We meet one of Misumi Makoto's classmates back on earth, who also has a curious encounter with a certain goddess who presides over a certain isekai. She and one other are sent there as heroes to help the hyumans defeat the demons.
The world I protect is currently under 
unprecedented threat from evil demons.
العالم الذي أحميه يواجه حاليًا خطرًا
.غير مسبوق من الشياطين الأشرار
Die Welt, die ich beschütze,
Le monde sous ma protection
Il mondo sotto la mia protezione
O mundo que protejo está sob ameaça
sem precedentes de demônios malignos.
Но миру, что находится под моим
покровительством, угрожают злые демоны.
