User:ArtistOfTheDaleks created the Starfruit through research and stuff collaborating between Kintaro Uchiha and Team Kamikaze with the Fifth Hoshikage Sumaru. This allowed those who ate the fruit the ability to naturally generate star chakra WITHIN their bodies. Artist wrote most of the article; I just wrote its role in the Second H-H War.
