Mahou Senshi Louie EP16 - The Conspiracy of the Darkness

Urged by Merrill, the team heads to a ruined estate to search for treasure. There, they meet Isabel and her team. The swordsman, Jakinson, recounts some history to discredit Merrill's claim, but the two teams decide to investigate anyways, hoping to gain some adventure from the outing.They find it in spades. The adventurers fight their way through hordes of monsters to the heart of the ruin's basement, where they discover a farm for magical creatures. The ancient magic, said to be lost ages ago, is very much alive and well--and very deadly.
