i confused what he meant by disappear? i understand the end of sentence since this manga is about that but it is me who does not understand clearly what he meant at start or it is the translation?
it is me or is the translation is making no sense at the end? keep the "promise"? what promise? that he should throw away his badge to fight him? what?

We know it is yours but not those who look at those other sites (or so i think if they delete your info)
