An orphan who traveled through time to the "roots" of Konoha was planted with the seal of tongue-wielding evil, and his life was hanging by a thread. The protagonist Kei Kawamoto discovers that his soul is fused with the origin of a great fairy. When he transforms into a black cat, he can not only perfectly shield the perception of the curse seal, but also can freely shuttle around any corner of Konoha. He is dormant and dormant. On the surface, he is the most obedient and cold-blooded tool in Danzo's hands. But secretly, he transforms into a black cat. He uses his "golden control" ability to control steel needles as thin as an ox's hair, combined with teleportation in the "space field", to become the most terrifying shadowless assassin in the ninja world. In the process of accumulating trump cards, he met Tiantian, Konoha's "Rich Woman Ninja Tool Master". Tiantian's massive metal ninja tools and his gold-bending skills formed the most terrifying killing combination. He collected Danzo's incriminating evidence, assassinated the top leaders of the Roots, and devoured the laboratory's resources. When Danzo attempted to harvest the fruits and launch a coup on the night of the Uchiha genocide, Kawamoto Kei finally showed his fangs and used the assassination force that Danzo was most proud of to uproot the entire roots and high-level officials of Konoha!
