A 7-minute long "White Day Movie" for the upcoming PSP visual novel Dies irae: Amantes amentes, releasing in Japan on June 28, 2012. This PSP port is based on the surreal eroge Dies irae: Also sprach Zarathustra (Day of Wrath: Thus Spoke Zarathustra), originally released by studio Light in December 2007, and its later remake and expansion from 2009. The title itself is a mix between the medieval Latin hymn "Dies Irae" about the day of judgement, and the books "Also sprach Zarathustra" by German philosopher Friedrich Nietzsche. The game's protagonist is Ren, a student who was hospitalized for two months after an epic battle against Shirou. After he leaves the hospital to try and start a new life, he has a dream of a guillotine, a murderer who chops off someone's head, and the knights who chase him. Eventually, Ren crosses over the boundary between ordinary life and extraordinary life.
