It is more like a re-written work than translation, especially the last part. Carerra is the short hair one, Mel is the long hair one. Neither of the demon girls’ name is Ogawa. Ogawa is the main character in the original game:VIPER GTS. In this manga, he and Latini (a pink haired demon girl, who is the youngest of the three demon girls) didn’t show up their true form, because they were transformed into that double headed dildo by Carerra cause she wanted to surprise Mel. They did surprise Mel at the end of Manga, though Mel have a crazy idea in the bonus page. She wanted to be the double headed dildo in the next round. Carerra agreed with her, and Ogawa had a really bad feeling because they were going to fuck his ass.
