Remember this mission done by Kaguya and Inasuke? The badfic slain there is receiving a riffing, but in script-style because the narrative is too tedious for a traditional MST. The script-style is something I learned from Das Sporking, in which the content of the fic is humorously summarized in script format. The riffing is as of yet incomplete and will be updated until it eventually covers the entire fic, but for now the first 6 chapters are done. You can read it and check back for updates here, but be warned of swearing, both in-fic and in the riff because the fic disturbs and angers me at times, and constant references to and trivialization of senseless murder.
