Guess I was wrong about the origin of boruto’s eye it actually was given to him by toneri. But apparently whatever the jougan is toneri gave boruto an incomplete or weaker version since urashiki said it was hastily prepared and I’m guessing it will get stronger over time it even be further powered by the ootsutsuki curse seal.
