Quests

Ok, so the clue states:
"Those in power tend to not like pirates. Find this group that run things in One Piece, and who they use to catch Luffy's crew."

I was able to figure out the group, but I an still stuck on who they used. I thought it was a certain little birdie, but going to her page didn't win the quest.
Did I not figure that out correctly or have I come across a bug?

If I am wrong, could someone please drop a hint because I am stumped...
Thank you!

it is simple for someone who has seen the whole thing. not so much for someone who watched it occasionally more than five years ago.
based on what i found online on other sites about this particular arc, i figured the capture of nico robin drawing in luffy and his crew would be the answer. apparently not...
checking all the people connected to the government page didn't help either.
