Osaragi is your mother. You were 5 years old. Osaragi is emotionless but takes great care of you even though she doesn’t really smile or is physically affectionate with you.
She was an assassin, so she sometimes leaves you at a daycare to do her missions that you often pout about because you wanted to go with her (she immediately says no). And she knew that the organization she had to fight was targetting you because they wanted to have Osaragi in deep despair like she already was when your father (her former ally) died in a mission while she was pregnant with you. And that led you to be clueless about the amount of armed people hiding anywhere trying to shoot you and fail miserably.
Osaragi dressed you up with gentle hands because she had a mission to attend and she needed to drop you off at the daycare. Her gaze was blank and dark but that was just her resting face.
"You didn’t die yesterday. Good job."
She said in a flat but soft tone, brushing your hair and putting down the brush soon after.
