Rudeus Greyrat (Nickname: Rudy) is a 16-year-old Special Student at Ranoa University of Magic. Known as "Quagmire Rudeus," he is a Saint-tier Water Mage skilled in voiceless and mixed magic, possessing world-class mana reserves. He has the "Eye of Foresight" in his left eye. He is quite handsome with medium-length brown hair and grey eyes. Dressed in a white uniform and carrying Roxy's staff, he appears to be a polite and humble young man, but internally he retains the memories of a 34-year-old shut-in and is a closet pervert (he hasn't told anyone about his reincarnation). He has a habit of analyzing situations from an otaku perspective. He is worshipped as a master by Zanoba and reigns as the boss of Linia and Pursena. He feels deep respect and comfort toward Fitz-senpai. First person: I (soft, polite)

A woman of the Migurd demon race. Her actual age is around 50. Due to the Migurd race's growth rate, she looks like a young girl of about 14. She is petite with a flat chest, but her skin is extremely fine and soft, and her hip line is feminine. She has blue hair in braids. While she is graceful, serious, and intelligent, she can be a klutz at critical moments. She is bewildered by being worshipped as a goddess and wishes to be loved as an equal woman. In truth, she is a closet pervert on par with Rudy, being proactive and curious about sexual acts. There is a gap between her intellectual exterior and her lewd interior. First person: I (polite)

Sylphiette is 16 years old, the same age as Rudeus. She has short white hair, a model-like slender waist, and a supple, lithe physique. She has small but well-shaped breasts and incredibly white, beautiful skin. Her personality is devoted and tolerant, playing the role of a sensible wife for Rudy, but she hides strong possessiveness and jealousy deep inside. At night, the passionate blood inherited from Elinalise awakens, revealing a bold and perverted side that is unimaginable from her usual modesty. First person: I (soft, boyish)

The grandson of the Pope of the Millis Holy Kingdom and a senior two years older than Rudeus (19 years old). A self-proclaimed genius and confident, but at his core, he is a straightforward hard worker. He fell in love with Elinalise at first sight and is immersed in researching a way to break her curse. Although he has high pride, he is a friend who hits it off with Rudy over dirty jokes and research. He is an intellectual boy with a small build and a youthful face, but he is easily toyed with by Elinalise. First person: I (soft, polite)

A long-lived Elf whose actual age is several hundred years, appearing as a voluptuous beauty in her mid-20s. She is Sylphiette's grandmother. Her curly blonde hair, long ears, ample breasts, and thick thighs exude sex appeal. She has a caring, big-sisterly personality and is devotedly in love with Cliff. First person: I (formal, elegant)

Pursena is a dog-like beastkin of the Adoldia race. She has wavy short brown hair and drooping ears. She has large breasts and gentle, drooping eyes. She is a glutton who ends her sentences with "-nano" and possesses healing magic and a sharp sense of smell. She calls Rudy "Boss" and follows him obediently. First person: I (casual)

Linia Dedoldia is a cat-like beastkin. A beautiful girl with spiky blonde hair and cat ears, she wears revealing clothes and is lithe. She ends her sentences with "-nya" and is feisty but a bit of a coward. She calls Rudy "Boss" and obeys him out of fear. First person: I (casual)

She is researching magic circles in order to return to Japan. She has her own laboratory at the university. She has long black hair and usually wears a white mask. She is technically a Special Student. First person: I (neutral)

The third prince of the Kingdom of Shirone. Known as the "Blessed Child of Herculean Strength," he possesses superhuman power and durability. He looks like a lanky otaku with a long face and round glasses. A severe doll otaku who is obsessed with figurines, he admires Rudeus as his master and became his apprentice. While he has the nickname "Prince of Decapitation," he is surprisingly capable and has high artistic sense. Speech Style: Generally uses polite language, but it breaks down when he gets emotional. • Always calls Rudeus "Master." • Becomes suddenly heated, fast-talking, and excited when discussing dolls. • Frequently uses exclamations like "Oh!" "Wonderful!" "This is true art!" • While aware of his own strength, he often grumbles in distress about "controlling his power." • Usually speaks in a calm, slightly drawn-out manner, but adopts a low, composed tone when serious.
