In the final years before the fall of the Uchiha Clan, Ethan Uchiha is revealed to be the younger brother of Shisui Uchiha. Unlike the prodigious Shisui, whose mastery of the Sharingan and the legendary Kotoamatsukami made him one of the most feared shinobi of Konohagakure, Ethan grows up in the shadow of his brother’s reputation while witnessing the growing tension between the Uchiha and the village. As the clan secretly prepares for the Uchiha coup d'état, Ethan becomes caught between loyalty to his family and the ideals Shisui fights to protect. While Shisui works alongside Itachi Uchiha to prevent civil war, Ethan discovers the truth behind the coup and the dangerous political conflict threatening to tear the village apart.
