The enemies Tanjiro and his friends have to deal with throughout the show are extremely powerful and will give any warrior a run for their money. Some of themost savage characters inDemon Slayerare mentioned below.

8Kokushibo

He might be the Upper Rank One Demon and the strongest member of the Twelve Kizuki, but Kokushibo is actually one of the more reserved demons on this list. He used to be a humanwho learned Moon Breathing, but the jealously he harbored at the natural talent of his brother made him go down a dark part from where there was no coming back.

Kokushibo is yet to be shown in the anime, but it goes without saying that his first appearance is bound to be a blast. He might have a twisted sense of honor about him, but that doesn’t take away from the fact that this demon has done some horrible things to get where he is.

The Former Lower Rank Six demon is a pretty imposing foe with tricky attacks that make any explorer of his mansion die a grisly death. Thankfully, Tanjiro had his wits about him and perfected his combat stance to unleash a devastating attack that ended this demon’s life once and for all.

Given his rank within the higher rank demons, it goes without saying that Kyogai had performed some really savage actions throughout his pitiful life.Tanjiro finally put an end to this demon’s lifeand prevented him from killing anyone else ever again.

6Rui

Tanjiro’s first encounter with a proper Kizuki member comes when he gets into a fight with Rui, a powerful demon who could use spider-like powers to decimate his opposition. The child had a twisted disposition from the get-go, and his transformation into a demon at an early age simply fueled this notion even more.

4Daki

WhileDaki’s headstrong natureis what ultimately proves to be her downfall, it does play a major role in making this character so savage and brutal. In fact, Daki does have a pretty tragic backstory, which is why she developed such a brash personality to tackle problems head-on instead of being meek and passive.

That being said, her heinous actions as a demon still can’t be excused, and viewers can’t wait to see this demon put in her place by the heroes inDemon Slayer’s latest arc. It’s going to be a satisfying moment indeed, especially given how barbaric Daki really is.
