Just like any other demon, Yushiro was once human too. He was under the care of Tamayo while she was a medical practitioner. He was frail and fighting a deadly disease when Tamayo made him choose between dying and becoming a demon.
Yushiro chose to become a demon and became the bodyguard of Tamayo. He had always expressed his adoration for her since then. He also acts as her bodyguard.
Yushiro first met Tanjiro when the latter had to venture to Asakusa, Tokyo to track down a demon disturbance in the area. Being a village boy, the big city of Tokyo is something new to him. While in the middle of the crowd, he notices a familiar scent.
As he rushed to the crowded streets, Muzan was there masquerading as a human with his family. Muzan escaped from Tanjiro by transforming on human into a demon. With all this commotion, Tamayo and Yushiro noticed Tanjiro.
After the situation had calmed down, they brought Tanjiro to their secret house. Yushiro was the one who leads Tanjiro to the clinic of Tamayo. Tamayo, a demon Doctor, was treating her patients. Yushiro, her assistant is helping her. They had been planning to eliminate Muzan for a long time. Tanjiro asks Tamayo if she feels uncomfortable treating humans and Yushiro hits him.
Tamayo reprimanded Yushiro about his attitude. Tamayo told Tanjiro that she was the one who turned Yushiro into a demon. Tanjiro upon hearing this asked Tamayo her age. Yushiro hit Tanjiro again and was scolded severely by Tamayo
Muzan on the other hand, remembers a demon slayer wearing hanafuda earrings who tried to eliminate him from the past. Muzan sent two of his followers to kill the demon slayer who wears Hanafuda earrings.
He sent two of his followers, Susamaru and Yahaba to bring him the head of Tanjiro. Tamayo, Yushiro, Tanjiro, and Nezuko were discussing creating a cure for demons by studying the blood of Nezuko and other demons that are close to Muzan.
While the four are discussing, suddenly, two demons claiming to be part of the twelve Kizuki arrived. It was Yushiro who first notice it. A ball came flying in through the roof and his head fell off. While Yushiro was regrowing his head, Tamayo was holding his body.
Tanjiro went on the fight the Arrow Demon, Yahaba. Yushiro and Nezuko went on to fight the Temari Demon, Susamaru. Tanjiro combined Water Breathing styles and was able to defeat Yahaba but he got extremely exhausted. Yushiro and Nezuko were able to hold off Susamaru. Tamayo had to use a spell that triggers the curse inside the head of Susamaru and he dies.
During the battle at the Infinity Castle, Yushiro was able to control the Upper Moon 4. He used a talisman to cover her eyes and drilled his finger into her skull. He was able to control Nakime and the Infinity Castle.
He shifted the rooms of the castle to force Muzan and the Demon Slayers outside of the castle so Muzan would be exposed to sunlight. During the fight with Muzan, Yushiro used his blindfold so those who had talismans on them would be invisible and could freely attack Muzan.
Muzan realized that the reason why the demon slayers are not visible is because of the assistance of Tamayo. Muzan started lashing out and Zenitsu, Inosuke, and Kanao were the first ones who were exposed.
Muzan eventually lost when he was exposed to sunlight After the death of Muzan, Yushiro was the only demon that was left alive. He then spent his days painting an unknown woman.
Yushiro is a short man that gives him the appearance of a small boy. He has pale skin and lavender purple eyes. His hair is short and straight. It has colors that fades from dull and light green, and black. Yushiro wears a button-up collared shirt under an all-white haori and dark blue Seigo-Sendeheira styled hakama pants.
Yushiro looks down on everyone around him. It is evident that he has a short temper and an arrogant attitude. He has a scowl on his face and rarely smiles unless he is talking about how he admires and adores Tamayo. When he spends his time with Tamayo, he hates everyone who interrupts his time with her.
He hates people who get close to Tamayo, insult her, or express just a little admiration of her. He feels insulted being generalized with other demons. When Tanjiro said that all demons are bloodthirsty, he feel insulted about this and asked if all demons are like that.
The strength of Yushiro was never displayed in the series. Instead, his keen intellect and strategies are the one that is evident. Yushiro could not be controlled by Muzan. He was created by Tamayo who cannot be controlled by Muzan so Yushiro cannot be controlled as well.
When the Demon Slayers were interrupting Muzan and could not concentrate on controlling other demons, Yushiro would control the demons.
Yushiro has his body altered through a surgical procedure so he would need minimal human blood consumption and he does not possess a drive to hunt humans. Being with Tamayo and working as her assistant and bodyguard, Yushiro had learned medical skills from her.
His blood demon art is called blindfold where he can easily hide living and non-living things. He was able to hide the entrance to the clinic of Tamayo as well as the people inside it.
He also used his Blood Demon Art during the Infinity Castle Arc in order to hide the presence of Demon Slayer from Muzan. During the battle, he also used mind control in order to control demons. He wrestled with Muzan who can control the demons.
While the demon slayers were destructing Muzan, and slowly losing control of the demons, Yushiro took advantage of this and fully controlled them. When the battle was over, one of the special skills of Yushiro, which is painting was shown to the world when he became a famous painter.
