The consequence of this act would infect the victims with a disease making the victim sensitive to direct sunlight to the point where the victim will die from prolonged exposure.

There is currently only one young Male left of the Dhampir race, meaning that as a race, when considering the Doomsday clock scenario, they are only 5 seconds away from extiction as mentioned by Sora.

They are currently living in mutualistic servitude to the Seirens of Oceando after a bet for their own survival using their race piece ended in a draw with the seirens betting that the males of the dhampir will sustain the seirens for reproduction purposes and the dhampir betting for access to feeding on the seirens as the seirens mainly live under water and so are not affected by direct sunlight often. The males of their race will regularly consume seiren blood for sustenance and to mature while allowing the queen of the seirens to consume their blood and soul essence so she may reproduce. The females have limited blood feeding till a young age at which they have to venture into the outer world to find males with which to consume their blood to allow them to Mature to adult hood so they may reproduce and to consume other bodily fluids for sustenance often resulting in H-games with males of other races.
