Ch. 1This Is Called Severing Cause and Effect!
Chapter Summary: “This Is Called Severing Cause and Effect!”
Key Plot Points and Events
- Riu, a Naruto fan, transmigrates into Obito at the moment Rin dies, discovering that the scene is real rather than a dream.
- Unlike the original Obito, Riu recognizes Madara’s manipulation and refuses to be emotionally broken into serving the Moon’s Eye Plan.
- He stores Rin’s corpse inside the Kamui Dimension, intending to preserve her for the future.
- Riu finds Kakashi unconscious and removes Kakashi’s left eye, reclaiming the Mangekyō Sharingan that originally belonged to Obito. He implants it into himself, gaining dual Mangekyō Sharingan and access to the full power of Kamui.
- He returns to Madara’s underground base and pretends to accept the role of Madara’s successor. Riu claims that he wants to create a dream world containing Rin and Kakashi.
- Madara explains the Ten-Tails, Infinite Tsukuyomi, Six Paths Techniques, Yin–Yang Release, and his plan to be resurrected through Nagato.
- Before dying, Madara names Obito as “Uchiha Madara” and entrusts him with carrying out the plan.
- Once Madara dies, Riu reveals his true intentions: he plans to alter the established plot, become the Ten-Tails’ jinchūriki, and prevent Madara’s resurrection.
- Riu immediately turns on Black Zetsu and uses Kamui against him, declaring that this is how he will “sever cause and effect.”
Character Developments
- Riu/Obito: Quickly adapts to his transmigration and uses his knowledge of the original story to avoid Obito’s fate. He becomes calculating, ambitious, and willing to take ruthless actions to secure power, while still showing some restraint toward Kakashi.
- Rin: Although dead, Rin remains central to Riu’s motivations. Her corpse becomes something he intends to preserve rather than simply mourn.
- Kakashi: Survives Rin’s death but loses his left eye, which Riu takes for himself. This marks Riu’s first major alteration of the original timeline.
- Madara: Successfully believes that Obito has fallen into despair and accepts him as his successor. He dies without realizing that Riu intends to betray and surpass him.
- Black Zetsu: Revealed as a direct extension of Madara’s will, making him one of Riu’s first major obstacles.
Significant Themes
- Free will versus manipulation: Riu understands that Rin’s death was orchestrated to control Obito and attempts to break free from Madara’s predetermined plan.
- Changing fate and causality: The chapter focuses on Riu’s desire to rewrite the Naruto timeline rather than repeat it, symbolized by his declaration to “sever cause and effect.”
- Power and moral compromise: Riu protects Kakashi’s life but brutally takes his eye, showing that his goals outweigh conventional morality.
- Knowledge as power: His familiarity with Naruto’s events gives him an enormous advantage over Madara and the other characters.
- Identity and deception: Riu must convincingly perform the role of Obito while secretly planning to betray Madara’s entire scheme.
Character Interactions

- Riu and Kakashi: Riu examines Kakashi, spares his life, but removes his inherited Sharingan and implants it in himself.
- Riu and Madara: Riu deceives Madara by pretending to embrace despair and the Infinite Tsukuyomi. Madara trains and empowers him, unknowingly preparing his own replacement.
