Not at all. Yuji Itadori's story doesn't end with his execution in the manga. There are many developments and challenges he faces, but execution isn't one of them.
Yuji Itadori survives till the end. The manga doesn't have his death as the final outcome. The story might have thrown challenges at him, but he manages to overcome them and remain alive.
There could be a fanfic that focuses on Luigi's training to control his death stare. He might seek out the help of a wise old Toad who has knowledge of ancient powers. This would make for an interesting story as Luigi tries to master this power without causing harm to his friends.
It often shows the fragility of life. For example, in many post - apocalyptic sci - fi stories, characters are constantly facing threats that could end their lives. This makes the reader or viewer acutely aware of mortality.
There might be a fanfic where Luigi's death stare is misinterpreted. His friends initially think he has turned evil because of it, but later they discover it's a new power he has gained to protect them from a hidden threat that can only be detected by this intense stare.
One notable work could be 'The Andromeda Strain'. It involves a deadly extraterrestrial microbe that threatens humanity, with scientists racing against time. The 'stare of death' aspect can be seen in the sense of the impending doom that the microbe represents.
Itadori did indeed die in the manga. His death had a significant impact on the story and the other characters. It was a turning point that led to many new developments in the plot.
Itadori is quite powerful in the manga. His strength lies not only in his physical abilities but also in his determination and the unique powers he acquires along the way. He's able to face off against formidable opponents and come out on top more often than not.
