Sakura Synchronicity

Sakura Synchronicity is the first game by Whitesoft Albino. Its story starts in April when protagonist Haruka and his younger sister Rise begin their first year at Sotoorihime academy, a school surrounded by beautiful cherry blossoms. Grown up with just the two of them, the two siblings meet new friends and Haruka has another meeting with one of his childhood friends. And then, as if it had simply been waiting for that moment, all of the heroines fall in love with Haruka at the same time (synchronically).
