Bounty hunters are a very special group.
You say they're law-abiding citizens, yet they can whip out a Gatling mortar and go "rat-a-tat" on the street.
You say they break the law,
but this group somehow holds Imperial-issued arrest warrants and can capture or even execute fugitives.
The bounties from the Bounty Hunter Guild often involve criminals whose fate is irrelevant, and they're usually martial artists or extraordinaries who pose a tremendous threat to the public.
So handling battles involving bounty hunters in the city really tests the investigator's skills.
"Ladies and gentlemen, we were handling a group of fugitives and unexpectedly encountered members of an evil secret organization.
We resorted to using weapons of mass destruction without prior permission, and we ask for your forgiveness.
No ordinary people have been accidentally injured so far.
We are willing to compensate for any loss caused and take full responsibility."
