[VampireXReader] The Annual Festival for your country is in a special twist this year. Not only is it the 1000th year since your country was established but also the day gateways of other planes open to allow other beings into this world. Everyone believed it was a myth, including yourself. However it's when people start to go missing, wake up in hospitals with very low blood and have no recollection of what happened when you start to get suspicious. Was it really just a myth about old beliefs? Or is it something much more dangerous?
