Not sure about demihuman design, she looks too cartoonish and out-of-place compared to the rest. There is also an ogre that looks very similar to Shion from “Slime” and turns into child as if Shinobu from “Bakemonogatari”.
Character building is bad here, world building seems to be even worse, possibly because of the pacing. Sally freezing before 1st ogre should have been the end of 1st episode to provide more time to explore the world and characters, even if the initial pacing throughout the episode was slower, than the rest of the series going forward.
There were a few good moments closer to the end, so I will give 2nd episode a shot, but I predict it to be similarly mediocre.
