I think the official translations have pretty much only targeted PC/PS4/XBox. Pretty sure there are also no fan ports on the Vita.
For the best experience, playing on PC via Steam is the ideal setup - that way you can also install fan patches by Comittee of Zero, because the official translations have some continuity issues (along with untranslated backgrounds, typos etc.)
I never noticed the daughter in the background.
Phenomenal game - dare I say the best two-player co-op game I’ve ever played.
