This work is the first installment of the MURDER MISSION series by Takiya Nozomu! There's 6 in total so far and I've been meaning to track down all of his Nana doujins for some time now and finally got my hands on 2 of them! That now makes 3/6 of the Talentless Nana MURDER MISSION works on e-hentai. Apologies in advance if the title seems wrong!

Also if someone could make a tag for the artist Takiya Nozomumu, the circle Ice-rainy sky and the character Nanao Nakajima that would be great.
