This is such a strange story atmosphere wise. There's no tension whatsoever. I reckon it's partially because the MC has no desire for revenge, or in fact a desire to do anything at all, apart from living to see the next day. The demon queen seemingly is only interested in running a single dungeon with minimal crew. The adventurers, despite being the ones who betrayed Licht, are half-assed and couldn't put up any sort of a fight. In other words, I don't feel anything when reading the chapters.
