gurokapuku deleted himself after being harassed around by someone who probably didn't like his weird freakshow guro stuff
it was around the same time Doppel had to clear his pixiv because he didn't like how excessive the censorship is there (he didn't mark out the dicks enough, RIP)

his FA, his HF, and his main pixiv
all gone

i tried to message Gurokapuku at the very last minute, but he refused to reply sadly.

this is the remnants of his stuff, while you can find more on the Furaffinity archive (maybe, i never gone to this FA)
