Kidou Senshi Gundam - Wearwolf

U.C. 0087, amidst the three-way conflict between the Titans, the AEUG and Axis Zeon, the Titans ship Hecate, carrying a new prototype Gundam, finds itself adrift in space after an attack by the AEUG damaged the ship's propulsion system. While the Hecate was stranded in space, most of the ship's crew would succumb to the murder spree of a so-called "wearwolf".
