Variante Vol 02

Following the murder of her family, a girl named Aiko wakes up in a lab to discover that her own arm has been replaced by one from a hideous and powerful monster -- and the arm has a will of its own! Agents from Aethos -- a mysterious, government-linked corporation -- want to use the power of Aiko's demon arm to fight the deadly creatures known as Chimeras, whose attacks on the civilian population are increasing. But Sudo, the agent who has befriended Aiko, isn't so happy about this development. In helping them to defeat this enemy, is she becoming an even greater threat herself?
