What happened to Maria and Mamoru? I know that Maria and Mamoru


   escaped the village and erased their tracks, making it impossible for even their own friends to locate them. The Bakenezumi (I do not know the canon transliteration) even assisted their escape by preparing fake remains for the villagers to find, so as to convince them of Maria and Mamoru's death.


However, the Bakenezumi are later shown to have possession of


   their daughter.


How is this possible? Could it be that Maria and Mamoru


   were captured by Squealer and forced to have a child?


In fact, the ethics committee later commented that


   the remains they found matched entirely to the DNA records of the village. Does that mean that the remains really belonged to Maria and Mamoru, and they were killed after they were deemed to be of no use?


Does the novel explain this? I apologize if i jump to paranoid conclusions, but this possibility sounds too scary.
Although it was not explicitly stated in the Anime. The following sequence of events was strongly implied and was part of Squealer's master plan.


Squealer helps Maria and Mamoru escape. Furthermore, he lets them stay and live with the colony.
Squealer waits for (or sweet-talks) Maria and Mamoru into having a child.
Once the child is born, Squealer (and/or his fellow rats) kills Maria and Mamoru.
They take the child and raise him/her. ("him" in the Novel, "her" in the Anime)
Squealer then takes the bones of Maria and Mamoru and gives them to the ethics committee.


When Squealer says that he will prepare fake remains for the villagers to find and that it will "take some time". He really means the actual remains of Maria and Mamoru and that it will "take some time" for them to have a child.



The sole purpose of this was to get a human child that could be raised into an Akki* and used against humans in Squealer's pursuit of world domination.

*I use Akki for short. But they really aren't. In reality, the children raised by the rats will believe themselves to be rats, thus attack inhibition and death-feedback will apply to rats instead of humans.
