Atarashiku Dekita Onee-san wa, Yuri to Iu no ga Suki Mitai

When their parents suddenly remarried, Haruka and Saori suddenly became sisters. Haruka had already quit her job and was living with her parents, so she thought that Saori, who was cool and focused on her work, lived in a different world... but then she was suggested to live together!

The distance between the two of them grows closer as Haruka helps out her "older sister" Saori with the housework, which she is not good at. Saori, who longs for family ties, also enjoys getting to know her "younger sister".

But Saori has a secret. She is a "real yuri" and has fallen in love with the easygoing Haruka at first sight. If she'll found out, Saori might lose the family bond she has worked so hard to obtain, and Haruka... She can't say it. But she wants to get closer! A certain incident takes a sudden turn in the days of these two step-sisters!?

The girls' love comedy about these two step-sisters begins!
