Miguel/Synopsis

Cursed Child Arc
Miguel along with the other leaders were summoned to a meeting with Suguru Geto in his religious group temple about creating a paradise for sorcerers. After the meeting, Geto brings Mimiko, Nanako and Larue to Tokyo Jujutsu High so he can meet with Yuta while Miguel and the others stayed behind.

On December 24, Miguel is in Shinjuku and talks with Manami Suda about how they are just the distraction. He notices Satoru Gojo. When Satoru teleports two of his students back to Jujutsu High, it surprises Miguel and Manami, with Manami wondering whether they noticed Geto being in Jujutsu High, with Miguel replying that they should start the war immediately. When the war starts, Miguel confronts Satoru. As Miguel fights Satoru, Miguel is put on the defensive as his Black Rope is getting shorter due to being used to disrupt Satoru's technique. Miguel then asks Satoru how many decades he thinks it took for his country's sorcerers to make the Cursed Tool, who brushes off the question. When a cursed spirit appears and attacks Satoru, Miguel sees Satoru use his technique to exorcise the spirit. Miguel thinks about what Satoru's technique is capable of and how he has to last just ten more minutes before meeting his quota. Miguel then curses Geto for taking long.

Some time later, Miguel retreat along with the other leaders.

At some point of time after the battle, Miguel would be recruited by Satoru and he would leave Geto's group and become an ally to the Jujutsu Society.

Kyoto Goodwill Event Arc
Miguel trains Yuta Okkotsu with the help of his community while Yuta is overseas in Miguel's home land in Africa.

Perfect Preparation Arc
While discussing on how they could free Satoru from the Prison Realm, Master Tengen informs the group that they must have either Inverted Spear of Heaven which nullifies cursed techniques or the Black Rope that disrupts and cancels cursed technique effects. However, they reveal that the Inverted Spear Of Heaven was either destroyed or sealed overseas by Satoru 11 years ago, and the Black Rope was destroyed by Satoru the year before. The others are surprised and wonder why Satoru destroyed these tools. Yuta mentions that he was searching for the remaining Black Rope in Africa while overseas, with Miguel helping him in his search for the rope in his sorcerer community with no success. While mentioning about it, Miguel appears in a flashback where he told Yuta that there was no rope left in his community.
