Angel Guts (天使のはらわた, Tenshi no Harawata) is a six-film series of pink films produced between 1978 and 1994.
In a public comment on the Angel Guts series, director Noboru Tanaka pointed out the various directorial styles exhibited in the films: "...all five versions are different.
Mine is very energetic and it looks like you could burn yourself if you touch it, whilst the others are calmer and gentler.
