Guess what will we see in the next chapter:
-Startled Mahiro leaked. (Yeah, Nekotoufu's fetish strikes again)
-Friends come and call her name which made mom notices the truth.
-Mihari had to tell mom the truth, the two are waiting for angry mom's reprimand nervously.
-Mom doesn't get angry, and feel pleased to have a cute daughter.
-Mom knows Chitose, and know exactly what are they reserching.
-Mom agrees to keep the secret, but mentioned Mahiro girl's life won't last forever, let her to think about the future.
-Mom pretends to be concealed, but see through everything, and glad to see Mahiro stepped out from the shadow in an unusual way.

Hope Nekotoufu can bring us something not that cliche in the next month.

If you're saying it because she has a different hair color, she could've easily inherited that from her father or from her grandparents.

not the hair, her general vibe seems completly off compared to the rest of the family we saw so far

Fair I guess. Though to be fair it's only Mahiro and the mother so far, so she still could've taken after her father, if not then I guess we can go with the adopted theory or just black sheep of the family.
