How was Yukio at the beginning of season 1?

Yukio portrays himself as a kind and reserved younger brother

At the beginning of blue ghostOkumura Yukio is portrayed as Rin's estranged younger twin brother, the son of Satan.

However, Yukio always keeps his face around his older brother, not wanting to give him any information because he wants to keep Rin away from the demons. Consequently, this is the reason why Satan's Blue Flames are hereditary. After learning to be an exorcist under Father Fujimoto's tutelage, Yukio continued to keep Rin in the dark about his heritage, playing the role of a worried younger brother, as Rin always got into trouble before Father Fujimoto's death.

However, this was just a means for Yukio to hide his true feelings about his heritage. Of course, Yukio cares for his older brother and will go to great lengths to protect him. However, Yukio has always felt inferior to Rin. When Yukio and Rin were young, the neighborhood kids would often bully Yukio, and thus, Rin would run to his rescue. This was probably the beginning of Yukio's inferiority complex, as he was the younger and weaker brother at the time.

However, Yukio slowly begins to change as he learns about demons and ghosts. At that time, he wanted to hold his brother, because he always felt weak. In season 1, Yukio revealed that he became an exorcist to protect the others and Rin because he no longer wanted to live in darkness.

Since Rin is unaware of his heritage, Yukio constantly interacts with him under the hood, without giving away his true intentions and feelings. Overall, Yukio essentially became Rin's older brother in this instance, as Rin often gets into trouble. Since Rin and Yukio no longer have a family, Yukio generally looks after Rin and establishes some authority over him, not only as a mentor in exorcisms, but also as a sibling. However, Yukio's true feelings towards his older brother were yet to be revealed at this time.

Yukio eventually lets his insecurities get the better of him as he seeks more power

Throughout the events of blue ghostYukio has true intentions and feelings; However, Shimei and Rin, who are close to Yukio, are always able to tell that something is wrong. While Yukio's character has always been professional and reserved for cram school, Yukio has been shown to have a short temper.

As mentioned, Yukio has an inferiority complex towards his brother and people stronger than him. Because of this, Yukio feels that he must always work hard and train to prove himself. In addition to this inferiority complex, Yukio has always felt like he was in competition with his older brother. Yukio was under the impression that he had not inherited the same Blue Flames from his father, the devil, and was under the impression that he was a normal human who was born with mashou, so he could see demons.

Although Yukio has always cared for his brother, he also envied him. After Yukio became an chorister, he was forced to have his blood tested daily in case he might have also received Devil's Blue Flames. In Season 2, Yukio was convinced that he was a normal human. However, during the Kyoto Impure King Arc, Yukio discovered that he had also inherited the devil's blue flames but did not know the extent of it.

Yukio then began to distance himself from his friends and tried to keep this information to himself. However, the Illuminati and Mephisto Pheles were already aware of Yukio's plight. To uncover the truth of his heritage, Yukio will undergo dangerous experimental training to bring the Blue Flames once again.

Yukio has always doubted himself and his abilities. At the end of season 3, Yukio continues to distance himself from the cram school students and his older brother. Yukio probably felt this way because he felt that he had no one to rely on and that he needed to carry any burden himself, so he always did everything in search. Yukio has been keeping secrets most of his life, especially from Rin. As a result, it is possible that Yukio did not know how to confide in his brother about his situation.

Because Yukio is always following his older brother, hoping to gain more power, he soon leaves the True Cross Order of Knights and joins the Illuminati as a visiting researcher. Yukio may have always sought power because he feels weak. Although Yukio could sometimes be seen as an older brother due to his trusting personality, this burden may have led him to defect to the Illuminati in search of answers.
