Onihara and his team, who are in Japan, are rebelling against UW and attempting to independently develop a vaccine, and he notes that the bombed-out facility was likely a vaccine laboratory, not a virus laboratory.

Princess Anastasia is known for her eccentricity, but in reality, she is detached and immediately begins the wedding ceremony with Reito. The Principality of Rosania is poor in resources and relies almost entirely on imports. Having lost her parents and siblings, Anastasia is burdened with a heavy responsibility. Reito promises to help Anastasia's parents and siblings, who remain in cryosleep, and Anastasia introduces him to a certain person: Ragini Singh, a leading expert in virus research. Upon meeting her, Reito learns that in order to develop a vaccine, virus crystals must be injected into Reito's body, that he will likely die, and that sexual intercourse will be necessary to activate his hormones.
World's End Harem Volume 11 Spoilers
Reito develops close relationships with each of the women, but Erika herself has been excluded from mating candidates. He learns the reason for this: Erika has been administering some kind of drug to herself.

The medication she was given was intended to suppress the symptoms of the disease.
Volume 11 Spoiler Part 2
Suou Miku, who closely resembles Erika, is actually a clone of Erika, created to replace Erika, who is unable to bear children.

It's a potentially fatal endeavor: injecting virus crystals into the body.
World's End Harem Volume 12 Spoilers
After being injected with a high concentration of virus, Reito was on the brink of death. Even with Reito's strong resistance, it was only a matter of time before he met his end. Furthermore, propaganda was spread around the world claiming that the Principality of Rosania had kidnapped Reito through UW's operations and was planning to inject him with a high concentration of virus and kill him. However, thanks to the will of Erika and the others, Reito overcomes the virus's power and completes a vaccine. The completed vaccine is administered to the Grand Duke of Rosania, demonstrating its effectiveness. Meanwhile, Chloe, the mastermind behind it all, claims to have already taken action regarding the completed vaccine. The immediate issue is whether the baby boy he conceived with Hino Kyoji is resistant to the virus.

While Karen was supposed to be working in cooperation with Chloe, she actually protected Hanyu Yuuki from Chloe and her team, and was not completely aligned with Chloe. Yuuki was pregnant with Shota's child, and the baby was a boy resistant to the virus, so she was evacuated, which was the reason for her disappearance.

However, Shota Doi, Karen Ueda, Zen Kinebuchi, and members of Izanami appear before them. They rescue Reito and his friends, but Kyoji is not. The video of Chloe and her allies' atrocities, filmed by Karen, is exposed to the world. UW withdraws from Japan, and anti-UW riots break out across the country.
