S Class (S クラス S kurasu?) refers to the group of beings with the highest class (the pinnacle of power in the YuYu Hakusho universe).

Characteristics[]

In Demon World, it was said first that there are only about 20 known demons in this class. However, this has being later discredited. In the manga as well as the English dub of the anime, Mukuro clearly labels Shigure as the weakest of her 77 elite, implying that they are all S Class. Also, Raizen's Friends were hidden all the time and not even Mukuro and Yomi knew of their existence.

During the Demon World Tournament, at least 27 fighters are confirmed to be S Class level. To those, Kuwabara can also be considered as another one, since he entered the Second Demon World Tournament by the end of the Eizou Hakusho OVA.

Outline[]

Being the strongest in the class system, they are completely humanoid with some non-human features like pointy ears, or horns, or none at all, appearing to be completely human. The general personality of the S Class is to be very reserved, not often letting their emotions decide things, but rather experience.

Each S Class demon has immense power, earning the fears of the Spirit World, as they are capable of destroying the planet, both in immense strength and powerful energy based abilities such as barriers, blasts, and dimension distortions.

Rulers of the Demon World[]

This detaches them from humanity, making them similar to ascended beings, as seen with Yomi, Mukuro and Raizen, three S Class user that have managed to rule the Demon World for centuries. As the finale drew nearer, S Classes that have human-like emotions like laid-back natures, grief and respect for their enemy who were all friends of Raizen, showing a complete contrast to the lowest classes that lived in fear, had no respect for one another, let alone their opponents and extreme arrogance. The S Class has displayed some of the most friendly and patient characters in the series, and likely implying a future that demons would one day become similar to this nature.

In fact, the most carefree demon of all, Enki becomes the current ruler of Demon World.

Hiei and Kurama[]

Kurama and Hiei had also reached S Class during the Three Kings saga. At the end of the manga and anime, Kuwabara could have reached the Lower S Class or a higher level as well, but he stopped only at Middle to Upper A Class to focus on his studies. He ascends to S Class at the end of the manga, and in Eizou Hakusho by the time of the second Demon World Tournament.

Humans[]

In the case of humans, S Class power can only be achieved by attaining and mastering sacred energy as it has been stated that spirit energy has limits to its growth. Only two humans have reached this level.

First, Sensui with his Sacred Energy who was as strong as an S Class Demon, was able to defeat two A Class Demons and Kuwabara by himself with relatively little effort. Sensui's full power was said to be at this level, as was Yusuke's when he came back to life as a Mazoku.

Finally, Kuwabara with his eventual mastery of the Dimension Sword. With Kuwabara, it is the fact that he gained specialized power due to the transformation of his Spirit Energy after his body sensed the threat of the gate to Demon World, and began preparing him for it.

Yusuke's case[]

Since Yusuke has dual ancestry, he is no longer considered human. In fact, it was his demonic transformation that allowed him to attain the S Class level after his revival in his battle against Sensui.

Trivia[]

  • Either Raizen, if he had continued to eat humans and retained his immense power, or Mukuro, if she remained enraged, would be the strongest characters in the series.
  • Three of the main cast had reached S class by the end of the manga, while the fourth, Kuwabara, is both the weakest, and ironically the strongest full human on Earth after Sensui's death. In the anime, Kuwabara stopped in the Upper A Class level, although he would later achieve it in the OVA Eizou Hakusho.
  • Kurama's allies (Team Kurama) are Upper A Class in the anime, which is inaccurate because they held their own against powerful S Class demons in the anime. In the manga, they are all stronger than typical lower S Class demons. Even so, Chu held on his own after a year of training, reaching Upper S Class, which puts him near the level of his mentor/love interest Natsume.
  • S Class demons have been shown to be the most emotional in the show. This points to their integrities being more human-like than any other class, in general.
  • In Chapter 152, Kurama states that the S Class refers to any warrior the Spirit World is incapable of defeating. Under the S Class label, many demons with different power levels are conflated - from low level underlings to god-like creatures. This also fits in line with the SDF commander Ootake's statement that there is a god-like difference between the Three Kings and their second in commands. Further, Kurama also mentions that the upper S Class demons consider the rankings by Spirit World a borderline insult as it lumps them in with the lower S Class demons that they use as servants.
  • It is heavily implied that Demons and Humans become ten to twenty times more powerful when they ascend from upper B Class to low S Class, because it was stated by Shinobu Sensui that he was using less than 50% of his full power, but still had ten times more Spiritual energy than Yusuke, who was an Upper B class when he first fought against Sensui.
