In the future, individual districts have become isolated habitats called "clusters." Equa lives as a student in one such cluster, the university city of Ochanomizu, but she is actually an "extractor" who takes requests from people desperate to flee to other clusters. Shockingly, her latest client is a teacher at her school.
This young lady's a demihuman,
 and a slime at that.
،هذه الفتاة نصف بشريّة
وحمأة فوق ذلك
stellte ich fest, dass sie ein Herdenmensch ist.
Und dann auch noch ein Slime.
Eres una persona cúmulo. Un limo.
Eres una persona cúmulo. Un limo.
j’ai vu qu’elle n’était pas humaine,
c’est une slime.
Questa signorina è una semiumana, 
uno slime per giunta.
Esta jovem é uma semi-humana,
e uma slime, por sinal.
Она получеловек,
да ещё и слизь.
