Kuro no Orpheus

A student working the midnight shift, part-time, as a security guard at the number 1 women's dormitory of Holy Orpheus School for Women. Needless to say, the dormitory is full of young nubile women, and many of them have recently returned from living abroad; the atmosphere within the dorm is decidedly lively. Hey, this situation looks very promising. But once the actual work begins, our hero has to deal with problem students that do not follow the rules, students that hate men, strange students engrossed in suspicious rituals, and others like them that cannot be easily dealt with in the conventional way. Despite all this, the students are all extremely beautiful, and can you blame him that he tries anything and everything to become friendly with them? At first, he works to develop some intimacy with the girls, but then, things turn upside down, and the situation progresses to the point where he is in the position of protecting them. Think of a way to protect the girls from the devilish plan of targeting these girls by drawing out and discovering their hidden innermost feelings. As the plot within the school thickens and things gradually transpire, will you be able to protect the girls without succumbing to the great, yet unknown powers?
