The town is rebuilding in the wake of the demon's attack, which means there's just one more thing for Rein to do...
I, too, have always desired 
a charming little sister!
!أنا أيضاً لطالما رغبتُ أختاً صغرى جذّابة
Sora wollte schon immer
eine süße kleine Schwester haben!
Anche Sora ha sempre voluto
una sorellina piccina e adorabile!
Eu sempre quis ter uma pequena
e adorável irmãzinha!
Я тоже всегда мечтала
о милой младшей сестрёнке.
