In my opinion the anime is somewhat a good show, but the men are really inconsiderate to the Yui (protagonist).I think the thing that makes people like the show is the art,and how so detailed the men were drawn. I don't exactly LOVE the anime but just to let you know, THERE ARE LOTS OF AWKWARD MOMENTS,like really the men are always saying how her blood is so sweet. One of the men is always CLIMBING ON HER BED it's just weird. OVERALL if you like the show I don't mind,and I like the show to but the thing is it's pretty close to s****l harassment, okay I hope understand what I mean watch the show and enjoy the artwork, and the voice acting.
And be safe and have a great day !
