Action

He wasn’t born in this world — but fate gave him a second chance.
    Reborn into the chaotic era of shinobi, Riku awakened with a body unlike any other.
    One that could grow stronger without limit. Chakra, speed, endurance — everything sharpened with time, endlessly.
    Knowing that power like his would paint a target on his back, Riku played the long game.
    He stayed quiet. Humble. Weak, even.
    He even threw a match against Hinata during a basic taijutsu assessment, just to stay under the radar.
    Unfortunately, subtlety wasn't his strong suit.
    “That wasn’t a loss,” Kakashi murmured, watching from the shadows. “That was bad acting.”
    But the whispers started anyway.
    Hinata, gentle and kind, found her thoughts drifting more and more toward the quiet boy with an unreadable gaze.
    "Riku… why do you keep appearing in my mind like this? What's happening to me?"
    Tsunade, ever the battle-hardened Hokage, watched his progress with interest — and a rising sense of unease.
    "This kid... if his power keeps growing like this, he might surpass every Hokage before him."
    But Riku’s secret wasn’t his alone to bear.
    When Kaguya Ōtsutsuki returned from beyond dimensions, she didn’t see him as an enemy — but as a peer.
    "The Ōtsutsuki will come for you. Stand with me, Riku...."
    Even Hashirama Senju, long considered the peak of Wood Style mastery, was stunned by what he saw.
    "No… this isn’t just my jutsu. His Wood Style is alive. It’s something else entirely."
    And in the depths of hatred, Madara Uchiha seethed as he sensed something impossible.
    “That brat… why does he have a Rinnegan?! This isn’t how it was supposed to go!”
    From humble beginnings to cosmic stakes —
    Riku wasn’t meant to be just another shinobi.
    He was reborn to reshape the fate of the entire ninja world.
