The White Demon Lord plots to eliminate Arata and the Trinity Seven to usurp the position of Demon Lord.
The official website for Trinity Seven: Eternal Library & Alchemic Girl (Gekijōban Trinity Seven – Yūkyū Toshokan to Renkinjutsu Shōjo), the upcoming anime film of Kenji Saito and Akinari Nao’s Trinity Seven – The Seven Magicians manga, announced on Saturday that the musical duo Polka Dots will perform the insert song “Lost Days -Piano ver.-.”
Bristling with untold power, the White Demon Lord attacks Arata, and triggers a desperate crisis where Arata and the Trinity Seven must save the world in this last battle.
The anime film’s voice actors and staff will appear at special events for seven consecutive days beginning on Monday.
