Sarutobi Hiruzen awakens within a mystical subspace after a heated online forum confrontation, flooded with knowledge from countless dimensions. Transformed by this revelation, he orchestrates a radical reimagining of the shinobi world through the construction of Shinobi Academy City. No longer content with passive leadership, Hiruzen pursues cross-dimensional commissions—neutralizing Sukuna's curse, eliminating the Chimera Ant King, and deploying elite shinobi across worlds. He positions Itachi Uchiha at the Summit War while empowering the Demon Slayer Corps through Orochimaru's enhancement to confront Kokushibo. Educational alliances with Hogwarts reshape the ninja landscape. Antagonists face decisive elimination rather than redemptive second chances. "My first reign as Hokage: too inexperienced. The second: too weary. What have I built? Everything burned away." --- [No-Conspiracy Hokage] [Interdimensional Chat Group] [Konoha Mercenary System] [Traverses: One Piece, Demon Slayer, Jujutsu Kaisen, Hunter x Hunter, Harry Potter, Warcraft, and Beyond]
