Can anyone please help me find the title of the manga I've read (╥﹏╥)
It's about the mc having absolutely no presence. I think it was a dungeon type manga. The dungeon spawn near his home? And then he raids it I guess.....
He also met this other guy and his party who he raids a dungeon with.
I don't know •  ‿ ,•
Pls help, I just got the urge to read it again and I can't remember the title ಥ_ಥ
Also, he's wearing a mask when he raids
