I get the impression that Chrollo has to decide between a finite number of powers. I'm not sure where or how I got that impression though. I might even be confusing it with other characters from different shows.
no, youre right. i also remember something like "i had to remove one power so i could store this guy´s power". cant say when or where, but it was there.
"She's the only non-loli girl in the show, your honor!" will be my defense in court
