This one is old style Kago, with a simple conceit and pretty realistic and grisly gore, like The Savage Mouth by Sakyo Komatsu or Chuck Palahniuk's Guts. As Rizzah explains it,
The Collection is a fucked-up story of one girl’s obsession with a dude. She collects everything he touches… EVERYTHING. Very NSFW, NSIFOYGF, and NSIFOYMAD (try to figure out those last two!).
