Siren

The Seiren or Mermaids (海棲種, セーレーン) are the fifteenth ranked race of the Exceed. The current representative of the Seirens is their empress Laira who is currently in cold sleep for around 800 years.

They are currently living in mutualistic dominance to the Dhampir in Oceando after the Seirens won the game for mutualistic benefits 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 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. Complying to the ranking of the exceed, 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.

Strengths
Although unable to control magic, Seirens do have the ability to control the water elementals within their bodies. This allows them to generate an attractive force between the water elementals of their bodies with the elementals in other life forms similar to seduction magic. This control also allows them to enter cold sleep in which they can sleep for centuries on end.

Weaknesses
The Seirens race are believed by the other races for being the most stupid race of the Exceed. However, it is possible it could also be a ploy as Laira's game was revealed to be an elaborate trap that even accounted for Plum's betrayal.

The Seiren as a race are at a great 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.

History
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. However, due to the amount of soul essence required, the male dies in the process.
