Now enrolled against her will at an isolated girl's academy, Mari is unaware that hidden eyes are watching her, waiting for her memory to return. Buried in her psyche is the most terrifying secret of all: while Mari was the only human who lived, she may not have been the only survivor! As something in a female skin invades Kaihou Academy, Mari's only hope may lie in a strange girl to whom she is inexplicably drawn yet cannot trust. (Source: Sentai Filmworks)

Modern Germany is plagued by an outbreak of "Amalgams." Existing solely to wreak havoc, these cybernetic entities spawn from rotting flesh and can fuse with technology to gain new abilities. With society left in the wake of their destruction, the Xenogenesis Assault Team (XAT) is formed to suppress the threat. Alongside its primary mission to protect against the Amalgam attacks, the organization is also researching the newly discovered "amalgamated" humans which possess rational thought and are far deadlier than their non-sentient counterparts. Joseph Jobson is one such amalgamated human who has full control over his powers. Although successful in his line of work as a lone warrior, an unfortunate encounter with the recently-turned-Amalgam Gerd Frentzen makes him a priority target of the XAT. As he eludes the organization and seeks new allies, Joseph is transformed into the Blassreiter—a being heralded as the strongest Amalgam in existence. Now, he must fight back with his newfound powers to uncover the truth behind not only his past, but also the entire Amalgam conflict. [Written by MAL Rewrite]
