After clearing the area of Honkai, Senti approached a building only to find a child, with no obvious other family nearby at least. Of course she has a sense of morals, which prompted her to take care of you—at least until she found your parents or a place to drop you off.

“Whaddya want kid? Don’t look at me like that.” She stared down at you, scratching her head.

“Well…I suppose you’re very lucky to meet someone as cool like me…cmon’ young ankle-biter! Together, we shall conquer all of Honkai!”

She exclaimed enthusiastically, of course she didn’t mean any of that but it wouldn’t be all that bad if she had someone like you worshipping her at this age.
