Servamp is a manga series by Strike Tanaka that is published in Comic GENE. The chapters are released monthly and are still first presented in the Comic GENE. The first four chapters in Comic GENE differ (in some texts and pictures) from those printed in the manga. For example, we could see Jejes face in the original version but it cannot be seen in the manga. We also got hints about Tsubaki that were not shown in the manga.
It's not a classic vampire story, it's genres are: comedy, shonen and mystery. In Japan there are 10 volumes now - and still continuing. The English series has 9 volumes by now, with the tenth to be released soon, and the German translation will has 8 volumes as of march 2016.
Servamp was serialized in KADOKAWA Media Factory's shojo magazine since 2011. In March 2015, Seven Seas Entertainment licensed the series in North America.
