honoka

Scenario
After invading the enemy fortress and being separated from her comrades, Honoka encounters Hell Frogger, a small frog-like girl accompanied by a giant frog monster. Honoka battles the two, but quickly finds herself outmatched. After taking severe damage, Honoka is picked up by Hell Frogger who then feeds her into the giant frog's mouth and she is swallowed whole.

A small flower bud then sprouts on Hell Frogger's head and she explains that, once it fully blooms, Honoka will be completely digested. Inside the frog's stomach, Honoka remains completely helpless as her clothes begin to melt. Hell Frogger then strengthens the giant frog by spraying him with water from her water bottle, which accelerates the digestion. The flower then fully blooms, seeming to indicate that Honoka has been digested, but the flower then wilts and the giant frog falls over. Honoka is then released from the giant frog and explains that she slipped salt into Hell Frogger's water bottle, which subsequently weakened them once they sprayed themselves with it. Hell Frogger falls over, defeated, and Honoka takes her leave.

The King Absorber and the two regular Absorbers accompanying it, quickly overwhelm her. After one of the Absorbers sap her of her strength, the King Absorber grabs Haruka, drops her in its mouth, and swallows her.

Inside the King Absorber's stomach, Haruka's clothes quickly dissolve, but she summons a new weapon that she uses to destroy the monster from the inside out, freeing herself from the monster's belly.

Scenario
As Daigo, Yurina and the others finally confront Lamia, they begin to battle her along with several other monster girls. Early in the battle, Daigo is attacked by a monster girl using a puppet that connects his movements to the puppet's own. The monster girl throws the puppet through the air towards Lamia, forcing Daigo to do the same. Daigo then lands directly inside Lamia's "predatory" mouth and she swallows him whole.
