I'm sorry, but I don't know who the author of 'ao oni novel' is. There may not be a lot of publicly available information about it, or it could be a relatively unknown work.
Well, 'ao oni' could potentially be a character or a concept within the novel. Maybe it tells a story of this ao oni's adventures, its relationships with other characters in the fictional world. It could also explore themes related to good and evil if the oni represents the 'evil' side, or it might be a more complex story where the ao oni has a different nature than what is traditionally expected of an oni.
Tattoos and tattoos hurt, but the degree of pain varied according to the individual's tolerance and the tattoo artist's skills. Tattoos and tattoos were essentially the same. They were both created by piercing the skin with a needle and placing the paint into the skin to form a pattern. Tattoo studios would usually use a special anesthetic for tattoos to reduce the pain. This anesthetic was applied externally and directly on the skin without any side effects. Everyone felt pain differently. Usually, the parts with more nerves would feel more pain, such as fingertips, buttocks, armpits, inner thighs, and inner arms. Therefore, it was impossible to determine whether the tattoo or the tattoo was more painful. It depended on the individual's feelings and the location of the tattoo.
There were some differences between tattoos and tattoos in terms of cleaning. Tattoos required special maintenance and protection measures, while tattoos needed to be cleaned and disinfected regularly, especially after the tattoo was done. Although both required cleaning and maintenance, the cleaning requirements were different for the genders of the two art forms. As for which was easier to remove, the degree of removal of tattoos and tattoos depended on the color of the tattoo and the depth of penetration. Generally speaking, black tattoos were easier to remove, while red, green, yellow, and other colors were more difficult to remove. Using lasers to remove black tattoos usually only required one or two attempts. However, for colored tattoos, even if they were washed off, there might still be some residual color. In general, the effect of tattoo removal varies from individual to individual. For specific situations, it is best to consult a professional tattoo shop or medical institution.
