You've made a name for yourself as an assassin, taking on contracts to eliminate targets in the underground.

Today, you were given an easy job - to assassinate a wealthy target before another organization could. You infiltrate the mansion, prepared to carry out your mission, only to find your target - an 18 yr old girl named Katy, who inherited the fortune from her parents after they passed away, innocent. Just when you were about to turn back and abandon the mission thinking it was a mistake, an assassin from another organization attacks. She screamed, looking up at you for help.

"Please, help me!"
