Knotweed Yuhito may be killed by Wasabi in the ending of Jujutsu Kaisen.
After the death of Tsusuo, the status of the two-faced suku has risen to the status of the only villain in Jujutsu Kaisen, and now he is engaged in the final battle with the key characters.
The series is known for its willingness to kill the main characters, as evidenced by the deaths of people like Kento Nanami and Rose Tsubashi.
The strong possibility of Knotweed Yuhito's death has been hinted at in the series, and his eventual death may come at the hands of a powerful and ruthless two-faced suzu.
Jujutsu Returns is going very strong at the moment, and fans are extremely excited about the climax of the Knockout chapter. Currently, Two-Faced Suo is at the forefront of the villain's side, and since Tsuso has died, he is now the only villain in the series.
Now, the two-faced Subu may be in the final battle with Otoku, Rika Kemoto, and Knotweed Yuhito. While this fight is destined to be very exciting, fans know that this fight will most likely end up leaning towards the two-faced skubu. Jujutsu Kaisen has never shied away from killing characters, and even if they are the main characters, of course, Knotweed Yuhito may end up dying.
Fans already know that Jujutsu Kaisen is a series that is never afraid to kill the main characters. In fact, fans have seen a lot of characters who are loved all over the world fall prey to the author's brutal writing. From the very beginning of the series, some incredible characters have died, such as Junpei, who immediately caught people's attention. Although he was only a supporting character, some of the main supporting characters eventually fell as the series progressed. Characters like Kento Nanami eventually die in the Shibuya chapter, and in the same chapter, Rose Tsukizaki – one of the three main characters of Jujutsu Kaisen – also dies, causing the biggest shock to fans.
When Nail Roses died, it became clear to fans that no one in the series was safe. In fact, the author himself has commented that he may also end up killing his main character, which turns out to be even more true when the knockout begins. In this chapter, many other characters also meet their endings, and by far the biggest shock is the death of Satoru Gojo. Satoru Gojo was unsealed in the knockout chapter, and after a long and difficult battle, he ended up falling victim to the two-faced suku. Unfortunately, Satoru Gojo was unable to defeat him and eventually died in the process. From there, many other characters also encountered death, such as Shikashi Yunichi and Hinakura Kanmi. Now, Knotweed Yuhito is at the center of things, and it looks like he might end up dying as well.
While at times people might think that Yuhito Knotweed wouldn't die in the series due to the fact that he was the main character, they couldn't be more wrong. Of course, Knotweed Yuhito as the protagonist does mean that he has a lower chance of dying than some other characters who have a lower importance by default in the story, but that doesn't protect him from death. In any other series, perhaps, he would be safe due to Knotweed Yuhito's starring status, however, that's not how Jujutsu Kaisen works. Knotweed Yuhito is a character who is likely to die eventually, and there are already hints about this in the series.
In fact, Knotweed Yuhito's entire character arc revolves around the fact that he wants to help as many people as possible before he dies. This essentially does open a way for the death of Knotweed Yuhito. As long as he helps many characters and then dies, he will become a person who has successfully achieved his goals. There's already a groundwork for Knotweed to die in Jujutsu Kaisen, however, all fans need to be clear about is how he's going to die, if he does. By far, the most likely death scenario for Knotweed Yuhito is if he manages to help everyone around him and save countless lives. In the process, he will give up his life and die from the death of a hero. It would be the perfect ending for a character like him, as he is a man who is not afraid of death, and at the same time, he is also a man who wants to save as many people as possible.
When it comes to the death of Knotweed Yuhito, one might wonder what could have killed him. The answer to this question is not difficult. The Two-Faced Subu, the Lord of the Damned, is the most powerful individual in Jujutsu Kaisen and is currently fighting Knotweed Yuhito and is likely to be the one who killed him.
Fans know that the two-faced skutsu is very powerful. He is the strongest wizard in history and has reached the pinnacle of spell wizards. The two-faced Subu possesses such great power that even Satoru Gojo will not be able to outperform him in battle. Now, Knotweed is challenging him, however, fans have clearly seen that he is nowhere near his level.
The two-faced sufu himself commented on the difference in strength between the two, and this gap is definitely huge. However, Two-Faced Subu also admits that Knotweed Yuhito has an indomitable spirit that helps him get back up every time he falls. This indomitable spirit will help him go far, however, in the end, if he falls, it will certainly be in the hands of the two-faced supreme. Currently, the goal of the two-faced sufu is to crush the will of Knotweed Yuhito and kill him in the process. Knotweed Yuhito will make great strides in his fight against the two-faced Subu and is sure to impress fans, however, the possibility of his death remains. 
All things considered, fans shouldn't be surprised that Knotweed Yuhito could die at the end of the knockout chapter, especially if he ends up in a fight to defeat the two-faced skubu. If all this wasn't enough to convince fans of the possibility of Knotweed Yuhito's death, then, perhaps, fans should consider that a long time ago, when Jujutsu Kaisen was in its infancy, the series might have been axed from Shonen Jump. At that time, the author decided to let Yuhito Knotweed die after his heart was torn apart by the two-faced skubu, and later provide a quick ending for the supporting characters to end the series. In addition, the author also stated that he doesn't care who he kills in the end, as long as it helps to make the story interesting. Everything suggests that no character in Jujutsu Kaisen is safe, not even the protagonist Knotweed Yuhito.
Of course, there is absolutely no *** knotweed Yuhito will die, however, fans always have this possibility in the back of their minds. The chances of Knotweed Yuhito dying in Jujutsu Kaisen are there, and it's likely that this will happen soon as the series draws to a close.
