Blood is a Fenrir special forces unit formed by Dr. Rachel Claudius. It consists of Julius Visconti, Ciel Alencon, Gilbert McLane, Romeo Leoni, Nana Kazuki, and the protagonist. Those chosen to Blood have the confirmed potential to awaken the "Power of Blood" and to the usage of Blood Arts. All Blood members are 3rd generation God Eaters. Also, Blood members differ from regular God Eaters in that their God Arcs respond normally when facing Invasive species (like Marduk). Regular God Eaters will experience no response from their God Arcs when facing Invasive species alone.
