Daiyōkai

A is a very powerful type of yōkai that is much stronger and smarter than common yōkai. Most daiyōkai have long lifespans, possibly even longer than those of normal yōkai. They tend to remain calm in battle even if the situation is dire or their life is threatened. Daiyōkai vary in shape and size, just like normal yōkai. Some have, or are able to transform into, human-like forms, such as Tōga and Sesshōmaru. Others, like Ryūkotsusei, are very large in size and don't at all resemble humans. Though it is not clear whether this applies to all Daiyōkai, it seems that some became feudal rulers over vast territories, commanding lesser demons. They sometimes wage war against other yōkai and humans alike.

During the story, almost all daiyōkai (except Hōsenki, Tōga, Tsukuyomaru) showed a haughty, arrogant, ruthless attitude towards other yōkai and humans, despised them for being weak in their opinion. They also did see themselves as invincible and were quite confident about their own skills and weapons. The only daiyōkai who seemed to have changed their point of view (to a certain degree at least) throughout the plot was Sesshōmaru.
