In the world of Jujutsu Kaisen, Sugisawa Third High School in Miyagi Prefecture. "Your Paranormal Research Society will be abolished because you do not meet the minimum requirement of three members. This classroom will also be vacated for those in need." The person who said this was a member of the student council of Shanze Third High School, and the purpose of his visit this time was to announce the dissolution of the "Paranormal Activity Research Society". Facing the aggressive student council members, the president of the "Paranormal Research Society", Sasaki, who had short black hair and ordinary looks, asked in confusion, "Less than three people? What nonsense are you talking about? Is your eyesight bad, or do you not treat us as human beings? We have 1, 2, 3, 4 here. There are obviously four of us. We are one person above the minimum number required for the club. How could there be less than three? " "That is to say, even though the student union has always been dissatisfied with our club, they can't bully us just because we are a small club and don't have an advisory teacher." Hearing his president's words, the even plain-looking senior Iguchi also spoke in agreement. "Um... Sasaki-senpai, and Iguchi-senpai, I'm back at the Home Club. The reason I'm here is because I was forcibly dragged here by this guy Yuji." Hearing that the seniors also counted him as a member of the club, Seiya, who had been dozing off, quickly stretched out his hand to indicate that he was just there to join in the fun. "But even if Seiya is not counted, with me, the seniors and juniors, our club has reached the minimum standard of three people, right?"
Yuji Itadori, who has brown blonde hair and brown eyes, spoke quickly when he heard that his club was going to be abolished. Looking at Yuji who was confused in front of him, and Sasaki-senpai and Iguchi-senpai who were unaware of the truth, Seiya sighed silently. The plot has finally begun, but it’s a pity that no new big boss has come to Xinmeng during this period of time. Although his current strength is not weak, it is still a little insufficient for him to protect himself in the ups and downs of the plot. As expected by Seiya, the next second, a middle-aged teacher in sportswear appeared and said that with Yuji's talent, staying in a useless club like the "Paranormal Research Society" would simply bury his sports talent, so he proposed to duel with Yuji. The plot unfolded as expected, and Seiya did not stop it from happening, including the fact that Yuji brought the finger of "Two-faced Sukuna" to the Paranormal Research Society not long ago. In this world, Seiya is considered to be Yuji's childhood friend. Because Yuji is prone to misfortune, they have often encountered various extras or thugs causing trouble since they were young. If it weren't for the fact that Seiya was born into a ancient martial arts family and that Yuji himself had an unusual physique, he probably wouldn't have survived until now if he had stayed with Yuji. The finger of "Ryomen Sukuna" was picked up by Yuji, which seemed to be an accidental thing, but in fact it was an inevitable result. Even if Seiya tried to stop it, Ryomen Sukuna's fingers would probably appear in front of Yuji in other forms. So instead of changing the plot and making things uncontrollable, it is better to let nature take its course and get Sasaki-senpai and Iguchi-senpai out of danger first. If Seiya is strong enough now, then he will not be afraid of anything, and can even nip all unstable factors in the bud. But the key point now is that he doesn't have the strength to travel around. Even though Seiya didn't watch the shot put competition between Yuji Itadori and Mr. Takagi, he knew the final result directly. As we all know, ordinary high school students in Japanese comics are not ordinary at all, and the same is true for Yuji. With seemingly slender arms, he easily broke the world record for shot put, and this was without any special training. After easily crushing Mr. Takagi and making him doubt his life, he looked at Seiya and said, "Seiya, will you accompany me to visit grandpa today?" Because all kinds of misfortunes always happen around Yuji, Yuji seems to have many friends from childhood to adulthood, but in the end, the only one who can stay by his side is Seiya. Itadori's grandfather is Itadori Yasuke. As Itadori's friend, Seiya actually visits him often.
In the beginning, when Yuji introduced himself to his grandfather, the other party was a little disliked him. Yuji has always regarded this kind of dislike as his grandfather having a weird temper, and Yuji even told Seiya that his grandfather has always been alone because of his personality. But Seiya disagrees with this. Seiya does not deny that Itadori Yasuke has a weird and stubborn temper. But Seiya could feel that Itadori Yasuke's dislike for him did not seem to be because he hated him, but more like Itadori Yasuke felt that it might not be a good thing for Seiya to stay by Itadori's side. This situation continued until the last time when Seiya and Itadori came to the hospital to visit Itadori Yasuke again. The look in his eyes when he looked at Seiya suddenly began to change. After sending his silly grandson out of the room with an excuse, Yuji Yasuke looked at Seiya with a serious look and said, "I didn't expect you to become a sorcerer, have you been affected by Yuji's curse? I just don’t know whether it is a blessing or a curse for you to have obtained this power.” When Seiya, who was in the ward, heard what Itadori Yasuke said, he was obviously stunned. Because when Seiya first came with Itadori to visit his grandfather, Seiya had not yet shared the power of other Seiyas in the "Heart and Dream". Although he was good at ancient martial arts at that time and his physique was as different from ordinary people as Yuji, there was no aura of cursed power on him. This time, when Seiya came to visit Itadori Yasuke, he had already shared the abilities of Seiya from other worlds. The spiritual power of the Tokyo Ravens world was transformed into an equal amount of cursed power in this world. As Itadori's grandfather, Itadori Yasuke was not introduced much in the original plot. Even at the beginning, Seiya always regarded him as an ordinary old man who knew a lot of things. But now it seems that the old man who seems to be dying is not ordinary at all! Are you kidding? If it was an ordinary old man, would he be able to detect his deeply hidden cursed power? "Curse? Is there any curse on Yuji? Grandpa Yasuke." Seiya can’t say that he is completely unaware of the plot of Jujutsu Kaisen, but he doesn’t know much either. Because when he traveled through time, the first season of this thing had already been released, and now when he realized that the old man in front of him might be a hidden boss, Seiya naturally tried to see if he could get more useful information from him. "With your current strength, knowing too much is not a good thing for you. The reason why I didn't pay any attention to you before was that I didn't want you, as an ordinary person, to have too much involvement with Yuji, thus bringing misfortune upon yourself. But now it seems that you have been affected, otherwise you wouldn't have changed from an ordinary person to a sorcerer."
