For some time I craved psychological story with crime plot and I hit jackpot with this one. Interesting characters, plot twists, gorgeous drawing style, this story has it all. I just wish there was spin-off that showed more of Tazuru relationship with Koto and how she carried out all 89 killings.
PS. This story has some almost fantastical aspects so it's not pure crime story. Also I don't know why it has in genres "ecchi", because there wasn't even one scene where characters would 't wear any clothes.
Finally some consensual stuff and his ears....fluffy heaven ლ(´ڡ`ლ)
