Katanagatari Makers Adapt Arms Dealing Manga
Keitarou Takahashi's Jormungand is a sibling of Black Lagoon. Both manga run in Sunday GX. Both feature heavily armed rule breakers, with their own sense of ethics. But rather than the typical guns for hire, Jormungand works from the interesting premise that its protagonists work for a multinational arms dealing corporation.
Keitaro Motonaga (Katanagatari, the Kikaider and Rayearth OVA) directs the anime adaptation from WHITE FOX (Katanagatari). See the latest trailer below:
