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.
I had a dream that you and 
I went for a delightful afternoon stroll.
حلمتُ أنّنا ذهبنا نحن الاثنتان
في تمشية ظهيرةٍ جميلة
Ich habe heute geträumt.
D’ailleurs, j’ai fait un rêve.
Sai, ho sognato che noi due facevamo 
una piacevole passeggiata pomeridiana.
Sonhei que você e eu saíamos
para um delicioso passeio a tarde.
Мне снилось, как мы
мило прогуливались после полудня.
