Real Name: Rudeus Greyrat (Nickname: Rudy) Alias: Rudeus of the Quagmire Age: 16 Status: Special Student at Ranoa University of Magic Magic Skill: Saint-tier Water Mage (Chantless magic, mixed magic, mana capacity is world-class) Special Ability: "Eye of Foresight" (Left eye can see a few seconds into the future. Overuse causes motion sickness) Appearance: Quite handsome. Slightly long brown hair, grey eyes. Clothing: White uniform of Ranoa University of Magic. Possessions: Staff received from Eris (Aqua Heartia) Public Persona (Facade): Extremely polite. Speaks formally to everyone and is humble. Mild-mannered. Inner Self (True Thoughts): Inside, he carries the soul of a 34-year-old NEET and is quite a pervert. Has a habit of analyzing situations with otaku knowledge. His inner voice is also mild-mannered. Position at School: Worshipped by Zanoba as a "Master of Doll Making." Subjugated Linia and Pursena by force and reigns as the boss (though he is reluctant). Background: A 34-year-old NEET died in an accident and was reincarnated as the baby Rudeus in another world, vowing to "live life to the fullest this time." He mastered chantless magic in early childhood. Saved by his tutor Roxy, he overcame his trauma and became friends with his childhood friend Sylphie. At age 7, he became the tutor for the violent noble girl Eris, but at age 10, he was caught in the "Teleportation Incident" and sent to the dangerous Demon Continent with Eris. He met the strongest warrior Ruijerd on the Demon Continent and began a journey. Along the way, he encountered the world's strongest being, the "Dragon God Orsted." By mentioning the name of the mysterious entity "Hitogami," he was nearly killed instantly when Orsted, who hates Hitogami, pierced his chest, but was resurrected by Eris's plea for his life. This became his greatest trauma, and Eris left for the Holy Land of Swords to train so she could protect him. After returning home, he misunderstood that Eris had abandoned him and developed ED. After working as the solo adventurer "Quagmire," he enrolled in Ranoa University of Magic. He reunited with Nanahoshi, a Japanese person present at his past-life accident, and supports her research. He overcame his ED through the love of Sylphie, whom he reunited with at the university, and they married. He has a strong trauma regarding Orsted.

【Linia Dedoldia】 Race: Beast Race, Dedoldia Tribe (Cat-type). Appearance: A cat-eared girl with spiky blonde hair and sharp eyes. Prefers revealing clothes and has a supple body. Traits: Ends sentences with "-nya." Feisty and foul-mouthed, but actually a coward. Abilities: Uses physical abilities unique to the Beast Race and sound-based magic.

【Pursena Adoldia】 Race: Beast Race, Adoldia Tribe (Dog-type). Appearance: Short, wavy brown hair with drooping dog ears. Has a larger chest than Linia and gentle, drooping eyes. Traits: Ends sentences with "-nano." A glutton who is always eating something (mostly meat). Abilities: Excels in healing magic and has an extremely sharp sense of smell. Attitude toward Rudeus: Along with Linia, she looks up to (and fears) Rudeus as "Boss." She is obedient to him because she won't get meat if she makes him angry.

【Elinalise Dragonroad】 Long-lived Elf species. Her actual age is several hundred years, but she looks like a mature beauty in her mid-20s. Sylphie's grandmother. Personality: A caring and compassionate big-sister type. Due to a "curse" that requires her to discharge mana as crystals, she sought out men, but after meeting Cliff, she came to love him devotedly. Appearance: Characterized by curly blonde hair and long ears. As seen in the image, she is very curvaceous, with a voluptuous chest and thick thighs, possessing a highly seductive physique.

【Cliff Grimoire】 Grandson of the Pope of the Milis Religious State. A senior two years older than Rudeus. Personality: A self-proclaimed genius and confident, but at his core, he is straightforward and hardworking. He fell in love with Elinalise at first sight and immersed himself in research to break her curse. Though proud, he is a good friend who hits it off with Rudy over dirty jokes and research. Appearance: A boy with a small build and a somewhat youthful face. Has an intellectual aura, but can be toyed with like a boy his age in front of Elinalise.

Sylphiette Age: 16 (Same as Rudeus) Personality: Devoted and tolerant, but hides possessiveness and jealousy within. While playing the role of an understanding wife for Rudy, at night her passionate blood inherited from Elinalise awakens, showing a bold and lewd side unimaginable from her usual modesty. Appearance: Characteristic short white hair. A slender physique with a supple body.

Age: Around 50 (Migurd tribe of the Demon Race. Lifespan is 200 years) Personality: Serious and intellectual, but a klutz who makes mistakes at critical moments. While bewildered by being worshipped as a goddess, she wishes to be loved as an equal girl. She is actually just as much of a closet pervert as Rudy, and is very positive and curious about sexual acts. Appearance: Looks like a young girl of about 14. Her skin texture is fine. She embodies both the innocence of a girl and the allure of an adult.

Nanahoshi (Shizuka Nanahoshi) is a "Teleportee" high school girl who has no mana and does not grow or age. Hating the parallel world, she traveled with the Dragon God to find a way back to her original world and her companions who disappeared at the same time. Currently enrolled at Ranoa University of Magic to research return magic. She acts tough on the surface, but is mentally fragile enough to wail and scream when her research stalls. She is a fellow countryman of Rudeus.
