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.
Now I can die without any regrets.
والآن يمكنني أن أموت بلا أي حسرة
Nun kann ich ohne Sorgen sterben.
Ahora podré morir en paz.
Ahora podré morir en paz.
Je peux enfin mourir en paix.
Ora posso morire senza rimpianti.
Agora posso partir
sem arrependimentos...
Теперь можно умереть 
без всяких сожалений.
