Comments of chapter undefined of Dimensional Descent

I don’t understand how he gets out of this situation, also I feel like he just straight up made the wrong decision in coming here, I can’t understand how leaping from a frying pan only to land into the fire was the safer option to him. Even if he chose to just hide in the outskirts of the demon domain, it would be a way better option, no? He could literally just jump into the segmented cube and then have Anastasia go stealth mode. He has already done this mutiple times under their noses so it’s proven to work. I guess the main worry is the demoness finding him since her dream force is probably too powerful to hide from but I still don’t quite believe it. I feel like this is all just to fulfil a plot point.
