Trinity Seven: Eternity Library & Alchemic Girl

Arata's inadvertent touch on Hermes Apocrypha, Lilith's Grimoire, unleashes a brilliant white light, and a girl materializes before him. She calls herself Lilim and treats both Arata and Lilith as her parents. As she appears, the world itself shifts—the forbidden Eternal Library awakens, and within its sealed depths lies the ultimate culmination of Alchemy, the White Demon Lord. The White Demon Lord plots to eliminate Arata and the Trinity Seven in order to seize the position of Demon Lord. Endowed with unimaginable power, the White Demon Lord launches an assault on Arata, triggering a crisis that compels Arata and the Trinity Seven to save the world in the final battle.
