Chapter 79

A Taste of Things to Come (これからの) is the seventy-ninth chapter of Gege Akutami's Jujutsu Kaisen.

Summary
Gojo explains to (child) Megumi about his father and how he was a part of the Zen'in sorcerer family. He starts to say that he killed Megumi's father, but Megumi interrupts saying he doesn't care about his father. Megumi talks about how neither his father nor Tsumiki's mother has been back in a while and concludes that they're done taking care of them. Gojo asks Megumi if he wants to go to the Zen'in family, but Megumi asks if Tsumiki would be happy. Gojo guarantees she wouldn't be, and Megumi's angry face gives his answer. Gojo leaves and says he'll take care of things, but Megumi has to work hard.

Back in present time, Itadori, Fushiguro (Megumi), and Kugisaki wake Gojo up because he'd summoned them.

Later, in a parking garage, Utahime meets Itadori, Fushiguro, and Kugisaki and tells them who she suspects the mole is, the one who's giving information to the enemy curse users. Just as Utahime is about to say who it is, the scenario switches to Miwa saying Mechamaru's name (presumably in Kyoto Jujutsu High). She and Mechamaru, speaking through his metal puppet, have a talk but Mechmaru says he's going to sleep.

Meanwhile, Utahime, Itadori, Fushiguro, and Kugisaki infiltrate where they think Mechamaru's real body is. However, they find the place empty and realize they've been had, and Mechamaru is confirmed as the mole.

The real Mechamaru (Muta) is meeting with Geto and Mahito. The deal, made with a binding vow, was that Mechamaru's body would be healed in exchange for his cooperation and information. One of Mechamaru's conditions was that nobody from Kyoto Jujutsu High would be harmed, which he states they broke. Mahito tries to say it wasn't his fault, but Geto explains it's a bad idea to break a binding vow with someone else because the penalty is unknown. Thus, Mahito heals Mechamaru with Idle Transfiguration. Mechamaru and Mahito prepare to fight.
