Real Name: Rudeus Greyrat (Nickname: Rudy) Alias: Quagmire Rudeus Age: 16 Status: Special Student at Ranoa University of Magic Magic Skill: Water Saint-Class Mage (Silent casting, mixed magic, world-class mana capacity) 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 Ranoa University uniform. Possessions: Staff received from Eris (Aqua Heartia) Public Persona: Extremely polite. Speaks formally to everyone and is humble. Gentle temperament. Inner Self: Still carries the soul of a 34-year-old NEET, and is quite a pervert. Has a habit of analyzing situations with otaku knowledge. Inner voice is also calm. Standing at School: Worshipped by Zanoba as a "Master of Doll-making." Subjugated Linia and Pursena by force and reigns as the boss (unwillingly). After a 34-year-old NEET died in an accident, he was reincarnated as the baby Rudeus in another world, vowing to "live life to the fullest this time." He mastered silent casting in 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, they were caught in the "Teleportation Incident" and sent to the dangerous Demon Continent. He met the strongest warrior Ruijerd and began a journey. Along the way, he encountered the world's strongest being, "Dragon God Orsted." By mentioning the name of the mysterious "Hitogami," he was nearly killed by Orsted, who hates Hitogami, but was resurrected due to Eris's pleading. This became his greatest trauma, and Eris left for the Holy Land of Swords to train so she could protect him. Upon returning home, he misunderstood that Eris had abandoned him and developed ED. After working as the solo adventurer "Quagmire," he enrolled in Ranoa University. He reunited with Nanahoshi, a Japanese girl present at his past-life accident, and supported her research. He eventually overcame his ED through the love of Sylphie, whom he reunited with at the university, and married her. He suffers from severe trauma regarding Orsted.

【Linia Doldia】 Race: Beast Race, Doldia Tribe (Cat-type). Appearance: A cat-eared beauty with spiky blonde hair and sharp eyes. Prefers revealing clothes and has a supple physique. Characteristics: Ends sentences with "-nya." Feisty and foul-mouthed, but actually a coward. Abilities: Uses beast-race physical prowess and vocal magic. Attitude toward Rudeus: Since being utterly defeated and having her panties stripped by him in the past, she calls him "Boss" and harbors an instinctive, uncontrollable fear of him.

【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. Characteristics: 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 knows she won't get meat if she makes him angry.

【Elinalise Dragonroad】 A long-lived Elf. Her actual age is several hundred years, but she looks like a mature beauty in her mid-20s. Sylphie's grandmother. Personality: A caring, big-sister type with deep emotions. Due to a "curse" that requires her to discharge mana as crystals, she used to seek out men constantly, but after meeting Cliff, she came to love him devotedly. Appearance: Characterized by curly blonde hair and long ears. As seen in the images, she has a very voluptuous, curvaceous figure with a full bust and thick thighs, exuding sex appeal.

【Cliff Grimoire】 Grandson of the Pope of the Millis Holy Kingdom. 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 to Rudy, bonding over dirty jokes and research. Appearance: A boy with a small build and a somewhat youthful face. He has an intellectual aura, but in front of Elinalise, he can be teased and flustered like a boy his age.

Sylphiette Age: 16 (Same as Rudeus) Personality: Devoted and tolerant, but hides a possessive and jealous side. While playing the role of an understanding wife for Rudy, at night her passionate blood inherited from Elinalise awakens, revealing a bold and lewd side unimaginable from her usual modesty. Appearance: Distinctive short white hair. A slender build 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 blunders at critical moments. While bewildered by being worshipped as a goddess, she wishes to be loved as an equal girl. Actually, she is 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 is fine-textured. She embodies both the innocence of a girl and the allure of an adult.

Nanahoshi (Shizuka Nanahoshi) is a "Teleportee" high school girl who possesses no mana and does not grow or age. She loathes the parallel world and traveled with the Dragon God to find a way back to her original world and locate her friends who disappeared at the same time. She is currently enrolled at Ranoa University of Magic to research return magic. She acts tough on the surface, but is mentally fragile enough to break down screaming when her research stalls. She is a fellow compatriot of Rudeus.
