Facing Ryoumen Sukuna with three fingers, Seiya had no confidence at all. Moreover, Ryoumen Sukuna is moody, and Seiya feels that he has offended him badly last time. Although he is not as good as Gojo Satoru, the number one on the list, he is definitely on his opponent's kill list. The special grade cursed spirit in the juvenile detention center. If Seiya remembered correctly, the opponent was just an ordinary cursed spirit that swallowed Ryomen Sukuna's finger. Although it is a special grade cursed spirit, its domain has only reached the level of "natural domain". Whether it is a cursed spirit or a sorcerer, the biggest difference between special grade and first grade is the mastery of the so-called field. In the world of Jujutsu Kaisen, "domains" are also divided into levels and levels of mastery. The simplest and most common one is naturally the "simple field". Strictly speaking, a simple domain is not a complete domain, but a small domain composed of one or several spells. Its characteristic is that its defense is strong, but its range is small. Although it is not top-grade, it can be achieved through certain talents and skills. And above the "simple domain" is the so-called "innate domain".
The innate domain is a more powerful and complex form of domain, usually created by a powerful soul or mental force. It can also be understood as a concrete manifestation of the user's inner world. As for the last type of field development, there should be no need to say more. The special-grade symbol is almost equivalent to creating an independent space. Seiya has never fought against a special-grade cursed spirit, but as long as it is not a cursed spirit of the level of "territory expansion", he is actually very confident of winning. But Ryoumen Sukuna with three fingers has already surpassed his current level. Now Gojo Satoru is not with them, so Seiya really doesn't want to commit suicide. “Director Ijichi, please let me go in alone for this mission. And if I can't come out after going in, then there would be no point for Yuji and the others to go in. Special-grade cursed spirits are beyond our capabilities. In front of cursed spirits of this level, the number of people doesn’t really matter.” As Yuji and the other two walked over, they heard Seiya trying to persuade Ijichi to let him go in alone. When hearing Seiya's words, Ichichi, who looked tangled, hadn't said anything yet, and Yuji immediately said in a very unhappy tone: "Seiya, what are you talking about, aren't we companions! What do you mean by "Super Curse Spirit is very dangerous, and let us wait outside for news?" Isn't it because it is dangerous that we should face it together? " As we all know, most of the male protagonists in hot-blooded animations have a common problem, that is, they are extremely easily obsessed with learning and attach great importance to their companions. Obviously, the same is true for Itadori now. When he heard that Seiya planned to leave them behind and go into the juvenile detention center alone to fight the special-grade cursed spirits, Itadori had already imagined a different scene in his mind. In Yuji's opinion, Seiya plans to take the risk alone, just because he doesn't want them to encounter any unexpected events, so he plans to take on the responsibility alone. However, what Yuji didn't know was that Seiya chose to go it alone simply because he didn't want to team up with Yuji, which led to him having to face the three-fingered Ryoumen Sukuna, a truly dangerous existence! "Yuji, you have to understand that this time the opponent is most likely a special-grade cursed spirit. I know you are fearless, but have you ever thought about Fushiguro and Kugisaki? And what did you promise Gojo-sensei before? You said you wanted to destroy as many of Ryomen Sukuna's fingers as possible. If you die in there this time, who will destroy Ryomen Sukuna's fingers in the future? And this place gives me a very bad feeling. I can vaguely feel that the magical energy mixed here is very similar to the one in your body, so in order to prevent any unknown changes, you should wait outside obediently this time." While Seiya was trying to persuade Yuji, Ijichi also obtained the consent of the Jujutsu High School over the phone, and this mission would be handled by Seiya alone.
As for the reason, it is very simple. On the one hand, although Seiya is currently a level 2 sorcerer, his actual combat power is comparable to that of a level 1 sorcerer. With his strength, he is indeed more suitable than Fushiguro and the others. The second reason is that as Seiya said, as the container of Ryomen Sukuna, Yuji himself has too many unstable factors. It wasn't a big deal if Yuji died, and the high-ranking officials in the sorcery world were even happy to see it happen. But what if the dead Yuji’s body was devoured by an unknown special-grade cursed spirit? You have to know that Yuji is the container of Ryomen Sukuna. Ryomen Sukuna's fingers may be gone in his body now, but Ryomen Sukuna's consciousness and power still exist. What would happen if other cursed spirits devoured Yuji, who possessed the power of the two-sided Sukuna? Will Ryomen Sukuna be resurrected in other cursed spirits? Or will the swallowed cursed spirit inherit Ryomen Sukuna's power and become extremely powerful? In short, no matter which one it is, such unknown changes are not what the high-level sorcerers want to see. Yuji Itadori can die, but it must be dealt with by their sorcerers, and his body must not be allowed to fall into the hands of the cursed spirits. "Damn it! That bastard Seiya always takes advantage of the hero alone. Will he die if he doesn't show off once?" Seeing Seiya obtain permission from the Jujutsu High School and walk into the "tent" under the barrier alone, Yuji punched the wall with an unwilling look on his face. Fushiguro and Kugisaki, who were standing by, looked at Yuji who had an unwilling look on his face and didn't know how to persuade him. After all, they are not feeling well now, just like Yuji. They both think that Seiya would take on this task alone because the special-grade cursed spirits are too dangerous and he doesn't want others to take the risk. "Yuji, you are really depraved. You actually let your best friend go to find a special-grade cursed spirit to die, while you wait outside with peace of mind." As Yuji smashed the wall in front of him with a punch, a mouth suddenly opened on his arm, and Ryomen Sukuna's slightly sarcastic voice echoed in the air. "Just shut up!" Ryomen Sukuna's words were like a thorn that directly pierced Yuji's vitals. He was already extremely unwilling to give in, and now he smashed the back of his hand against the wall in front of him with an angry look on his face. Unfortunately, however, such behavior could not cause any harm to Ryomen Sukuna, because soon Ryomen Sukuna's mouth appeared on Yuji's other hand again. "If I were you, I would definitely not let my best friend face such a dangerous enemy alone. The human who set up the "tent" is just a weakling. Can such a barrier stop you?" After hearing what Ryomen Sukuna said, Yuji was obviously stunned for a moment, and then looked at the "tent" in front of him that covered the entire juvenile detention center. As for Megumi Fushiguro who was standing aside, when he heard Ryomen Sukuna's voice, he had a premonition that something was wrong. But when he was about to open his mouth to persuade Yuji, he saw the latter running straight into the tent!
