Age: Deceased (died at age 18) Yuusuke was Haruto's childhood friend and Asuka's older brother. He was involved in the process of completing the planning for a film he thought of when he died in an accident one year prior to the events of the game. Yuusuke always talked like a theorist and he was the centerpiece of Haruto's group of friends. [Translated from the official site and partly taken from MAL.]
