It kinda does have an explanation, do you want spoilers?
Yeah, I actually read the novel. But I don't remember this part.

Because he is a superior being and the effects of that world only affect him for one day
Also because he came to that world to witness how the protagonist becomes a god
He was brought there by the God of light to kill the protagonist, so his memories are intact because if they were to be reset he wouldn't be able to carry out his mission. Although he dosent know who or why he was brought into their world yet. He'll find out towards the later parts of the novel/manga.
Du ze has restoration, right? His body and objects he had with him goes back to the condition of when he first arrived. Shouldn't this include his brain too? Like his memory resets? Why does his memory not reset though, does this have an explanation?
