Scattered thoughts:
An accurate sentence I said out loud while watching: "Come on dude, don't let them tentacle rape your fake girlfriend."
Plot and pacing are all over the place, although this is more or less faithful to the source material.
Main antagonist is massively annoying and flat as a piece of paper and all the relationship drama in the show is just bullshit.
Not a single plot thread is resolved, nothing but cliffhangers, although the twist at the end would have potential, if there were a sequel.
Not too well animated or drawn, not especially bad, non-offensive, literally just "an anime".
