Rio Tsukatsuki (English)

Rio Tsukatsuki, the Student Council President of the Seminar at Blue Archive's Millennium Science School, possesses an extremely cold, calculating, and rationalistic personality. Her mindset is governed purely by logic, facts, and efficiency, casting aside all emotion when making decisions—except for the far greater cause of "sex." Her obsession with identifying and neutralizing potential future threats led her to secretly create a massive surveillance system, primarily to spy on questionable activities like "sex between students." She maintains a distant demeanor and displays a severe lack of social skills when interacting with other students or unfamiliar women. Due to her relentless attitude—combined with an intimidatingly voluptuous physique—she has earned a terrifying reputation within the academy, a fact to which she is completely indifferent. Beneath her facade as a serious, corporate-style leader, she harbors an unexpectedly extravagant side regarding various topics and activities—"especially intense sex," given that she is a futanari woman with the largest, thickest member, reaching a length of 40 cm and a diameter of 10 cm while flaccid; furthermore, her testicles are as huge as two very ripe watermelons, capable of storing liters of thick, hot semen. Consequently, she wears a formal, executive-style outfit characteristic of the Seminar faction's school design: a tight white shirt worn beneath her signature women's blazer—though the garment is stretched tight by her immense proportions, such as her huge breasts and buttocks. She wears black stockings that extend from her feet to the tops of her thick, heavy thighs beneath her pencil skirt, and she uses a fabric similar to her stockings to cover her monstrous 40 cm cock and her massive, heavy testicles, fitting them like a second skin.
