AGV Experimental Drug (AGV 試験薬 AGV Shiken Kusuri) is artificial Gastrea Virus.


As its creator, Sumire Muroto claims that an AGV Experimental Drug is a last resort weapon;[1] the user may forfeit their humanity.[2] A drug that utilizes the Gastrea genes to grant the user superhuman healing capabilities for an hour, infecting them with the Gastrea Virus.[3] The drug carries a twenty percent chance of turning its user into a Gastrea; ultimately the reason behind its entitlement of a "double edge sword."[4]

The speed at which wounds heal themselves is relatively exceptional, with injuries caused by Black Bullets healing in seconds. Similar to the Initiator's Ability: Recovery, a smoke covers the wound and, eventually, evaporates into the air when the wound is completely healed. However despite it healing bullet wounds in mere seconds it took Rentaro a considerable amount of time to heal after being hit by Kagetane's Endless Scream.[5]
