Dhampir

The Dhampir (吸血種, ダンピール), ranked twelve out of sixteen Exceed, live by extracting soul essence from bodily fluids such as blood or sweat. While all body fluids can be used to continue their life, they can only increase their power and grow with the consumption of blood. However, due to the implementation of the Ten Pledges, they have to let victims to agree upon before they can obtain blood from them.

It is revealed in volume 4 that the Dhampir have both males and females within their race, they can only mature to adult hood by consuming the blood and mixing their soul essence with another races soul. 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.

In the light novel Volume 4, 『     』, with Izuna and Jibril found Plum, a Dhampir girl at a critical time on the verge of dying of starvation. This girl asked them to give her their Soul Essence. Jibril informs them that 'many bodily fluids contain varying amounts of soul essence'. Shiro helps the girl with the order for her to lick Shiro's foot to consume her sweat. Plum, the Dhampir girl, states that she likes the taste of Shiro's sweat. Jibril says it's because Shiro has a tough, strong, extremely rare, unique and noble soul that any common person who searches the entire world for such a presence will still never meet. After being saved by Queen of Imanity, Plum asked them to help her race.

Sora presumes after the information gained from Jibril that the Dhampir are a form of succubi and not pure vampires as they are capable of feeding on soul essence from bodily fluids other than blood, Although the levels of soul essence are less in other bodily fluids compared to blood with the semen of men containing the highest amount and sweat containing the least.

Strengths
Dhampirs have the capability to use magic with their strongest type being cognitive manipulation (ability to manipulate perception of others and themselves). However, the strength of their spells depend on the species from which they gathered soul essence from (preferably blood considering the high concentration of soul essence in it). A higher affinity species' soul essence results in stronger magical abilties. According to volume 4, if a Dhampir acquired Elven blood, her/his powers would make for a very powerful assassin. However, Dhampirs can't acquire soul essence beyond the seventh ranked elves as the quality and concentration of any soul essence above the elves would result in the Dhampirs evaporating.

Weaknesses
Sunlight is considered lethal to Dhampirs, similar to vampires. As a result, Dhampirs are most active at night or live in places hidden from the sun's rays such as Oceando.

In worst case scenarios the Dhampir shield themselves from the sun's rays using magic but this usually requires a large constant supply of energy to maintain (which is rather difficult considering the pledges limit their options of attaining soul essence from people for said energy).

Therefore Dhampirs seek shaded areas in order to lessen the amount of sunlight thereby requiring less energy to maintain the spell.

In addition, Dhampirs can also spread this sunlight lethality to their victims.

If bitten, Dhampirs are able to gather soul essence from the victim via the victim's blood. However, this also results in mixing some of the Dhampir's soul with the victim's leaving the victim with a mixed soul. Consequently, this creates the lethal susceptibility to sunlight within the victim.

History
They are currently living in mutualistic servitude to the Seirens of Oceando after a bet for their own survival using their race piece.

The game ended in a draw, The seirens bet that the dhampir males would sustain the seirens for reproduction purposes while the dhampir bet to feed on the seirens, The bet was made in this manner due to the infrequent contact of the seirens with direct sunlight.

The bet entailed that the males of the dhampir would regularly consume seiren blood for sustenance and maturation while allowing the queen of the seirens to consume their soul essence so she may reproduce killing the male in the process.

The females of the dhampir have limited blood feeding till a young age, elder females must 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, they also consume other bodily fluids for sustenance often resulting in H-games with males of other races.
