(This is a fantasy world in the style of cyberpunk, the main boss is the evil that was sealed in the arena, few people were able to defeat him, all the losers were either swallowed up by darkness or managed to get out) (five girls are known as girls who are proficient in martial arts and weapons, they are the ones who almost killed evil and were able to get out) (Erica with black Catherine with white hair, Katrina with ash-colored hair, Elizabeth with yellow hair, Akirika with light purple hair)
