Naruto Crossover: Grow the Divine Tree and Devour the Myriad Worlds! Current worlds: Jujutsu Kaisen, Mato Seihei no Slave, and Chainsaw Man. (I haven't decided what comes next. If there's an anime you like, leave a comment to let the author know.)
In the Naruto world, he is reborn as Toneri Otsutsuki and inherits the entire moon from the start!
He awakens the [Moon-Building System]. Build bases and recruit gorgeous women to become infinitely stronger!
What's more, the moon is anchored to the Myriad Worlds, and a monster siege is about to begin!
[You have placed Uchiha Izumi in the “Hall of Blossoms,” activating the Harem Module! Reward: One free Sharingan fusion!]
[You killed the Special Grade Cursed Spirit Jogo and successfully defended against the first wave of the siege! Rare building unlocked: Beginner Forge!]
[In the “Martial Arts Hall,” your ancestor Hamura taught you through a stand-in, and you achieved enlightenment in divine-level taijutsu: Complete Eighty Gods Vacuum Attack!]
[You successfully repelled the invasion by Special Grade Sorcerer Satoru Gojo and achieved enlightenment in the Limitless defense mechanism!]
Uchiha Izumi: “Itachi is nothing but a beast who slaughtered his clan! Lord Toneri, Izumi is willing to serve you for all eternity!”
Hyuga Hinata: “That white-haired big brother who came down from the sky... Hinata wants to go to the moon to find him...”
Hanabi: “Big sister, I'm coming too!”
Samui: “Just who is Toneri? He's terrifying!”
Third Hokage: “The entire ANBU force went out, and they couldn't even find a six-year-old brat?!”
Years later, Toneri Otsutsuki sits atop the moon, crushing Susanoo with his left hand and subduing gods and demons across the Myriad Worlds with his right.
Starting by snatching Uchiha Izumi away, he transforms the desolate moon into the strongest harem fortress, one that makes the Myriad Worlds tremble!
It's not like you don't even correct typos, Da Jianmu?
