After becoming the strongest in the world before she even knew it, Azusa entered into a new lifestyle with her first pupil, Laika the dragon, and discovered fun and enjoyment in it that she hadn't known before. But then, one day, a young girl calling Azusa her "mama" shows up and proclaims that her younger sister wants to kill Azusa. But Azusa has no memory of giving birth to these two girls, or of becoming a mother at all...
The two of us are made up of the 
souls of the slimes that you killed.
نحن الاثنتان مصنوعتان 
.من أرواح الهُلاميّات الّتي قتلتِها
Also das ist so: Wir zwei sind aus den Seelen
der Schleime entstanden, die du getötet hast.
Nosotras nacimos de las almas
de los slimes a los que mataste.
Nosotras nacimos de las almas
de los slimes a los que mataste.
En fait, ma sœur et moi,
Noi due siamo nate dalle anime degli slime che hai ucciso.
Nós duas nascemos das almas
dos slimes que você matou.
Вообще-то мы состоим
из душ слизи, что ты убивала.
