The year is 22XX, the world civilization collapsed due to the lack of power after the explosion of a nuclear reactor. You are cast in a role of Lau, main protagonist whose character is modeled after the J-POP singer Gackt. However, your friend Lei turned on the dark side and is set to destroy what is left of the world and your plan is to stop Lei by any means necessary. The entire gameplay is very similar to that of Devil May Cry games, you can jump off the walls, performs various sword attacks, and use special magic attacks while battling the minions of darkness.
Believe it or not but there is this huge controversy over if the main character Lau, modeled after the Japanese pop singer Gackt Camui, is a man or a woman. Many people say man obviously for his voice and his name. Others say woman because of his looks. In the end, Lau is really a man.
