"I'll pass. Aren't Sasaki-senpai and Iguchi-senpai holding a club meeting tonight to open that thing you found at the school? I'm interested in their club activity tonight, so I'll go with them." Seiya thought about Yuji's invitation to visit Wasuke at the hospital and ultimately refused. The old man was not a normal person and knew a lot, which was a certainty. But the old man was tight-lipped. Seiya had tried to get information from him many times but had failed, so he had given up. Instead of going to the hospital to get scolded by the old man with Yuji, Seiya decided to stay and watch over Sasaki-senpai and Iguchi-senpai.
In the original story, even after unsealing Ryomen Sukuna's finger, they were not easily killed by the cursed spirits that were attracted, unlike Junpei Yoshino's mother. But anime is anime, and reality is reality. Sasaki-senpai and Iguchi-senpai were his seniors, and he had a good relationship with them. How could Seiya risk their lives? If Yuji and Megumi Fushiguro were even a little late, who would be to blame if Sasaki-senpai and Iguchi-senpai were killed by the curses? Since Seiya had decided to let the plot unfold as it should, he was responsible for their safety.
Night fell, and Yuji had arrived at the hospital. Wasuke, feeling that his death was near, wanted to talk to Yuji about his parents, but Yuji kept interrupting him. That Seiya kid always finds a way to ask me about the past, and I never say a word. Now, when I finally want to open up, where is he?
"Seiya said he was worried you'd scold him again, so he's probably with the senpais right now."
Hearing that Seiya hadn't come, Wasuke was a bit disappointed. At the end of his life, a person always wants to have more people around them. Although Seiya wasn't his grandson, the boy was always talking to him, and Wasuke had long since come to see him as another grandson.
"Yuji, you're strong. So, go help people. Help as many as you can, but within your limits. It's okay to be lost, and don't worry about being unappreciated. Just do your best to help others. You should die surrounded by people, not like me." Then, thinking of Seiya, Wasuke remembered his last conversation with the boy. Seiya had suddenly gained cursed energy and had gone from a normal person to a Jujutsu Sorcerer, which Wasuke saw as a kind of misfortune. While jujutsu was an extraordinary power, Wasuke didn't see it as a gift from the world. With great power comes great responsibility. Compared to ordinary people who could live a peaceful life, very few Jujutsu Sorcerers lived to an old age or had a peaceful end. So, to Wasuke, Seiya's new power was a kind of misfortune, and it probably came from Yuji's curse. But what Seiya said in response had left even the worldly Wasuke in a daze for a long time.
"It doesn't matter to me whether this power brings me misfortune or not. But I know that without power, I can't protect anyone. If a tragedy were to happen right in front of me, and I couldn't stop it, that would be the real misfortune!" Seiya knew where his power came from. If misfortune meant having power, he wished for more. Being a normal person wouldn't guarantee a peaceful life. Don't you see, the brain-eating monster is already planning to kill all humans without cursed energy?
Wasuke died, and at the same time, in a classroom at Suginami High, the Occult Research Club's dangerous activity had begun. As Sasaki-senpai peeled off the talismans on Ryomen Sukuna's finger one by one, Seiya felt a sense of tension. This was Ryomen Sukuna, the King of Curses from a thousand years ago. Even in the golden age of jujutsu, he was the strongest. Even with just one finger, Seiya couldn't let his guard down. A single finger of Sukuna was a Special-Grade cursed object, powerful enough to create a Special-Grade cursed spirit.
As Sasaki-senpai peeled back the layers of talismans, the three of them could feel the atmosphere around them becoming sinister.
"I suddenly feel cold. This thing really isn't normal. Should we give up for tonight?"
The candle flickered in the dark classroom. They had closed all the windows, but a cold wind was blowing.
"What are you talking about? We've come this far. We can't back down now. The purpose of our 'Occult Research Club' is to explore these unknown phenomena. This atmosphere is perfect!"
Sasaki-senpai was the club president, and Iguchi-senpai was a member for a reason. Although she was also terrified, Sasaki-senpai's curiosity was too strong. She was the one holding Sukuna's finger and peeling off the talismans herself.
BOOM!
The moment the last talisman was removed and a reddish-brown, clawed finger was revealed, a pale, giant arm crashed through the ceiling, aiming for where Sasaki-senpai was sitting. But a figure standing to the side was even faster. Just as the arm was about to hit, Seiya shot out and, with a princess carry, swept Sasaki-senpai into his arms and slid several feet away.
ROOOOAR!
As Seiya saved Sasaki-senpai, a disgusting, multi-tentacled blob of a curse smashed through the window, extending its tentacles towards Iguchi-senpai, who was still frozen in shock.
