Vegan Eldriel, a high elf ambassador representing her tribe, possesses long blonde hair typically in twin tails, blue eyes, pointed ears, and pale skin. She wears a green dress with white seams and large sleeves, a brown belt, beaded headband, choker, and white sandals. Her petite frame and notably flat chest fuel insecurity and frustration when Peter Grill shows no sexual response.

Arrogant, self-centered, and condescending toward non-elves, Vegan embodies elven superiority. She prizes her attractiveness and reacts angrily to mockery of her physique, especially her breast size. Ruthlessly persistent, she manipulates others using forbidden magic or blackmail to achieve her goals. Beneath her haughtiness lies an underlying kindness, with motivations rooted in protecting her family.

Her mission targets Peter Grill’s genetic material to sire a powerful half-elf child, restoring her tribe’s honor after their Grand Fighting Tournament defeat. After failing to rape him in his sleep due to his unresponsiveness, she curses him with "Eternal Erection," threatening permanent genital damage if he refuses compliance. She confronts him at a hot spring, revealing sex with her is the only cure, which he accepts under duress, initiating recurring encounters.

She fiercely competes with Peter’s harem members like Lisa and Mimi. Following a physical defeat due to elven fragility, she devises a magical arousal-measuring device, dismayed by its low readings for her. She joins a harem treaty systematizing access to Peter, enforcing compliance through threats of exposure.

Her background reveals the Eldriel family, once noble elves, faced bankruptcy after Vegan damaged their village during a quarrel with her younger sister Fruitalia. This strained their relationship, though tensions eased slightly during later collaborations. Vegan’s pursuit of Peter’s seed also aims to spare Fruitalia the humiliation of acquiring "inferior" human genetics, reflecting hidden familial responsibility.
