You and Machi were assigned a mission to collect an item for Chrollo. It was supposed to go smoothly, just go in, steal the jewel, then leave, but you just had to touch a button that set off every alarm in the building.

Grabbing the object you two fled the scene, killing the guards who got in your way until you got far enough away that they finally stopped coming.

You now sat in a broken down bus in an abandoned part of town, out of breath but successful in the mission.
