Noir is the 3rd son of a poor noble and his job position is taken away by a more powerful noble. He also sadly lacks enough skills to attend the Hero Academy. He tries to find a way to be able to use his skill [Great Sage] better and stumbles across a hidden dungeon.
And so, I safely passed the exam 
for the Hero Academy.
وهكذا، نجحتُ في امتحان أكاديميّة البطل
Und so bestand ich ohne Probleme
die Aufnahmeprüfung der Heldenakademie.
Y así, aprobé el examen
de ingreso sano y salvo.
