Tsukuyomi-jima is a man-made island on which all the events of Fortissimo take place.


Tsukuyomi-jimi is a fictional island that was and still is the sight for the battles among magi. Twenty-six years prior to the current events of Fortissimo, a war among magi broke out; the war was called Fimbulwinter and it lasted for ten years. The war came to an end when Odin killed Rouge Flame. Over the next sixteen years, Odin gathered OOPArts from around the world and sent them to the island in order to start another war, Ragnarok; in which 12 magi compete for the Ultimate Magic.
