Complete | chrono nanae | 2000 released
Very in depth manga . has an anime so go watch it after you read it <3 The plot is the strongest aspect of the manga , not centered around yaoi or any gay fanservice . There is a lot of implied homosexuality but the plot is the biggest factor . It revolves around vampires and mystery solvings . There are very few sexual panels and there is no explicit sex scene . Action packed
