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...
I will kill you so that 
all slimes can rest in peace.
.سأقتلك ليستطيع كلّ الهُلاميّات الرّقود بسلام
Ich werde dich umbringen,
damit die Schleime in Frieden ruhen können.
Te mataré para honrar a los slimes.
Te mataré para honrar a los slimes.
Je dois te tuer
pour venger les âmes des slimes.
Ti ucciderò, così tutti quegli slime 
potranno riposare in pace.
Eu te matarei para que todos os slimes
possam descansar em paz.
Я убью тебя, и убитые
обретут покой.
