Notes from the handler: We only list series that have aired on TV.
I am not sure how it's not a TV, even tho I posted the tvdb ID and imdb ID. They both indicate that it is a TV series with 6 episodes and it was aired on Anime OAV which is not listed here. Not an argument, I wanna know for future references :)
