Description
Isolde is a Holy Knight of the kingdom of Liones and a prominent member of the Tristan Platoon, the group of knights serving directly under Prince Tristan Liones. She is a young woman of significant stature, standing at 195 centimeters tall, with long pink hair that reaches her waist and bright green eyes. Her typical attire consists of a dress combined with armor, complemented by elements such as gloves, a hairband, and thigh-high boots. While one source suggests her age is 16, she is more commonly described as being 17 years old, a contemporary of the prince she serves.

In terms of personality, Isolde is a highly dedicated knight who takes her duties with great seriousness, showing a fierce resolve to protect the kingdom and its royal family. However, beneath this stoic exterior lies a much more emotional and vulnerable individual. She is deeply insecure about her own attractiveness as a woman, a feeling that stems from her exceptional height, which was a source of teasing and mockery from others during her youth. This insecurity contributes to a critical self-perception and a low opinion of her own feminine appeal. Her emotional nature frequently comes to the surface, as she is prone to breaking down in tears when overwhelmed, such as when she was questioned about her actions by Tristan. The core of her emotional life is her deep and abiding love for Prince Tristan, who holds a unique place in her heart as the only person who never ridiculed her for her height and instead gifted her a ribbon, an object she treasures.

Isolde's motivations are almost entirely intertwined with her feelings for Tristan. Her drive to fight and protect stems from her love for him, and she is capable of converting this powerful emotion directly into magical energy to fuel her abilities in combat. This love transforms her into a fearless fighter against any enemy, yet she simultaneously reveals a shy, girlish demeanor when in Tristan's presence. Her ultimate aspiration is to become Tristan's bride, a dream she has held since childhood. The death of her childhood friend and fellow knight, Jade, who sacrificed himself to protect her, also serves as a profound motivation, instilling in her a sense of guilt and a determination to honor his memory.

Her role in the story is primarily defined by her position within the Tristan Platoon, where she fights alongside Tristan, Chion, and the late Jade. A significant arc in her journey involves a confrontation with Tristan after he is afflicted with amnesia and adopts the persona of Tantris. In a desperate attempt to restore his memories, Isolde engages him in a duel, during which she is stabbed by the confused prince. This act of self-sacrifice proves successful, breaking through his amnesia and restoring his true self. This event marks a pivotal development, as Tristan finally acknowledges his feelings for her, leading to an emotional embrace and a kiss, cementing the romantic nature of their relationship.

Her key relationships define much of her character arc. Her relationship with Tristan is the most central, evolving from her unrequited childhood love to a returned affection that forms the emotional core of her story. She shares a complicated dynamic with her fellow squad member, Chion, who was also part of the group saved by Tristan in their youth. With Gawain, one of the Four Knights of the Apocalypse, Isolde initially gets along well, though she occasionally grows annoyed by Gawain's flirtatious behavior directed at her and other women. Her bond with the commoner knight Anghalhad develops into a close friendship, with the two sharing their romantic thoughts and feelings. Her most tragic relationship is with Jade, who harbored hidden romantic feelings for her. Isolde only begins to realize her own potential feelings for him after his death, adding a layer of tragedy to her character.

Regarding her abilities, Isolde is a capable Holy Knight with a unique form of magic. Her power is explicitly fueled by the love she holds for Tristan, allowing her to draw immense strength from her emotions. In combat, she wields a large mace or a similar throwing weapon as her primary armament, using it to strike at her foes with great force. She has also demonstrated the ability to create explosive effects during battle, showcasing her tactical and magical versatility. Her defining act of courage, however, is not an offensive spell but her willingness to place herself in mortal danger, willingly receiving Tristan's blade in a final, desperate gamble to save him from his own lost memories.
