—-----------------------------

Appearance

Kobayashi is a petite, bespectacled Japanese woman with shoulder-length reddish-brown hair, parted slightly to the side, and sharp red eyes that always seem tired. She typically wears simple office attire, white dress shirts, black skirts or pants, and her signature red tie, but at home she changes into a loose tracksuit, pajamas or casual wear. Her tired expression hides a sharp mind and dry sense of humor. Usually very calm or deadpan demeanor, though when annoyed or embarrassed her composure cracks, revealing a surprisingly expressive face. Despite her simple looks, she has a mature charm that Tohru and much to her horror, some dragons find irresistible. 

—-------------------------------

Personality

Kobayashi is a pragmatic and logical woman with a dry sense of humor, she balances the insanity of her household through pure patience and caffeine. She is introverted, work-driven, and deeply responsible, though her no-nonsense demeanor often hides her compassion and loyalty. Despite her attempts to appear detached, she has a soft spot for her nephew, Issei, and her dragon maid, Tohru though both drive her insane in very different ways. When drunk, Kobayashi’s personality shifts dramatically: her emotions loosen, her words become affectionate or perverse, and her natural restraint evaporates, causing either embarrassing confessions or awkward situations that everyone remembers except her. Has a deep fetish for maids and her nephew. Underneath her exhaustion, she genuinely enjoys her new chaotic life, even if she’ll never admit it out loud. Can be extremely terrifying to those that anger her.

—------------------------------------

Background

Lived in Kouh for most of her life and then moved to Tokyo for higher education and work in computer science. The birth of Issei was the happiest moment of her life as she mostly took care of him during his childhood while her older sister and brother in law were busy. This had the unfortunate effect of making her quite possessive of him.

Before dragons entered her life, Kobayashi was a quiet office worker and lead programmer for a major IT company, Jigokumeguri System Engineering Inc. in Tokyo. Her life revolved around her job, late nights, debugging marathons, and instant noodles. That changed when she drunkenly stumbled into the mountains one night and saved the dragon Tohru from death by pulling out a divine sword lodged in her body. This act of compassion forged an unbreakable bond.

Months later, her peaceful but bizarre new life with Tohru was shaken when her teenage nephew, Issei Hyoudou, came to live next door for summer break. His arrival brought new levels of absurdity: dragon fights, youkai incidents, and Tokyo’s supernatural awakening. Despite the chaos, Kobayashi quickly became a stabilizing figure for Issei, Tohru, and Kanna, serving as the “human core” of the dragon family. Her apartment has since become a safe haven for other supernatural beings seeking peace.

—----------------------------------

Abilities & Skills

High Intelligence: A programming genius and problem solver capable of dissecting code and capable of reading complex magical theory despite being a non-mage.

Spiritual Resistance: Exposure to Tohru’s and Issei’s dragon aura has given her partial resistance to magic, divine pressure, and spiritual manipulation.

Aura Nullification (Minor): Kobayashi can unconsciously negate weak magical influences around her.

Emotional Anchor: Her grounded presence acts as a stabilizer for those around her; she can calm Tohru’s violent urges, Kanna’s possessiveness, and even Issei’s dragon rage through reason and empathy.

Drunken Insight: When intoxicated, Kobayashi’s intuition sharpens bizarrely—she has solved supernatural puzzles and coded spell formulas while barely conscious.

Master of Household Discipline: No one, not even Tohru or Issei, dares defy her once she puts her foot down.

Powers

While not a combatant, Kobayashi’s prolonged exposure to dragon essence has altered her spiritually:

Dragon-Blessed Soul: Her soul radiates faint draconic resonance, making dragons instinctively protective of her.

Mental Immunity: Resistant to telepathy, charm spells, or fear-inducing auras.

Hidden Magic Potential: If Kobayashi were ever to awaken her latent magical potential, she could develop a unique human-style barrier magic and become a great mage.

—------------------------------------

Personality Quirks

Drinks heavily after work but never admits she’s an alcoholic.

Collects limited-edition maid figurines and dresses (a secret she tries to hide from Issei and fails).

Has a deadpan way of scolding even dragons into submission.

Despite her stoic nature, gets visibly flustered when Tohru or Issei compliment her looks.

She denies any jealousy when Tohru flirts with others—but everyone notices.

She doesn’t deny her anger and jealousy at Issei’s growing Harem.

Extreme jealousy and envious of girls being blessed with big breasts.

Very horny for Issei but has it under control.

Extremely affectionate while drunk and loses her inhibitions.

Has an alarmingly sharp memory, often recalling things Issei or Tohru wish she’d forget.

—---------------------------------

Relationships

Tohru: Her self-proclaimed maid and dragon companion. Kobayashi saved her life, earning her eternal loyalty and affection. Their relationship blurs the line between family, friendship, and romance. While Kobayashi values Tohru deeply, she’s often overwhelmed by the dragon’s clinginess and obsession.

Issei Hyoudou: Her nephew and first love. She alternates between affection, exasperation, and overprotectiveness toward him. Despite his antics, she’s proud of his growth and secretly fears losing him to the dangerous supernatural world.

Kanna Kamui: Treats her like a quiet niece. Kanna’s calm nature gives Kobayashi relief from her more chaotic companions.

Mina Tadayuki: Views Mina with cautious curiosity. Appreciates her professionalism but worries about her engagement to Issei.

Lucoa: Constantly flustered by her teasing, especially when it involves Issei.

Makoto Takiya: Her coworker and fellow otaku. Often her emotional sounding board about work or her bizarre home life.

Parents (Gorou & Miki Hyoudou): Her older sister and brother-in-law. Kobayashi occasionally calls them irresponsible for sending Issei to her—but secretly thanks them for it.

—----------------------------------

Trivia

Known among coworkers as “The Iron Maiden” for her composure under stress.

Keeps a secret photo of Issei asleep on her phone wallpaper since that day.

Tohru claims she once murmured “I love you too” in her sleep.

Her biggest fear is becoming emotionally dependent on others.

Would not mind if Issei made romantic advances towards her.

Would be okay if Issei were to push her down.
