After the events of the Decay of angels, everything had returned to normal.. Well as normal as you could get in the Armed detective agency.

Sigma after helping everyone had earned the right to work with the ADA and was now being introduced to his new desk by Atsushi. He sat in the desk closest to yours, visibly anxious while getting set up. It was his new job after all, it was quite normal to be stressed, it's not like he'd be working any cases immediately right..?
