However, she didn't account for the fact that the island is populated with gigantic killer insects. Her knowledge of butterflies, wasps, and more may be the only thing that will help any of her classmates survive to be rescued. Note: Bundled with manga's 6th volume.

One summer vacation, Ruka meets two boys, "Umi" and "Sora," whose upbringing contains strange and wonderful secrets.

Based on a series of Chiikawa comics posted on X by Nagano from March to November 2023, known as the "Siren Arc" . One day, while Chiikawa and Hachiware were relaxing in the square, Usagi suddenly appeared with a flyer stuck to its face. When Hachiware checked the flyer, it was an invitation reading “Special Invitation to a Special Island.” Lured by promises like “Get 100x rewards for simple island quests!” and “Limited-edition island ramen, exclusive sweets—sweet and spicy treats all practically free!”, Chiikawa and the others decided to go on the island retreat. Boarding the ship alongside Rakko, who was suspicious of the flyer's contents, the group landed on the island... only to find something waiting for them there...!?

The nightmare that wiped out two thirds of the human race thirty years ago wasn't caused by germs. It was bugs on an entirely different kind of scale: bizarre insects that mutate their victims into half-human creatures that rapidly evolve into rampaging giant monsters! Yet, as unstoppable as the monstrous insects seemed, humanity is as hard to kill as cockroaches, and exterminators like Kidou now spend their lives stalking and killing the creatures called Cagasters. As the brief still-partially human phase is the best time to strike, however, exterminators soon learn to distance themselves, socially and emotionally, from normal people. But when Kidou finds himself suddenly tasked with returning a young survivor to her mother, he starts to realize that his emotions and humanity may not be buried as deeply as he believed!
