Mitsue, a human succu-girl in her fifties, possesses sweeping lilac hair and a serene presence marked by perpetually closed eyes. Her soft, mature figure stands at 155 cm, often draped in an elegant purple gown adorned with a pearl necklace and bold crimson lipstick. Known for her tranquil warmth, she mentors both younger and elder succu-girls, including the elf Elma, whose youthful guise belies Mitsue’s superior mana refinement.

For thirty years, the elf Zel has frequented Mitsue, drawn to her exceptionally potent mana reserves, which he deems fresher than the stagnant energy of long-lived races. This preference ignites a rivalry in the series’ opening arc: Zel’s fervent admiration for Mitsue clashes with Stunk’s partiality toward Elma, culminating in a public review contest to settle their dispute. Patrons’ scores vary widely—Zel awards her a 9, lauding her vigor and skill; Stunk scorns her age and form with a 2. The beastman Brooz rates her a 7, favoring her curves over orc companions, while the halfling Kanchal grants a 3, noting her uncommon allure but dismissing human elders as unappealing.

Mitsue’s enduring career bridges generational divides among succu-girls, emphasizing how species contrast in valuing age and beauty. Her steady guidance and resilience in the profession reflect her role as both caretaker and symbol of lasting expertise, anchoring discussions on desire and tradition within her world.
