Crossbone Tanteidan

That's right, don't worry–please put your minds at ease. We are this suburb's own detective agency. No matter how small the matter, our company president will personally direct every operation. You won't have to worry about the clean-up either. We'll take care of it ourselves, because… we are the Crossbone's Detectives, and that's just how we do things.

Also includes "Scramble Fish" oneshot.
