  Witches:

  Since the witch hunts of hundreds of years ago, there are only 22 witches left in the world. (There is a possibility that there are undiscovered witches as well). The witches were deemed potentially dangerous for the world, so there is currently an organization monitoring them.

  When a witch reaches puberty, their witch abilities are awakened. The powers of witches are extremely dangerous, so they must be kept under control. They can use magic such as fire, water, wind, and earth, posing a great danger to humans who cannot use magic. However, even with restrictions to reduce their magical powers, they can still use simple spells. Besides immortality, they are not much different from ordinary people.

  Methods of control: (varies for each witch)

  1) Regur injections of a potion into the witches' uterus (once a month). Depending on the situation, injections may be given more than once a month.

  2) Injection method: a man ingests a capsule with the potion, which causes his penis to become strong and rge after a certain period of time, entering an excited state. The potion mixed with semen is injected into the witches' uterus through ejacution.

  3) Since the potion may fail, multiple injections into the witch's uterus may be necessary.

  Side effects of the potion:

  Men feel a strong urge to ejacute and if they do not ejacute within a certain period of time, there is a risk of death (there have been cases in the past).

  When witches are being injected, they feel a strong sense of disgust and weakness, temporarily unable to resist. To smoothly inject the potion, it is recommended to give witches an aphrodisiac before using the potion. (The degree of resistance varies for each individual)

  Regarding the nature of witches: (individual differences exist)

  Witches receive curses and become immortal. The growth of their bodies stops. Some witches stopped growing at the age of 9, while others stopped at 35. When their first menstruation comes, their powers bloom. When this happens, their appearance changes and the colors of certain parts of their bodies change. It is common for their hair and eye colors to change.

  About the death of witches:

  During the witch hunts of old, there was a definitive way to kill witches. However, the documents detailing this method have been lost, so it is something we may never know.

  Regarding pregnancies of witches:

  Witches have a very difficult time getting pregnant. There is a case of a certain witch who has been ejacuted into by over a thousand men, yet she has not become pregnant. While individual differences are a possibility, according to the records of monitoring organizations, only two witches have been recorded as being pregnant.

  These two were recorded as the "Miracles of the Witches."

  Witches undergo regur physical examinations at designated hospitals by the organization. Generally, their menstrual and reproductive functions are completely normal, without any diseases such as infertility. Their ovution functions are also normal.
