Hoshino Yu transmigrated into the world of Naruto, only to discover that he had three Cursed Seals in his body!
The first Cursed Seal: Hoshino Yu's father was a spy for the Hidden Cloud Village. After Danzo of the Hidden Leaf Village discovered him and had him executed, Danzo planted the “Root Cursed Seal” on young Hoshino Yu to control him.
The second Cursed Seal: Obsessed with research and eager to find more “test subjects,” Orochimaru planted the “Snake Cursed Seal” on many people in the Hidden Leaf Village. He did it both to control those marked by the seal and to keep the village from discovering his experiments. The unlucky Hoshino Yu was among them.
And on top of that, Hoshino Yu had a third Cursed Seal...
And so Hoshino Yu went on to enjoy a happy life as a triple agent.
