After Akako and Kaito agreed to cooperate with the experiment, Naruto let them go.
Before letting Kaito leave, however, Naruto gave him a few spoilers.
After all, he would be leaving this world too, so it was better to resolve any lingering regrets.
The spoilers were simple: they concerned Kaito's parents.
Kaito Kuroba's father, Toichi Kuroba, had been the first Kaito Kid. He was later killed while competing with an organization called Zoo for a gemstone.
Although he was supposedly killed, Toichi Kuroba had actually only faked his death.
When Kaito heard that his father had only faked his death, he initially found it hard to believe.
After all... what parents would abandon their sixteen- or seventeen-year-old son by faking their deaths...?
Besides, it seemed no one knew that Kaito Kid was Toichi Kuroba. Never mind anyone else-even he, his own son, had only learned the truth after discovering a secret room at home.
If Shinichi Kudo had known what Kaito was thinking, he would surely have said, "Huh? What a coincidence! I have a pair of unreliable parents just like that!"
"Actually, not only is your father alive, he's still working as a phantom thief!"
"His current alias is every bit as famous as Kaito Kid's. He calls himself Phantom Thief Crow."
Understanding immediately dawned on Kaito.
Phantom Thief Crow had suddenly appeared after Kaito Kid vanished. There were also rumors that Phantom Thief Crow had been investigating the first Kid's cause of death and that Kaito Kid was his friend...
"So Dad has been staging this whole thing himself?"
By now, Kaito Kuroba believed most of Naruto's spoilers. Next... he would go back and ask Uncle Terai for the truth!
He believed... as the person his dad trusted most, Uncle Terai definitely knew about all this.
