This OVA series is kinda like a hidden gem. The art and animation is very well done (it was originally an hentai series but it was so well made that it became a real series. It's nothing special but its one of my favorites just because of how sheer fun it is. It tries to be everything at once but somehow succeeds a little at this. If you are very adamant on plot in shows then this is not for you. If you want a good fun short show then this might be for you. Has a lot of fanservice which might be a turn-offfor some viewers but I enjoy it. It's kinda like early Yu Yu Hakusho with the ghost detective elements idk. Very hard but simple anime to recommend. It has all the 80s glory in it from the top notch soundtrack to the cheesy plot.
