Description
Erica Blandelli is a central figure in the story, introduced as a sixteen-year-old mage from a prestigious family in Milan, Italy. She is a knight of the Copper-Black Cross, a powerful magic society, where she holds the high rank of Great Knight. Her reputation precedes her, earning her the nickname "Red Devil" or "Crimson Devil" due to her formidable skills and personality. Physically, she is a beautiful young woman with long, straight blonde hair with a hint of red and striking blue eyes, possessing a tall, slender yet voluptuous build that is often noted by other characters.

Her personality is a complex mix of aristocratic confidence and fiery passion. She is courageous and strong-willed, showing no fear even when confronting heretical gods. As a noble from a distinguished family, she possesses a great deal of pride and can come across as arrogant and manipulative, with a sharp tongue and a talent for pushing people's buttons. This devilish and teasing nature is well-known among her close associates, who sometimes call her a fox or a lioness. However, underneath this confident exterior is a side she shows to few: she is surprisingly lazy when not working, with a habit of oversleeping and being petulant when woken. She is also a glutton, capable of eating large quantities of food, especially if she enjoys it.

Erica plays an absolutely pivotal role in the story, as she is the primary catalyst for the protagonist's transformation. She is the one who involves him in the world of gods and mages, leading directly to him becoming a Campione, a god-slayer. Following this event, she becomes his first and most prominent companion, swearing loyalty to him as her "master" and declaring herself his "sword and shield." She sees herself as his number one, often referring to herself as his "lover" or "first mistress." Beyond the battlefield, Erica acts as the leader and strategist of his group. She is highly intelligent and a skilled tactician, managing his relationships with various other magic organizations and acting as his unofficial diplomat and public relations expert.

Her key relationships define much of her character arc. Her bond with the protagonist is the most significant, evolving from initial mockery and antagonism to deep love and unwavering loyalty. She is possessive of him but, after some initial resistance, becomes surprisingly willing to share his affection with other women who join their group, as long as she remains first in his heart. This leads to a close, though competitive, friendship with the shrine maiden Yuri Mariya, whom she considers a friendly rival. Her oldest and most complex relationship is with Liliana Kranjcar, a knight from the rival Bronze Black Cross society. They have been friends and rivals since the age of two, growing up together and constantly pushing each other to improve, despite having opposite personalities. Erica's uncle, Paolo Blandelli, is the head of the Copper-Black Cross and the only person she truly listens to, acting as her guardian and father figure.

Throughout the story, Erica undergoes noticeable development. Her pride makes her reluctant to initially admit her feelings for the protagonist, but once she does, she becomes extremely forward and honest about her love, a stark contrast to her earlier, more arrogant demeanor. She grows from a self-centered individual, concerned with her own reputation, into a dedicated partner who prioritizes her king and is willing to sacrifice her standing within her own organization for him. She matures into a supportive figure, sometimes even acting as a guide or older sister to the other girls who join their group.

As a mage, Erica is a disciple of the Hermetic tradition, with her magical specialty being the manipulation of iron, an art known as炼铁术. Her primary weapon is a magical sword named Cuore di Leone, which means "Heart of the Lion." This blade is almost indestructible and can repair itself from any damage, even from fragments. She can also reshape the sword into other forms, such as a chain or a spear. Her most powerful spell is the Golgotha, a terrifying curse that evokes the final words and agony of Jesus Christ on the cross. By chanting these words, she can transform her sword into the Holy Lance of Longinus, a weapon powerful enough to wound even a god. When empowered by the protagonist's authority, she can also don a full-body magical armor that turns her sword into a large lance and shield for close-quarters combat.
