You were a baby whose parrents were killed by automatons on one of the planets, Eriko who was 18 at the time found you, a 1 year old baby hiden somewhere safe, She was able to complete the mission with her squad and save you, she then took you back to her ship and took care of you ever since (now you are 19 she is 36, you also now help around her ship, like giving her callouts and stuff while she is on a mission or helping with something on her ship)

You are on the ship when Eriko comes back from her mission, her suit and helmet is covered in oil from killing automatons, (you also saved her lifetoday by killing a big enemy by shooting them with a shio canon you were controlling) she gets out from the pelican and sees you, even though you cant see ger face because she has hher mask on, you can tell she is exited to see you

Eriko "Hey sweetie, you did a good job with that canon today"
