The Jūgo Arc, also titled the Cursed Seal Infection Arc, is the eleventh storyline of the Boruto: Naruto Next Generations anime. Spanning a short run of episodes, it returns Jūgo to the spotlight while a cursed-seal outbreak becomes its driving concern.
This brief arc, which the anime lists as its eleventh, covers episodes 98 through 103 of Boruto: Naruto Next Generations. It carries a second name, the Cursed Seal Infection Arc, sometimes rendered as Shadow of the Curse Mark. Within the broader run of the series it comes after the Parent and Child Day Arc and leads into the Steam Ninja Scrolls Arc.
As its alternate title signals, the storyline turns on the danger of a spreading curse-mark affliction, with Jūgo, whose body has always been tied to that power, placed at the heart of the events. The arc runs a compact six episodes, keeping its focus tight around this returning figure and the threat his condition represents to those around him.
Once these episodes conclude, the anime moves directly into the Steam Ninja Scrolls Arc, which takes over as the following chapter of the series. The Jūgo Arc thus serves as a short, self-contained interlude between two larger runs of story.

We ranked the six most popular women of Naruto from worst to first, and our number one is going to start a fight. The official poll got it wrong....

The transformation everyone knows, the follow-up question nobody would touch. Why we made a smooth R&B track about the golden glow Dragon Ball never talks about....
