Anime Profile: Viper GTS

Based on the popular hentai video game series, this anime studies the eternal struggle between good and evil... although it can be hard to distinguish the difference BETWEEN the two in this series.

Three demonic sucumbi... Carrera, her sister Rati, and Mercedes, are competing to find out who can secure the most souls between them. Carrera seems to be succeeding in the souls department, in spite of Mercedes's clumsy attempts. However, when a nerdy boy summons the sexy Carrera, instead of taking his soul, she takes something else... which gets her in trouble with her bosses.

But more trouble is on the way. Three angels, concerned about the loss of souls from possible reincarnation, decide to punish the demon sisters by sending them to Heaven... with a little help from very UN-ANGELIC behavior, and "holy water".
