After transmigrating as Hyuga Xiao, a member of the Hyuga Branch Family, he has the humiliating Caged Bird Seal carved into his forehead. At the depths of despair, he awakens the [Fate-Breaking System]. By stealing the opportunities of high-fortune kunoichi from the original story, he can continually purify his Byakugan bloodline and unlock the power of the Otsutsuki!
"Ding! You stole Hinata Hyuga's opportunity. Byakugan purity +50%. Caged Bird Seal removed!"
"Ding! You stole Kurenai Yuhi's opportunity. Reward: Tenseigan Chakra Mode!"
To take control of his own fate, Hyuga Xiao sets out on a ruthless path of stealing opportunities.
Hyuga Hiashi: "You're from the Branch Family. What makes you think you can marry my daughter?!"
Hyuga Xiao activates the Tenseigan and splits the moon with a single strike. "This is what makes me worthy, Father-in-law. Any objections?"
The timeline is messed up, Orochimaru didn't defect, and Hinata wasn't even born.
