Yushiro

Yushiro's powers and abilities

Overall Abilities: Yushiro is a demon of unknown strength, although living for a long time under Tamayo, who is herself a deceptively strong demon who could severely weaken Muzan, it is assumed that Yushiro is a competent fighter as well who can make use of Blood Demon Arts. Yushiro for his part, however, is more of a support combatant aiding others with his powers to allow them to discern invisible things or otherwise mask his allies' presence. Most impressively, Yushiro is strong enough to wrestle for command against Muzan over a demon, albeit with the help of the Demon Slayers to interrupt Muzan's concentration.

Body Modification: Through unknown surgical procedures, Yushiro's body has been adapted to live with minimal human blood consumption and no drive to hunt humans. Tamayo stated that Yushiro requires less blood than she does to sustain himself.

Curse Immunity: As a result of being a demon created by Tamayo who severed her link with Muzan, Yushiro is by default not linked to him and as such immune from Muzan's control, preventing the Demon King from exerting any influence over him, such as destroying him remotely or reading his thoughts albeit Muzan was able to partially spread his cells to Yushiro's hand to wrestle Nakime's control from him and to kill him.

Medical Skills: Being Tamayo's aide, Yushiro is also an expert medic being familiar of her special techniques and drugs. After rescuing Zenitsu from falling to his death, he was able to make use of numerous medicine in order to prevent the damage inflicted by Kaigaku's Blood Demon Art to spread further. He was also able to resuscitate a nearly dead Tanjiro to health, allowing the latter to be able to fight again.

Talented Painter: Within the Reiwa Era of Japan, Yushiro became an artist who paints photorealistic pictures of Tamayo on a canvas which have received critical acclaim from all around the world. His paintings are so realistic that some people mistake them for photos.[5]

Blood Demon Art

Yushiro's Blindfold.

Blindfold (目め隱かくし Mekakushi?): Yushiro's Blood Demon Art allows him to create paper talismans which possess the ability to mask or reveal something's presence. By placing these on certain objects of his choosing, he can get rid of their presence. Otherwise, by placing it on someone's forehead, he can enhance their vision by revealing the presence of masked objects.

Yushiro has used this Blood Demon Art to completely hide the entrance to Tamayo's clinic in Asakusa, and used it to create illusory walls to make it less suspicious as well. However, he couldn't mask its existence completely from Yahaba's own Blood Demon Art's tracking ability. He can also render himself invisible using his Blindfold. Yushiro has also used this to reveal Yahaba's hidden arrows and bestow this power to Tanjiro as well. During the Infinity Castle Arc, it seems Yushiro's Blood Demon Art has developed considerably. Not only can he create dozens of his paper talismans at once, but he can use them to completely mask their presence but still see one another, granting them a slight advantage against Muzan. His Blood Demon Art can allow two beings to use their vision in tandem to increase their efficiency in combat, as seen with Obanai Iguro and his pet snake Kaburamaru (鏑かぶら丸まる Kaburamaru?).

Yushiro's paper talismans were also able to link Kiriya and his sisters to the location of the Demon Slayers in real time through the Kasugai Crows that were also wearing the paper talismans on their neck. This allows them to not only see through the paper talismans on the Kasugai Crows, but also issue commands to them. They have used this connection to gain information of battle results, casualties, and the Infinity Castle's constantly changing structure.

Mind Control: During the Infinity Castle Arc, Yushiro displays a new ability of his Blood Demon Art, which allows him to put an individual with his Blindfold under hypnosis and take control of their minds and vision. If used on a demon, he is able to make use of their techniques through them as shown when he used Nakime's Blood Demon Art to bring the Demon Slayers to the surface while the Infinity Castle was collapsing. His control over them is not only mental but also physical, as evidenced by his brief contest with Muzan over Nakime, where both parties controlled her body as they wrestled for command. Yushiro impressively was able to fight Muzan absorbing his cells through Nakime, thus implying Yushiro manipulates his victims on a cellular level. One drawback to this ability is that Yushiro is required to be in proximity of his target to control them.
