When he was five years old, Hao Ruikeqingren saw the flow of chakra for the first time in the leaf control class at the Ninja School.
From then on, Konoha was no longer just a familiar village in his eyes, but a network full of cracks: the uncontrolled dark red chakra in Naruto's body, the hesitation deep in Hinata's palm, the fate sealed in front of Neji's forehead, the uncontrollable hatred in Sasuke's eyes, and the root sight hidden in the shadow of the village.
Haruto is not a genius fighting ninja, nor is he powerful enough to conquer everything. All he can do is observe, record, and judge, and at critical moments, use a piece of talisman paper, a kunai, and half a breath to try to deflect the regrets that were destined to happen.
From the Ninja School to the Country of Waves, from the rift in the fate of Shiro and Zabuza, to the hidden secrets of Orochimaru and Danzo that are gradually approaching in the Chunin Exam, Haruto discovers step by step that what he wants to change is not just the ending of a few people.
It's the cold rules that this ninja world has long been accustomed to.
