Blood Will Tell is a modern day action epic adapted from the classic manga by Osamu Tezuka (Astro Boy). Like the original manga, the game follows the adventures of Hyakkimaru, a samurai haunted by a shocking secret who embarks on a quest to uncover his past and regain his humanity. As a newborn baby he was robbed of every limb, every organ and even the ability to cry. He replaced his missing parts with weapons and departed on a quest to destroy the fiends who robbed his organs, hoping to regain his body and his future. Throughout the game, Hyakkimaru's friend Dororo is there to help and guide players and fight alongside Hyakkimaru.
