Not what I was expecting.

Yuuri is a young boy alone in his mansion following the death of his parents until one day a maid of dark skin, striking pink eyes and modest bust arrives to become his maid known as Lilith, initially suspicious of the beautiful maid and not helped by her naturally teasing nature, Yuuri must work out why Lilith decided to serve him.
This is not what I expected, while they obviously can't go full adult, I found myself feeling a bit bored, Yuuri being innocently honest makes for a running joke that out stays its welcome and suddenly makes this eleven episode run a bit of a strain to view as were spending most of the series repeating the same jokes, Lilith is such a uniquely designed character for an anime that it feels wasted on a safe anime like this, if not for her, you'll forget this very quickly.
Not seen the dub, but as long as Lilith is voiced correctly, should be okay.
Final Verdict: Its pretty boring, Lilith is well done but is stuck in such a boring anime.
