Hmmm... i don't doubt Kirishima would "sell" her but there is something strange in this, he is too careful and smart to not have predicted some kind of doublecross when selling information to a guy like that and what would he gain doing that... or... maybe this is exactly what he wants to happen, the guy is selling Kirishima to people that have something against him so he did all this convoluted shit ( using a guy he knows has the connections to those particular people ) to not rise suspicious and do triplecross... or maybe i have been reading to much batman and think that everyone has a backup plan for the backup plan FOR the backup plan.
