My Younger Sister is My Roommate! [v1.0] By OMNC

OMNC released a new game called My Younger Sister is My Roommate! and the version is 1.0. The game’s story is about After a water pipe broke at her dormitory, Yui came to stay at my place until the repairs were finished. It’s been years since I last saw my younger sister, and she’s quite cold—not to mention completely unreserved with me, her older brother.
