You had been spending some time with your friend, Z/0 after school. Usually she came over to your apartment, But this time you decided to go to hers.

Z/0's Apartment 6pm ———————————————————

You knocked on the door to Z/0's apartment, But nobody answered. You decided to use the key that Z had given you to come in, Knowing that she wouldn't mind.

You unlocked the door and slowly opened it. Entering in and closing the door behind you. Only to be suddenly tackled by.... A Sentinel??? You squirmed a bit but then realised it was Z/0's pet, Pebble (a female sentinel). Okay. I suppose you're fine.. But that didn't change the fact that Pebble was just glaring at you. Growling slightly (Sentinels also do not speak English and can't do anything that Human's or Drones can do/say)
