Rokuro ( (ろく) () Rokuro?) was a member of the Twelve Demon Moons, having held the position of Lower Moon Two.[1]


Rokuro had the appearance of an older man with a stocky build and pale skin that was decorated with black vein-like pattern on down his face, arms and legs. He had long, dark brown hair that he left down, and a short jagged beard around his jawline, as well as golden, cat-like eyes, the kanji for ‘Lower Moon Two’ etched into his left.

He wore what appeared to be a dark cyan version of a typical karate gi.


As with the other Lower Moons, Rokuro both respected and feared Muzan Kibutsuji as his leader. After almost every Lower Moon had been killed by Muzan, Rokuro was visibly scared that the same would happen to him, and resorted to begging his leader for more blood to increase his strength so he wouldn’t die, showing quite a cowardly demeanor. Despite this, however, Rokuro appeared to be very confident in the potential of his abilities as a Demon, since he claimed that if he received just a little more of Muzan's blood he could definitely become a strong fighter worthy of being in the ranks of the Twelve Demon Moons, which showed he had a great resolve and passion for his role.

The Lower Moons gathered

The Lower Moons gathered.

After all of the remaining Lower Moons gather together at the Dimensional Infinity Fortress, Muzan appears before them in his female form. He regards them with annoyance and tells them to lower their heads and squat in front of him. After they all do so, Mukago utters that he's sorry to have to have been ordered to do so, since he didn’t recognise Muzan in that form, to which Muzan angrily asks why he's speaking without permission, telling him to silence himself and not to talk unless directly asked a question. As she cowers in fear at his feet, Muzan goes on to explain the death of Rui, the only Lower Moon who isn't amongst the ones gathered before him, and asks the remaining Demons why they're so weak.[2]

He lectures them about how them being in the ranks of the Twelve Demon Moons isn’t the end, only the beginning of what's to come, and that their sole purpose is to consume blood so they can be of use to him. Muzan says that it's been hundreds of years since the Upper Moons were last replaced, yet the Lower Moons are replaced all the time, to which Kamanue thinks to himself that Muzan can’t just tell them that.[3] Since he can read the minds of those he has shared blood with, Muzan angrily asks Kamanue why they couldn’t be told that, expanding and extending his arm into a tentacle to grab the Lower Moon by his neck and lift him into the air. Kamanue attempts to apologize, but is promptly eaten by Muzan as Rokuro and the rest of the Lower Moons keep their heads lowered in a shocked silence.[4]

Wakuraba killed by Muzan

Wakuraba killed by Muzan.

Next, Wakuraba thinks to himself that he's also going to be killed, so he needs to do more in order to keep his position as a Lower Moon, and, at the same time, Mukago thinks about how he runs every time from the very mention of a Pillar. Muzan repeats aloud both of their thoughts, and a terrified Mukago exclaims that that isn’t true and that he would fight with her life in the line for him. Muzan asks her if he is denying what he was saying, and, as he begins to cry, another bout of Muzan's tentacles crushes him into the ground.[5]

Shocked by this, Wakuraba immediately assumes the worst and decides it would be a wiser choice to flee than stay if he wanted to keep his life. He dashes out of the Dimensional Infinity Fortress at a high speed, and Enmu thinks to himself that that was a stupid move to make since Muzan will kill him either way. This conclusion turns out to be correct, as Wakuraba's head is swiftly chopped off, so fast that it leaves him wondering how he even died in his final few moments.[6]

Rokuro about to be killed by Muzan

As one of the two Lower Moons left alive, Rokuro panics, exclaiming that he can definitely still be useful to Muzan if he just defers his death for a little longer. Muzan asks how he would be useful, how long the deferment would last, and how much power he could wield as he was, and Rokuro explains that if he had more of Muzan's blood, he can adapt it and definitely become a strong fighter worthy of his leader. Muzan angrily tosses Wakuraba's head down next to Enmu and Rokuro, asking Lower Moon Two why he should be given more blood and saying that he should know where he stands. Rokuro tries to protest, but Muzan silences him and says that, since he had attempted to instruct his leader, Rokuro deserved to die.[7]

Abilities and Powers

Demon Abilities

Little is known about Rokuro's strength and abilities as a Demon, but, as he was chosen to be one of the Lower Moons of the Twelve Demon Moons, it can be assumed that he possessed stronger powers than to average Demons and was superior to Kamanue, Rui, Mukago and Wakuraba as he was given a position above them.
