Seijo-sama o Osagashi Deshitara Imouto de Machigai Arimasen. Saa, Douzo Otsure Kudasai, Ima Sugu. - Ch. 1

[FloorRoof]

At first I thought this would be a comedy series about trying to get rid of an overly charitable pest of a sister, but after the other part of chapter it looks a lot like one of those stories about an impoverished saintess who's abused by her fake-saintess sister.

 

[xanon]

It's clear the older sister has the patience of a saint simply because the younger sister is still alive after all the sh*t she's pulled.

 

[AAAAAA413]

Seems like another shallow and irrationally evil villain.
