The vast majority of kajirae are branded, marking them permanently as slaves. Slavers will only rarely sell kajirae that have not yet been branded. In some cities, it is illegal to offer an unbranded slave for public sale. Branding is commonly done by a trained Iron Master as many Owners rarely brand Their own kajirae. In the Landing, branding is often performed by the High Jarl, as he has developed considerable skill, and actually enjoys the ritual. Branding requires a sure hand and experience to properly do it. By recommendation of Merchant Law, there are three standard marking places: left outer thigh, right outer thigh, and lower left abdomen. The most common site is high on the left outer thigh, high enough to be covered by even a brief tunic. Kajirae may be branded anywhere on their body but it is not as common.

Many Goreans prefer a kajirae to be hand branded. Some Slavers use mechanical branding devices but such brands are too uniform. It takes some time to bring an iron to the necessary branding temperature. The iron must also be cleaned and reheated before branding another slave. Cleaning is important for the precision and clarity of the brand. A branding rack is often used to hold a slave's thigh in place to prevent them from moving when the hot iron is applied. This helps prevent a blurred brand. Kajirae are commonly shown the iron before the branding so that they may fully understand its power, its heat and its meaning. Slaves are usually branded for about three Ihn, about four Earth seconds. The kajirae are permitted to scream during the branding. In the Landing, bondmaids are typically branded for 5 ihn.

The most common brand is the "Kef", the first letter of the word "kajira" in cursive script. It is also known as the "staff and fronds" because it resembles a staff with two, upturned frond like curls, joined where they touch the staff on its right. It is usually one and a half to two inches high. The Kef is more floral than the common cursive Kef. The two curls are meant to symbolize femininity and beauty. The upturned curves on the fronds indicate total openness and vulnerability. The staff symbolizes that the femininity is subject to discipline. Male slaves are branded with a large block "Kef", not the cursive letter. There are many other types of brands such as the Dina and the Palm brand. Some Cities have their own special brand as well. Some Merchants make up Their own new brands. There are Collectors who collect girls with exotic brands. In the Landing, the preferred brand for a bondmaid is the Torvie 'belly under the sword' brand.

A small and delicate brand enhances a girl's beauty. It also has definite psychological benefits that instill the idea of slavery on kajirae. It is easy to consider that you are property when you have been permanently marked like livestock. Kajirae will basically only be branded once in their lifetime. A brand simply signifies that you are a slave. It does not always serve to identify your Owner. Thus, there is little reason for an Owner to want to rebrand a girl. Certain penalty brands may be added such as thief or liar to punish a kajirae and mark them as what they truly are.

A kajirae with a brand can still be freed. However, the mark is permanent and there is no method ever mentioned that would remove or alter it. If such a slave is freed and wishes to remain Free, they better ensure that their papers of Manumission are kept handy. Luckily, most brandings can be kept well hidden so Others cannot notice the mark of kajirae. But, if a Man does see that a Free Woman has a brand, he might try to enslave her unless she can prove she was freed.
