Wilmarina Noscrim is one of the heroines featured in Monster Girl Encyclopedia World Guide I: Fallen Maidens. As the strongest hero of Lescatie, she's in possession of the nation's legendary holy sword Olfoyu, as well as being the commander of Lescatie Holy Ice Flower Knight Order. It's noted that during this time, just her fame as the strongest hero is usually enough to get mamono to flee and human nations to surrender when they learn about Wilmarina approaching. Wilmarina is able to utilize ice magic.

A hero belonging to a holy order of knights in the religious kingdom “Lescatie”. She has extraordinary sword and sorcery skills. A compassionate, kind-hearted young girl with a strong sense of justice, her personality is befitting of a hero. She has truly a heroic presence as she goes about saving and guiding the people, and there are many who revere her. The people of the kingdom believe that she will surely destroy the mamono lord and save the world.

Born of a good family, she’s been trained to fight as a servant of the gods since early childhood. Amidst that strict lifestyle, her only diversion was playing with the son of a servant of the Noscrim family, "you"‎ who was her childhood friend. However, her father who was a priest, and the leaders of the holy order of knights didn’t think it was good for her to be with "you" who was lowly, and of no political value. "Your" entire family was fired as servants, and she was forcibly separated from "you". Afterwards, she decided to kill her old self because of this incident. The common-place, cheerful, and brave girl in love disappeared. Instead, the zealous, ideal “hero Wilmarina” who thinks first and foremost about the world which ought to be ruled by the gods and their faithful believers, was born.

As if trying desperately to forget the past, she focused earnestly on heroic deeds, but one day "you" joined as a soldier of the holy order and ended up being reunited with her. In her heart, she was overjoyed with the reunion, but her life was already completely dominated by her father and the order, companions worthy of a hero. Underlings worthy of a hero, servants worthy of a hero, were gathered. The post "you" had, a low-rank soldier who was neither worthy of being a “hero’s” companion, nor worthy of being a hero’s underling, was nowhere around her. Under the order’s management, she was forbidden from approaching “you” on her own. Even if she happened to run into “you” by chance, she could only approach as “Wilmarina the hero.”
