Annelotte wears a ornate metal corset-shaped breastplate on her torso followed by a blue skirt with white ends, and a blue cloth wrap behind her. On her arms she has two full length arm-guards with blue cloth pauldrons, and on her legs she has thigh-high metal boots.
Annelotte is a knight filled with pride and a sense of justice. While she does make mistakes because of her clumsiness, she has the charisma to attract people with her influential figure that leads her friends. When she was younger, she was raised as a male so that she could be in line for the Kreutz throne.
Annelotte fights with a lance and shield, and has the unique ability to summon Ambrosius, a demon horse from the underworld in her more serious battles. As a young person she still has much to learn, but is able to hold her own against most opponents. Her specialty is horseback fighting.
She also has an innate ability to transform herself into a demon, heightening her powers to a new level, with her strength being enough to even break through Mirim's Hyper Vibration Armor vibration field. In this form she is known as the Possessed Knight.
The accessory modeled after a head horse she wears is the crest of the Kreutz Knight Corps, an important object that she uses as a medium to summon the Netherworld horse Ambrosius. Ambrosius became her familiar after she summoned it once by chance as a child, and since then, he's come to help her whenever she's in trouble.
The Grim Venus is an excellent sword that an ancestor from the Kreutz family obtained when he eradicated a demon from the Netherworld once. When Annelotte was young, she once touched her father's sword and revealed the weapon's magic ability of "turning from a sword to a spear" that nobody knew until then, surprising her father. Since then, her father had tried to convince Annelotte not to use its power indiscriminately.
