So the title is a complete lie, I felt betrayed and disappointed. 0/10
With that out of the way, the oneshot was pretty cool. If only it could achieve greatness by pacing itself a bit better. Sadly it had the usual oneshot issue of jumping too far ahead in a span of a page.
The first chapter of the serialization looks... Promising. It has a different approach to things. Clearly, the vampirism rules were changed since she was bitten but weren't outright changed. Unless the original had the same rule(s) and I just missed that. With so many characters (since I assume the ghost maids will be characters) around it's guaranteed to turn hectic and hopefully fun. The first two pages gave me a feeling like I was about to read a manhua (or however you spell it). Something about the way it was colored.
I'll nitpick and say that Matilda claimed that this was the only opportunity she had for work and when given 3 simple rules she immediately broke them. Clearly, she went full out on her curiosity disadvantage or just failed a normal roll.
