In Mist Year 64, Seiji encountered the ninety-year-old Genji, who recognized him as the child of an old acquaintance despite believing that Seiji had died young. Seiji revealed that he wore Kirigakure’s Mizukage’s Divine Robe, then used the Tenseigan to draw Genji into a genjutsu and begin communicating.

After learning about this world's Genji and his family, Seiji left Kirigakure and went to find Black Zetsu during the Fourth Great Ninja War. He sensed an old acquaintance near the Daimyo's residence, leaving him poised to confront Madara.

• Black Zetsu tried to escape Seiji's Barrier after his ambush on the daimyo failed, believing Obito had gone to capture the Eight-Tails and Nine-Tails Jinchuriki.
• Seiji appeared beside the Barrier and greeted Black Zetsu, who mistook him for Otsutsuki Hamura because of his horns and Otsutsuki aura.
