To start off, this is my first review.

*THIS REVIEW MAY CONTAIN SPOILERS so feel free to click away if you did not read this manga*

I would say that the story is quite okay and the vampire and humans fighting each other is a good plot but i have to be completely honest, that i found the family and friends theme quite cheesy and quite tiring. If you are not okay with that kind of theme and you are repulsed by it, i do not recommend this manga.

*THIS SECTION MAY CONTAIN SPOILERS*

I have a problem with the typical shounen protagonist (ya know the hot headed and reckless one), hyakuya yuichirou forcing his values down other people's throats which gets annoying and then insisting on saving Mikaela after finding out that he is alive (and not killing Mika after he injured Guren is confusing to me) and then on the opposite end of spectrum where hyakuya mikaela constantly says humans are terrible and insisting to save hyakuya yui from other humans where i found it to be a quite angsty and unneccessary plot line. This plot could have been focused on the origin of vampires themselves.

Some of the characters quite bland and boring and their friendship with each other is too quick in my opinion. They have doubts which each other and then are suddenly friends (Kimizuki and Hyakuya). I get iffy with that kind of scenario like you don't suddenly trust people with the snap of your fingers. Some of the characters also play on tropes like Sangu Mitsuba (your typical tsundere) and Saotome Yuichi (your sweet supporting protagonist who secretly has dark intentions). It would be better to show how he is more sadistic then he seems but the mangaka chose to go for the tell, don't show route.

However, there are some compelling characters in this story which make things interesting like Shinoa Hiragi, Shinya Hiragi and Krul Tepes.

Also i apologize if it seems that i am criticizing the characters instead of the actual story. Because the characters flaws stand out in this story a lot, so i feel the need to touch on this area.
