R-18 [ ]
Definition:
To be used when the content of the story is suitable only for individuals who are 18 or older. This may be due to the story having sexual or violent themes repeatedly. Note that it can ONLY be used for a JP or KR* novel. For others the Adult genre will suffice. * In South Korea, a child is counted as 1 year old the moment they are born. This tag is analogous to the Korean R-19 tag.
