"Sky Dance Technique!"
After leaving the school, Hawking used the Disillusionment Charm to turn invisible, then flew toward Ichigo Kurosaki's home using the Sky Dance Technique.
So this was Ichigo Kurosaki's mother, Masaki Kurosaki?
Upon arriving at Ichigo Kurosaki's home, Hawking looked at the large photograph hanging on the living room wall. It did not resemble a memorial portrait so much as a poster. He activated the Eye Power of his Rinnegan.
"Rinne Rebirth!"
A moment later, nothing happened.
Just as I thought. There was no way to revive her.
Masaki Kurosaki had originally been one of the Pure-blood Quincies. When she saved the Shinigami Isshin Shiba, she had been bitten by a Hollow. Her body became mixed with Hollow Power, tainting her bloodline. Yhwach, the progenitor of the Quincy, took away her power, and she eventually died at the hands of a Hollow.
That was also why Ichigo Kurosaki possessed four kinds of power within him.
His Shinigami Power came from his father, Isshin Shiba. The Shiba Clan had once been one of the Five Great Noble Clans of the Bleach World.
His Quincy Power came from his mother, Masaki Kurosaki, who had once been a Pure-blood Quincy.
His Hollow Power came from the Vasto Lorde that had bitten his mother, a creature modified by Aizen.
As for his Fullbring Power, humans who survived being attacked by Hollows could awaken Fullbring Power after having children.
Since Masaki Kurosaki had ultimately died at the hands of a Hollow, even her soul was gone. Thus, even if he used Rinne Rebirth, he could not bring her back to life.
Rinne Rebirth could revive the dead, but only if the deceased's soul still existed. Even if it had merged into the world itself, like in the Harry Potter World, it at least
