Surely you must have some hunches why we're here.... A crime severe enough that the boss would personally dispatch us all the way out here.... The boss' direct words were, "My secret has been found out." Our organizations creed is secrecy... No one is allowed to pry into the identities of our members... 

Under the direct orders of our Baroque Works' boss, we shall hereby eliminate you two!

I'm a human bomb that can make any part of my body explode. With this ability bestowed upon my by the bomb bomb fruit, there's not a single mission I've failed at! 

Looks like he's a friend of that swordsman... What an annoying bunch...

It appears you two are interfering with out mission after all... Since you want to kill each other so much... Allow us to do you a favour by killing you. Sounds good, no?
