Vague spoilers beyond this point!
Basically, it starts out as a fantasy series with a lot of potential. Then about 4 or 5 episodes in, it throws in a twist that changed the nature of the series and made me think it had even more potential to go down a dark and unique path. Then around episode 10 or so you realize you're just watching a formulaic locked-room mystery with a fantasy coat of paint. Then, after solving the mystery in the last episode, there's a last-minute twist that completely undermines the solution and renders the whole thing ridiculous, just for the sake of adding in another girl to the MC's harem and providing a limp sequel hook for a second season. Unless you particularly enjoy mystery plots, don't waste your time.
