Was 11 Eyes the one where the guy is dating Cthulhu and slowly descends into madness/psychosis as a result? Still have a hard time imagining how that turns into a harem thing, but the concept was interesting.

Fun fact:

Harems were more akin to female sweatshops in olden years than sex-oriented. Essentially, if you have laws where "women's purity has to be preserved on pain of death" yet have an need for women to work, you provide a common place for them to work and use eunuchs to carry materials and messages.
It became sexualized with its introduction to western society. I found this out due to looking into eunuch roles.

I was thinking more Ghost Hunt. I may look at Occult Academy. :)
