The Pia Eiga Seikatsu website released an exclusive video "interview" with the protagonists of Fullmetal Alchemist: The Sacred Star of Milos, Edward and Alphonse Elric (voiced by Romi Park and Rie Kugimiya, respectively), to commemorate the movie's opening on July 2. The interview stays true to Hiromu Arakawa's manga and anime series by featuring an interviewer who struggles to identify the "Fullmetal Alchemist" at first. Additionally, the video includes appearances from other anime characters as well as three educational "Study" sessions with "Professor" Mustang, who educates Winry and Hawkeye about Creta and Milos.
