The Rinnegan is the ultimate Kekkei Genkai, but Boruto has officially bid farewell to it in Two Blue Vortex.
The Rinnegan is a godly power that has sadly been nerfed and surpassed by a new Kekkei Genkai in the Boruto series.
Itachi once stood as a master of Genjutsu in Naruto, but Boruto lines up its own God of Genjutsu decades later.
The Tailed Beasts went their own way at the end of Naruto, but Boruto is bringing them back in a brand-new way.
