Ultimate Skill

Ultimate Skills are evolved skills that are nearly impossible to obtain. Any beings (human, demi-human, monster, demon) can obtain them.

The specific requirements to obtain an Ultimate skill are quite vague. However, it seems that those of very high ability are able to develop them. The majority of Ultimate skill users are quite old (hundreds of years old). The younger Ultimate skill users developed them once becoming a True Demon Lord.

Ultimate skills are able to be bestowed upon by one's master, but in a much weaker form.
