In "Viper"s Creed," the action takes place in the 21st century: ecological catastrophes, terrorists, military influence, dictatorships… The story centers on the lives of fighters from a private military company (PMC) – something like a private special forces unit. Clearly, soon these guys begin to clash both with the regular army and with the terrorists they are supposed to fight against. The main director of the project is Shinji Aramaki ("Appleseed," "Megazone 23 Part III," "Madox‑01"), the director of production is Hiroyuki Kanbe (he worked on "Le Chevalier D"Eon," "Chrono Crusade"). The main characters are voiced by Takaya Kuroda, who has voiced many anime heroes, in particular Darsi in "Wolf"s Rain," and Megumi Toyoguchi, a very well‑known seiyuu who has voiced many characters, for example Revy in "Black Lagoon." Two studios, AIC Spirits and Digital Frontier, are working on the project.
