Basically A vampire finds out the perfect meal in the night,cute bored boy,walking alone in the streets. But the only sad point,the vampire is allergic to blood. Uh,...allergic to human blood? I cant see sense at all but well... I have actually read all the chapters - 13 in total The raw manga of course. The manga is really amazing ,a lot of good art and have a realy fair end.If you have read only the first chapter it doesnt make sense at all,but after the first chapter the plot changes completely,for example,not a spoiler at all but more vampire appears...
It is a a pain about not having all the chapters translated,I wonder why,because Shimotsuki Kairi have so good mangas,...
The main characters appear to be really interesting,really good art and a good point,vampire plus human! This is always an intersting plot to be made,PLUS yaoi~~~

Overall

About 8-9,the plot didnt got my emotions at all but Izanai s one of the rarest types of Yaoi manga where I can find good story plus vampires .
