TRINITY SEVEN

The "Seven Mortal Sins," demons from hell, have pressed forward and have started to spread their plague. Heaven is in chaos, and the angels of the "Seven Heavenly Virtues" are sent to Earth to search for a candidate to become the "true messiah."

The film's story begins when Arata inadvertently touches "Hermes Apocrypha," Lilith's Grimoire. Suddenly, he is enveloped by a bright white light, and a girl appears before him. She calls herself Lilim, and treats both Arata and Lilith as her parents. At the same time she appears, something changes in the world. The forbidden Eternal Library awakens. In the Library is sealed the ultimate culmination of Alchemy, the White Demon Lord. The White Demon Lord plots to eliminate Arata and the Trinity Seven to usurp the position of Demon Lord. 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.

In the story, the prideful archangel Lucifer disobeys God and is cast into the lowest level of hell as a fallen angel. On her way to hell, Lucifer happens to meet a high school girl on Earth named Maria, who helps her. In hell, Lucifer meets Leviathan, and Leviathan explains to Lucifer about The Seven Deadly Sins, the seven demon king rulers of hell. After The Seven Deadly Sins seal Lucifer's powers, Lucifer goes on a journey with Maria and Leviathan to defeat them.

Arata, Lilith and the rest of the Trinity Seven ace off against their greatest enemy; Lilith's own father, who is revealed to be the strongest Demon Lord. He challenges Arata who is now a Demon Lord candidate.
