Siren

The Seiren or Mermaids (海棲種, セーレーン) are the fifteenth ranked race of the Exceed.

They are currently living in mutualistic Dominance to the Dhampir in 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 and so are mainly not affected by the vampiric disease.

The Seiren as a race are at the greatest disadvantage as they live purely under the ocean within their city and rarely venture to the surface. Their race is also solely comprised of females with one Queen acting as the primary source of children for their race (for political reasons) although all Seiren are capable of reproducing with males from any race.

The Seirens, before the enactment of the 10 oaths, would abduct males from any race and forcefully reproduce with them by consuming their blood and soul essence, Due to the amount of soul essence required the male dies in the process.

The Seirens are considered to be stupid by most races; according to Plum and Jibril, Seirens only know to play and mate and are very carefree, even at the prospect of their race going extinct. They don't excel in any particular magic other than the Seduction Magic, as their bodies are filled with Water Elementals that attracts the Elementals in the bodies of the other races.
