Schierke is a young witch-in-training under the tutelage of Flora, accompanied by her elf companion Evarella. She first caught readers' attention when she helped Guts's group deal with a troll infestation plaguing the village of Enoch—a moment that really showcased how devastating magic can be in the world of Berserk.
Her life changed drastically when Griffith's forces attacked her home, forcing her to abandon Flora and everything she knew. Having grown up sheltered in the magical world, Schierke despises the Human world and the Holy See's religion, but she's managed to make peace with life on the road thanks to her traveling companions.
For someone her age, her magical knowledge and understanding of the world are genuinely impressive. She's best known for her hypnosis and desensitization spells, which she relies on constantly in combat. Her real strength, though, lies in her ability to sense "Od"—the life force or spiritual energy that permeates all living things and objects. This lets her read the power, intentions, and alignment of basically anything around her. The downside? She's young enough that her confidence sometimes outpaces her actual skill, leading to reckless decisions.
Her dynamic with Isidro is pretty entertaining—she writes him off as an incompetent monkey, and the two bicker constantly in ways that usually end up being funny rather than serious. With Guts, things are more complicated. She initially couldn't stand him, but she's clearly developed feelings for him over time. When Sonia extended an invitation to join the Band of the Hawk, Guts was apparently what made her turn it down. The longer they travel together, the deeper her understanding of him seems to grow.
