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.
I quit. I figured I'd give the 
Hero Academy a shot, too.
استقلت. ارتأيتُ أنّي سأجرّب أكاديميّة البطل أيضاً
Hab gekündigt.
J’ai arrêté.
L'ho lasciato. Ho deciso di provare
 anch'io ad entrare all'Accademia degli Eroi.
Eu larguei. Pensei em tentar entrar
na Academia de Heróis.
Я ушла. Решила тоже попробовать 
поступить в академию.
