Find your perfect sadistic girlfriend in this unique bishoujo game from Genius Studio Japan!


After living alone with your dad for the past ten years, he has some news—he’s getting married and you’re getting a stepsister! Fortunately, it turns out that she’s one of the kindest girls in your school… or so you thought. Turns out she’s a sadistic bully, and now she’s blackmailing you! Will you be able to keep this secret from your best friend and the classmate you’re ordered to spy on?

How will you navigate your new life with a sadistic sister?

Find out in My Sweet Sadistic Sister!



Reika is one of the most popular girls in school and the top of the class. When you find out she is going to be your new stepsister, you can’t imagine anything going wrong. But once you get to know her, you realize her persona at school is a sham. The Reika at home is sadistic and cruel. Can you save her from herself?


Seri has been your best friend for years. Though she’s usually busy playing whatever sport is in season, she prefers to spend her time with you at the arcade, where she holds all the high scores. As you try to protect her from Reika, you realize your feelings for her may run deeper than just friendship…


Yoshiko is a sweet, quiet classmate who you’ve recently become friends with. She can always be caught in the courtyard reading, and the two of you bond over your love of books. Problem is, Reika has tasked you with spying on her, but the more time you spend with Yoshiko, the closer you become…
