Interesting... this seal! As the Sealing Jutsu Formula version of the "Caged Bird Seal" took shape within the tactile perception of his Chakra, Chiba's grim face almost seemed to radiate killing intent.
Yukina blurted out in alarm, "Chiba!"
"No, I'm fine."
Hearing the alarm and doubt in Yukina's voice, Chiba loosened his hand and hurriedly spoke. The killing intent faded in an instant.
There was no way to remove this seal at all! Moreover, its tendrils extended through most of the brain's nerves, completely controlling the life and death of whoever bore it.
The only way to undo this seal was for the person marked with it to die!
Yet as he spoke, blazing fury surged within him.
Just now, he had been extremely careful not to let his Chakra trigger the seal's activation mechanism and cause it to activate. But now that the seal's patterns had been constructed as a Sealing Jutsu Formula, Chiba realized that he had not needed to be so cautious at all.
This seal was incredibly stable. His Chakra could not possibly activate it. This Caged Bird Seal would only react to a specific kind of Chakra—the Chakra produced by the secret Caged Bird Seal activation formula passed down through the Hyuga Main Family.
And it could only be activated by a member of the Hyuga Main Family.
That was because this Caged Bird Seal was entirely composed of a special Chakra of the same type. It would not react to any other kind of Chakra.
But precisely because of that, the Hyuga Clan could use the Caged Bird Seal to control the branch family and turn them into their loyal protectors. If anyone who knew the activation hand seal could trigger it, it would be a miracle if the Hyuga Clan had survived for
