Trinity Seven: Eternity Library & Alchemic Girl

Arata accidentally touches "Hermes Apocrypha," a grimoire belonging to Lilith, and is engulfed in a blinding white light. A girl named Lilim appears before him, referring to both Arata and Lilith as her parents. Her arrival triggers a shift in the world-the forbidden Eternal Library awakens. Inside it lies the White Demon Lord, the pinnacle of alchemy, now freed from its seal. Seeking to overthrow the current Demon Lord, the White Demon Lord sets its sights on Arata and the Trinity Seven. With overwhelming power, it launches an assault, forcing Arata and his allies into a final battle to prevent catastrophe.
