This week Jujutsu Kaisen starts a Sci-fi sequel Modulo. The leads are the grandchildren of Yuta and Maki the protagonist of the movie and the senpai of the main cast. Well, its smart to use an already establish IP with a built in audience instead of creating a new one whole cloth. He also used grandchild instead of children and from a pairing no one had issues with.
Hopefully this one works out better than Kishimoto's did.
