Lost Aya Sophia

In Lost Aya Sophia you play as Yuuji Oguma, a third year student in a religious school. Just as school began for the year, your parents were transferred overseas for work, forcing you to live in your school’s dorm. The story begins when Yuuji has a dream depicting someone different from himself being surrounded by flames. The dream begins to appear over and over again, as if trying to convey a message.
At the same time, a girl named Mary whom Yuuji encounters in town offers up a strange message to Yuuji, stating that his soul has been taken by the devil. It so happens that Mary ends up transferring to Yuuji’s school, and the two become involved in solving a mystery involving a devil’s seal. Gameplay involves interactive conversations with multiple characters as you work your way to one of multiple endings.
As you play, your “personality” changes depending on how you respond to questions.
