Schierke has dark green hair and is slim and small in stature, standing at roughly the same height as Isidro. Her regular attire consists of a robe and a typical witch's hat – both purple in coloration. Although these items of clothing cause her to stand out in a crowd, she prefers them over anything else, as they were hand-made and given to her by her mistress, Flora, and serve as a memento of her. In addition, Schierke has stated that she performs her magic best when wearing her witch garbs. Usually, she carries a wooden staff which spirals towards the top, curling around completely at the end. Her shoes and her bag, which is slung over her shoulder, match the colour of her staff. She is accompanied by an Elf - Ivalera - who usually sits atop her hat.
Schierke is mature for her age, quiet, and withdrawn. As a disciple, she was very respectful towards her mistress and was deeply saddened upon her demise. Presently, she gets along well with most of Guts' party, as well as with total strangers such as Sonia and Isma. As a result of being rather sheltered throughout her childhood, she is disdainful towards the human world and the Holy See's religion, but finds life outside of the forest bearable while travelling with her companions.
Although kind and usually friendly, she sees Isidro as an incompetent monkey and regularly mocks his intelligence, causing some friction between the two which frequently lends itself to comical situations. Initially, Schierke held a disliking for Guts, however this was largely due to her not understanding him. She has since developed an infatuation with him akin to a schoolgirl crush, although their relationship more closely resembles that of a father and daughter.
Guts is protective of Schierke, and the young girl recognizes this. When Schierke's garments are sullied by an intoxicated man during their brief stay at a nearby bar, Guts punishes him for "dirtying his girl's new clothes," and when Sonia extends an offer to join the Neo Band of the Hawk, Schierke thinks of Guts before declining. Furthermore, Schierke is the only person to consistently succeed in bringing Guts out of the berserker trance induced by the Berserker Armor, but she herself notes that the danger and difficulty of achieving this will undoubtedly increase should Guts continue to rely on it. When Roderick asks Guts if Casca is his woman, Schierke hears the answer and feels uneasy. Nevertheless, Schierke recognizes that she has something with him that no-one else does; only she can keep him sane under the influence of the Berserker Armor.
Her full story unknown, Schierke spent most of her life in the forest under Flora's tutelage. As shown in the 2016 anime, Schierke sensed the spiritual disturbances caused during the fifth Eclipse and then the Incarnation Ceremony years later.

Having observed the actions of Griffith from afar, Schierke first appears before Guts's group when Farnese and Isidro are ambushed by trolls while finding Casca. Though Schierke did not trust them when they came with Morgan to seek Flora's help, she ends up being sent by her mentor to help them deal with the trolls attacking Enoch Village, giving Guts's allies magical relics to protect themselves. Once at the village, Schierke uses her power to summon the Four Kings of the World to protect the villagers after they take shelter in a Holy See church.
But when Schierke returns to the Mansion of the Spirit Tree, she finds it under attack by the Apostles serving in Griffith's Neo Band of the Hawk. Schierke is forced to leave Flora to her fate to guide Guts to the Berserker Armor her mistress has been preparing for him. When Guts loses control of himself, Schierke astral projects herself into his mind to save him and learns of his pain as consequence. With no home to return to, Schierke remains by Gut's side to help him control the Berserker Armor with her magic.
- Schierke (derived from a word in local German dialect meaning ‘unspoilt wood’ ) is the name of a village located in the Harz Mountain range of Northern Germany. In the present day it is part of the state of Saxony-Anhalt and is now considered part of the town of Wernigerode. Schierke lies below the highest mountain in the region - the Brocken - which for uncounted centuries has been connected to legends and fairy tales concerning witches, devils and other supernatural beings. The summit of the Brocken is held as the traditional place of revelry for witches on Walpurgisnacht - the 30th of April. Modern-day Schierke is host to a festival every year on Walpurgisnacht.
- The name Schierke is a homonymn of Circe, a famous witch from Ancient Greek mythology who was involved in a number of well-known epic tales, most notably The Oddysey.
- Her chants are actual Hermetic incantations of the various Hebrew Kabalistic names of God. Some of her rituals are similar to those in Modern Magick by Donald Michael Kraig.
