Rentaro encounters the smartest student in school, Eiai Nano, and it turns out she's a soulmate, too! However, her extreme rationality leads him to question whether they really are meant for each other.
In this world, anything that doesn't improve 
your future prospects is meaningless.
في هذا العالم، أيّ شيء لا يُحسِّن
فُرصك المستقبليّة لا جدوى منه
Einzig, was deine Zukunftsaussichten
verbessert, ist von Bedeutung.
En este mundo, lo que no mejora
tu futuro no tiene sentido.
En este mundo, lo que no mejora
tu futuro no tiene sentido.
Dans ce monde, est dénué d’intérêt
Al di fuori di ciò che può migliorare
il proprio futuro,
Neste mundo, qualquer coisa que não melhore
suas perspectivas futuras não tem sentido.
На свете нет ничего важнее,
чем борьба за своё будущее.
