The Goddess has been summoning and reincarnating a broad range of people in order to stop the Hero from destroying the world, but they all seem to have ended in failure. However, all the reincarnations that had been conducted until now were for the purpose of gathering data. With the data she has gathered, she summons the person most likely to stop the Hero.
From now on, she'll conceal her identity 
and live here as your younger sister.
،ستخفي هويّتها من الآن فصاعداً
وتعيش هنا بصفتها أختك الصغيرة
Von nun an wird sie
ihre Identität verbergen
A partir de ahora, ocultará su identidad
y vivirá aquí como tu hermana menor.
A partir de ahora, ocultará su identidad
y vivirá aquí como tu hermana pequeña.
Elle cachera son identité et vivra ici
en tant que ta petite sœur.
D'ora in poi vivrà qui come tua sorella
minore, nascondendo la sua identità.
De agora em diante, ela esconderá sua identidade
e viverá aqui como sua irmã mais nova.
Отныне она будет скрывать свою личность
и станет твоей младшей сестрой.
