The existence of Lightning Blade: Fang meant "icing on the cake" to Uchiha Izumi.
After all, Uchiha Izumi's strength had already reached the Elite Jonin level.
This icing-on-the-cake gift.
Would not slow down Uchiha Izumi's rate of progress.
Nor would it make her dependent on the broken blade.
In Elite Jonin-level battles.
The broken blade's existence was no longer lethal enough.
So its existence was more like an auxiliary ability.
At certain times, it could restrain the Aburame Clan.
Or ensure that she would not be absurdly killed by a small Kunai flying at her.
Although the anticipated awakening of her eyes would bring forth Susanoo.
Susanoo was not something that could be used casually, either.
It came at a price.
What was truly heartbreaking was... Uchiha Izumi's genes were incompatible with Wood Release Cells.
Unlike Hatake Kakashi, whose compatibility had reached over ninety-five percent.
This meant that Uchiha Izumi had no way to use Wood Release Cells to nourish her Eye Power.
The Great Electrifier could replace Susanoo and block weaker attacks in many situations.
Besides...
The more important reason Hyuga Sho had embedded the broken blade into Uchiha Izumi's body was...
This was part of his plan to raise her favorability toward him.
Judging from Uchiha Izumi's misunderstanding before the transplantation, when she had seemed ready to let him do whatever he wanted, it was clear that her favorability had already exploded.
Next.
Hyuga Sho planned to raise Uchiha Izumi's favorability to an even higher level.
He would make her body and soul... both become his possessions.
"Izumi, don't move."
After a round of sparring.
Uchiha Izumi maintained the Great Electrifier's stance, her entire body bathed in white lightning.
Then.
Hyuga Sho himself also used the Great Electrifier.
Thus.
