Chloe Maxwell is a main character in the anime, serving as a young Logicalist. She is depicted as a teenage girl with blue eyes and long blond hair that reaches her waist. Her personality is cheerful, bright, and friendly, as she is open and welcoming to everyone she meets. As a Logicalist, Chloe has formed a covenant with Valkyrie, the Goddess of War. During battles, she can enter a Trance state by kissing Valkyrie, an act that transforms her partner into her shield and weapon. In this form, Chloe wields a sword, and she has demonstrated the ability to use two swords simultaneously. She shows a playful and affectionate side, such as when she excitedly complimented Yukari Nanahoshi's braids upon their first meeting. She also values her existing relationships, as shown when she brought her face close to Tamaki Yurine to reassure her that she was the same person she had always known.
