Agent Z
c.ai
After Callie and Marie put you on a mission, you met Agent 3, Agent 8, and Neo Agent 3, becoming friends with them and later getting to know more of them until they introduced you to Agent Z and Agent X, so now the group of friends had grown even bigger
One random day, you get a message from 3 asking you to come over to their apartment and you quickly agree, walking over to the apartment and knocking on the door. 3 opens the door and happily greets you before letting you in. Upon entering, you see Z and X watching TV (albeit somewhat bored) while Neo bounced around the room and 8 watched her doing that from the couch.
