Summary:
Satoru Gojo meets Megumi Fushiguro in first grade and explains his situation with the Zenin family. Satoru promises to take care of everything for the child, planting the seeds of what would become a thriving teacher-student relationship eleven years later. In the current year of 2018, Jujutsu High’s mole is exposed as the calendar approaches October 31st in Shibuya.
Plot:
Satoru assures baby Megumi that he will take care of everything
Satoru tells Megumi that he will take care of everything regarding the Zenin Clan.
Satoru finds and talks to Toji’s son, young Megumi Fushiguro. He tells Megumi that his father is from the Zenin family, which he left to have his son.
The Zenin Clan loves people gifted with cursed technology. Megumi is nearing the age where his technique will show, making it the perfect time to sell him to the Zenin. This was Toji’s trump card against them, which is unfortunate for Megumi.
The first grader replies that he doesn’t care about his father, and Tsumiki’s mother hasn’t been back for a long time either. She believes they used the “divorce money” to run away and live happily together without them. Satoru asks Megumi if she wants to go to the Zenin family, but the boy is just worried about what will happen to Tsumiki.
Satoru taunts him about it, just to get Megumi. When the young man glares at him, insisting that Tsumiki can’t be happy, Satoru is satisfied. He promises to take care of things for Megumi and asks him to get stronger.
Eleven years later in the present, on October 19, 2018, Gojo sensei wakes up from a dream about all these past events in his life. He wakes up to his three students, including Megumi, looking at him. Gojo smirks at his longtime protégé, proud of how he’s grown since then, confusing Megumi. Shortly after, Gojo informs them of the Jujutsu High mole and sends them to meet Utahime. He tells them that there are two moles, one of which is one of the higher Jujutsu. Since there is nothing they can do about it at the moment, their main target is anyone who supplies information to the above.
Nobara asks if the mole is someone from Kyoto, which surprises Yuji. As Utahime prepares to reveal who he is to them, Kasumi encounters Mechamaru elsewhere. She tells him that they have notebooks today and he replies that he will sleep all day. Back at Mechamar’s supposed hideout, Utahime informs the Tokyo first years that he must be the one in the process of elimination.
Using Puppet Manipulation to steal information wouldn’t be difficult for someone like Mechamaru. At the same time, Kokichi Muta is preparing for his visitors. However, Yuji falls through the door into the fake hideout and confirms to them that he is the mole. In his real hideout, Kokichi meets Mahito and Pseudo-Get. He chides them for taking it with them, but Geto assures him that he will never break his binding promise.
Kokichi claims they broke a binding vow by hurting the people of Kyoto, but Mahito claims it was Hanami’s. He demands that he hurry up and cure him, annoying Mahita. However, Geto makes it very clear that they cannot risk breaking a binding promise with another person. Mahito reluctantly uses Idle Transfiguration to heal Kokichi, giving him a healthy body for the first time. Mahito says that he should be more excited, but Kokichi saves that for when he gets his affairs in order. With no more words to be exchanged, Kokichi and Mahito clash.
