Description
Mercelída Ygvar is the reigning monarch of the Ygvar Kingdom in the anime Astarotte no Omocha!. As a succubus queen, she is the mother of both Princess Astarotte Ygvar and Asuha Tohara, a human girl from Earth. Standing at 175 centimeters tall, she has a mature and voluptuous figure, with blonde hair and green eyes, and possesses the defining physical traits of her race including wings and a tail.

Her personality is notably hedonistic, and she is widely known throughout the realm for her lascivious nature, maintaining a personal harem that numbers over three thousand individuals. Despite this frivolous public persona, she carries a deep sense of melancholy and tragedy from her past. She was once very close to her two elder sisters, but their bond was destroyed when both were manipulated by their retainers into fighting each other for the throne, ultimately poisoning one another to death. This traumatic event left Mercelída with a profound sorrow regarding the burdens of royalty, and it directly shapes her motivations as a mother. She is deeply committed to preventing her own daughters, Astarotte and Asuha, from ever facing a similar fate of fighting over the crown. This is believed to be the primary reason she sent Asuha to live in the human world with her father, secretly keeping her existence hidden and claiming the child had died, in order to remove any future political conflict between the two sisters.

Mercelída genuinely loves and cares for both of her daughters, but she struggles to express her emotions or relate to them in a normal family setting. This difficulty in communication often creates distance, particularly with Astarotte. Her relationship with the human man Naoya Tohara is also foundational to the story. Eleven years prior to the main events, she had traveled through the World Tree to the human realm on a whim. Severely weakened by the journey and needing to replenish her magical energy, she sought a male partner. Her initial intention was not to involve the young Naoya, who was only eleven years old, but after an accident prevented his parents from returning home, she had no other choice. She used magic to make him forget the encounter, believing it was a dream. She neglected to use a contraceptive spell, however, and later discovered she was pregnant with his child, Asuha, an outcome she privately found pleasing as she secretly refers to Naoya as her darling.

As a pure-blooded succubus, Mercelída displays the unique biological development of her kind. She sprouted her wings at the age of ten years and two months, which is akin to a human girl's first menstruation, and within the following ten months, she physically matured to the stature of a sixteen-year-old. As a queen, she often finds the administrative and diplomatic duties of ruling a small, conflict-ridden kingdom to be tedious and stressful. Consequently, she is known to skip official ceremonies and governmental affairs to go off on her own to relax, leaving such responsibilities to her ministers.
