NARUTO: Blood Prison

Naruto is imprisoned in Houzukijou, a detention site known as the Blood Prison, after being apprehended for trying to kill the Raikage and for the deaths of Jounin from Kirigakure and Iwagakure. The facility's overseer, Mui, employs a powerful jutsu that drains strength from the captives. A threat against Naruto's life exists within the prison. He and his allies work to establish his innocence and reveal the underlying facts.
