Eternal Sex 2 :

It's been a week since the city of San tag Rae fell, over ran with demons. Right in the center is a gloomy looking castle now, where the demon queen resides , most of the time. The country has went into a s tate panic in nearby areas, for the demons have started leaving the City, now known as Sin City. The army., proving to be insufficient at droping them, has went to hiring specialists, known only as the D.S.A. It's a secret organization that the current president started, before he was president.

Most likely theirs no humans left in the city, but they have to be sure. They send a team of three in at night fall, on the president's orders. As for the nearby towns, they send the D.S.A. to protect the citizens, hopefully, as the corruption has begun consuming nearby areas into the demon queens new domain.

Waves of demons leave the city every 3 days. The waves consist of about 8 demons. One per direction each time, about three times on the day.
