"Being out on my own isn't really dangerous. I'm not one of those reckless idiots, and I'm strong enough now. There are very few people in this world who could hurt me. Second Brother, you really don't need to worry so much."
Mousse's voice was calm, but Charlotte Katakuri, who knew his younger brother well, immediately caught the implication behind his words. His face lit up with surprise. "Mousse, can you see the future now? Or has your Devil Fruit ability awakened?"
"Why couldn't it be that I awakened Armament Haki or Conqueror's Haki? Do you have that little faith in me, Second Brother?"
Mousse immediately teased him, but that only made Katakuri more certain that his judgment was right. Sure enough, after the joking died down, Mousse admitted that the Book-Book Fruit had awakened. And he had Doflamingo's spectacular blunder to thank for it. Who knew whether that bastard would be angered back to life if he heard about it underground.
After discovering that part of his memories had been "erased" by the Hobby-Hobby Fruit, Mousse had reasoned that something was off. The memories of everyone in the entire world had been erased for a period of time—what an enormous undertaking that would be.
And it was only temporary. Once the ability user lost consciousness, everything would be restored completely, without any loss?
Could such an incredibly difficult task really be accomplished by the power of a single Devil Fruit?
Thus, Mousse suspected that the memories had not truly been erased, but merely hidden away temporarily. He then used the Book-Book Fruit's memory-management ability to conduct a deep scan, and as a result, discovered a mysterious realm that humans should never have been able to access.
Even Mousse did not dare tamper with the deepest part of his consciousness
