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.
"Hidden dungeon only I can enter!
!ديماس خفيّ لا يستطيع دخوله سواي
Das versteckte Dungeon,
das nur ich betreten kann!
¡Mazmorra oculta
a la que solo yo puedo entrar,
¡Mazmorra oculta
a la que solo yo puedo entrar,
Donjon caché
où moi seul peux entrer,
"Dungeon nascosto in cui solo io posso entrare!
"Masmorra oculta em que
só eu posso entrar!
«Подземелье, куда лишь мне есть ход!
