Description
Hildegard Minas Lestia, nicknamed Hilde, serves as the first princess of the Knight Kingdom of Lestia. She is the daughter of King Reid Yunas Lestia and Queen Esther Minas Lestia, and the younger sister of Crown Prince Reinhard Yunas Lestia, bearing significant royal responsibilities. Her prominence emerges during the defense of Lestia's city of Merica against threats like the NEET God and the Phrase, fighting alongside Touya Mochizuki and his allies. This pivotal event leads to her eventual relocation to the Brunhild Dukedom.

Hildegard possesses long blonde hair often styled in a bun, clear blue eyes, and fair skin. Her typical formal attire includes a red and white dress with an elongated back, a white cape, thigh-high black stockings, and knee-high black boots. A silver tiara and an indigo bow adorn her hair, signifying royalty. In combat, she wears enchanted mithril armor decorated with gold. Originally bearing the Lestia royal family emblem, the armor's breastplate later displays the Brunhild Dukedom emblem after her engagement to Touya Mochizuki.

Her personality exhibits a chivalrous and dignified demeanor, often expressed through formal speech. She shares a deep passion for swordsmanship with Yae Kokonoe, earning them the joint nickname "sword art nuts" or "kenjutsu baka." While generally composed and stately, she becomes easily flustered or embarrassed in romantic scenarios involving Touya, revealing inexperience in matters of the heart.

As a royal knight titled "Knight Princess," Hildegard demonstrates exceptional swordsmanship. She masters specific Lestian Sacred Sword techniques: First Cutter (Wind Blade), Second Wardance (Fury Dance), Third Shear (Iron Slash), Fifth Swirl (Spiral), and Sixth Roaring Thunder (Thunderclap). Her combat prowess is significantly enhanced by a "Dependent Trait" called Improved Fighting Power, bestowed as a Retainer of Moroha Mochizuki. Her notable equipment includes the enchanted mithril armor, a Phrasium sword matching the Brunhild knight order design gifted by Touya, the heavy melee-focused Frame Gear Siegrune, and a Sacred Ring received as a wedding gift from the World God. This platinum gold ring acts as a conduit for Touya's divine power.

Hildegard transitions from Lestian royalty to becoming one of Touya Mochizuki's wives and the Third Queen of the Brunhild Dukedom. Their engagement occurred partly due to peer pressure from Touya's other fiancées. Following marriage, she resides permanently in Brunhild and becomes the mother of Freigard Mochizuki. Daily training sessions with Yae Kokonoe remain a consistent routine. She maintains a strained relationship with her grandfather, characterized as a dirty old man with inappropriate behavior towards women.

Trivia associates her with the Jupiter astronomical symbol, reflected on her attire. Within Touya's fiancées group, she frequently holds the third position: third swordswoman (after Yae and Lu), third princess (after Yumina and Lu), third blonde (after Yumina and Sue), and third in bust size (after Linze and Yae). Her birthday falls on April 3rd.
