"Are you sure you're not a Japanese person who simply thinks they are a vampire? Please see a medical professional for delusions of grandeur."
Story: The general idea isn't new, but still entertaining. Long forgotten vampires suddenly rise up and creates a nation of their own in the borders on Japan. Seen this kind 3-4 times before, but still entertaining. However, the problem is that the story ignores almost every thing we need to classify something as a vampire. The author removes almost every unique thing a vampire heroine could be, and instead turns this into a typical high-school story. So let's forget the overly simplified "vampire" part. This is a romance / harem story. We have a twin-tailed tsundere that is physically abusive, a protagonist that's too nice to leave her alone. And as the reader, I just keep thinking about every single harem story I've ever seen/read before. Nothing has changed, this story tried to use vampire romance as bait, but all we got was the regular bullshit we've seen in every other harem story.
As a parody, however, this story stands high and mighty. Ever wonder why a harem protagonist is so popular? Well, this protagonist was blessed/cursed, he is so beautiful that his mother and sister both tries to r*pe him, the harem logic finally makes sense! And everything in the new vampire country is plagiarized from something, even the national anthem is an anime song, which makes it laughable. So while this story fails at the whole "vampire" part, it's surprisingly good from a parody perspective. Though, as a MacGuffin, maybe a vampire kingdom wasn't the best choice... If this was isekai, it would've been a lot more entertaining. Then again, this story is over a decade old, so it's just before the isekai boom we're having today.
Art: The art is good for a rom-com. The girls are cute and the black'n white art looks a bit different than normal, which makes is more memorable. Rough lines with good character designs.
Characters: Unfortunately the characters are a bit weak, for a rom-com. For a parody, they are good. A borderline suicidal friend, a tsundere, and a boy that every (human) girl wants to forcefully mate with. These characters are flawed, annoying, and not very likable. But that is also why they are so entertaining. It's like konosuba, every character is completely fu*ked up, but together they make a fun bunch of people.
Overall. This story is both good and bad. Both boring and entertaining. As a "romantic" comedy, it's bad. As a parody of normal harem stories, it's good. So in the end, it's up to the readers if they want to take this story seriously or not. In my mind, this story is supposed to be a joke to be laughed at, but if it was actually a serious attempt on a good harem series', then, I'm sorry? I guess? Finally, this author has written other works that I've read. They all started as entertaining enough, but eventually became boring and forgettable. Let's hope that this old and outdated "rom-com" was his masterpiece that is finally getting the attention it deserves. After all, the physical release in english is still brand new.
And to quote the suicidal girl from this tale comes these beautiful yet sad words:
" I can't wait for the sweet embrace of death. "
