Stigmatas are either natural or artificial resistance which provides the eligible person with resistance against Houkai energy, which allows them to fight zombies and Houkai beasts without getting infected by the source. However, valkyries without natural Houkai resistance since birth are forced to have artificial transplants to protect them from the Houkai but side effects can occur.
Stigmatas are the natural Houkai resistance in a valkyrja's body in the form of a tattoo. Normal human beings without stigmatas are vulnerable to the Houkai, in which the stigmata provides resistance to it. However, only few valkyries have access to their natural stigmata, which makes it hard to fight against the Houkai.
Artificial stigmata transplants are available but it has numerous and potentially dangerous side effects. Without natural resistance since birth, some valkyries are forced to have artificial stigmata to keep themselves temporarily safe. Having constant fights combined with the side effects can make the Houkai invade a valkyrja's body.
If a valkyrja cannot resist the Houkai, they will be burnt out until nothingness or permanently lose all reasoning, which turns them into a dangerous zombie. Lin, a former valkyrja, was burnt out as a result of not resisting the will of the Houkai.
