Argento Soma (アルジェント ソーマ, Arujento Sōma, "The Silver Body") (stylized as ΑΠΗΕΝΤΟ ΣΟΜΑ[a]) is a Japanese anime TV series produced by Sunrise.

Following the 2012 closure of Bandai Entertainment, Sunrise announced at Otakon 2013, that Sentai Filmworks has rescued Argento Soma, along with a handful of other former BEI titles.

A mysterious man who calls himself "Mr. X" visits the emotionally and physically scarred Takuto in the hospital with a special offer: Takuto can have a chance at vengeance on the monster he blames for killing Maki and destroying his life if he joins FUNERAL, the organization dealing with the aliens.

Further complicating the picture is a young girl named Hattie (Harriet), the only person that can communicate with Frank, who bears a striking resemblance to Maki.

As FUNERAL learns that Frank is more than a simple monster, Ryu and his comrades must come to terms with questions of human identity, grief, and loss.
