Had seen it floating around, on social media groups
Connections i found those given for it:
-Both are incredibly skilled and deadly female assassins from critically acclaimed anime/manga series who, through various circumstances, ended up taking the role of a domestic house worker, trying (and failing) to keep their identities and brutal professions a secret from their loved ones.
-Both adopt rather amicable, soft-spoken and caring (if not slightly cumbersome) demeanors around their peers, contrast to their ruthless and almost mechanical personas when acting out their expertise in murder.
-Both were thrusted into their current occupations (as a housewife and a maid, respectively) as a means to their own ends (so Yor could continue her job as a contract killer and not get accused of being a spy, and for Roberta to escape her seemingly never-ending conflict as a soldier) but came to truly commit and value their new roles, growing especially close with a young child (Anya and Garcia) who learns of their bloodstained pasts but still loves them for who they are. Both are noted to also be rather unskilled in their duties (both being notoriously bad cooks) but nonetheless stick to them and take it upon themselves to treat them seriously.
-Their bloodstained reputation amongst their fields of work earned them specific monikers related to their fighting styles/methods of killing (Thorn Princess and The Bloodhound). They're also noted to be unusually strong within their own verses despite being otherwise regular humans.
