I was immediately intrigued into the nature of this anime. Sexy girls, guns, supernatural activities?! Who wouldn't be curious?! And i am glad that i gave this anime a shot.
It is extremely well drawn and the plots are second to none. I would place this along the lines of death note (even though i know deep down that it is nowhere that good).
The main person - the seductive detective - is THE person to watch. Sexy, intelligent and very, very naughty, she is truly the perfect main role.
Give this a shot.
