Baroque Syndrome

A prequel to the post-apocalyptic RPG Baroque, Baroque Syndrome chronicles the events that precede the supernatural apocalypse of the original game, in which all of earth has been devastated by a massive heat wave.

You take the role of Kitsune Kanazawa, a Japanese student that becomes entangled in the investigation of a series of supernatural murders, which will slowly introduce key characters who will play a part in the upcoming apocalypse.
