In Year 20 of Konoha, Shirasaki Shiro has been living in the Naruto world for 16 years, serving in the shadow guard of Second Hokage Senju Tobirama.
Trapped by the Gold and Silver Brothers and their elite force during the First Shinobi World War, someone needed to stay behind as a decoy. Stepping up before Sarutobi Hiruzen could even open his mouth, Shirasaki declared without hesitation: "I'll cover the retreat!"
Moved by his resolve, Senju Tobirama named him on the spot: "From this day forward, you are the Third Hokage of the village!"
Upon taking the Hokage seat, Shirasaki activates the [Konoha Development System]. Prestige, education, technology, military power, economy, and diplomacy-every time Konoha advances, Shirasaki receives game-changing rewards.
But leading Konoha is no easy task. With Tobirama dead, rival nations test the borders while internal dissension brews from those unhappy with his appointment. From the chaotic First Shinobi World War to unifying the Ninja World in the Fourth War, Shirasaki turns Konoha into an absolute empire-until the Otsutsuki Clan descends.
"Another Otsutsuki?!"
"These guys are rare research materials!"
"Understood, go easy on him-we need him alive!"
As Tsunade folds her arms, Orochimaru licks his lips in excitement, and Jiraiya leaps onto an Uchiha Susanoo in Sage Mode, multiple Susanoo and Nine-Tails beasts surround Otsutsuki Isshiki.
Sitting high above the battlefield, Shirasaki smiles: "Mere Otsutsuki... Konoha's future lies in the sea of stars!"
