Long before Harry Potter, and the wizarding world was ever a thing there existed Vanillaware's, "GrimGrimoire". A PS2 era tower defense and resource management game centered around a student named Lillet Blan, and a school for magicians known as the Silver Star. Much Like Harry Potter's own misadventures, Lillet Blan also found herself as the chosen one amidst a sinister plot to resurrect the infamous school's Archmage, and his army of demons.
Lillet enters the school as a fledgling apprentice eager to learn, and do right by her brothers. She meets her would be teachers at Silver Star, and in turn begins her studies of grimoires, and the ability to summon familiars of varying types using mana. First meeting with the elder headmaster then a devil, a cursed beast, and a necromancy professor before butting heads with the unleashed Archmage himself. Setting into motion a groundhogs' day worth of repeated encounters slowly helping Lillet and her trusted acquaintances find out the who, what, when, where, and why of the perplexing situation. Enabling Lillet to grow in power as she does what needs to be done to save the day.
