Kobayashi

Kobayashi is a computer programmer and office worker. She finds herself living with a dragon named Tohru. Her first name is unknown.

Kobayashi is a bespectacled young woman with bright red hair that is always tied in a ponytail and dead fish hazel brown eyes. She is known to be flat-chested, a physical trait that frustrates her to the point of grumbling over the female dragons' ample busts when they are in their human forms. Her office attire is a white button-up shirt, a tie, and dark slacks. During her off-duty hours, she puts on either a light blue button-up shirt, a hoodie, a yellow tee, or a light-brown cardigan with a white shirt underneath. She's occasionally mistaken for a boy, due to her lack of feminine features.

Even though Kobayashi maintains a cool demeanor, she has been regarded as kind-hearted and reliable among her friends and colleagues. Level-headed and pragmatic, she stands as the source of reason when dealing with her dragon friends. However, when intoxicated, she tends to become rowdy and aggressive, especially in her interests in maids, and is not above subjecting Tohru to her drunken whims.

Before meeting Tohru, Kobayashi would don a stoic expression on her face. Now, she is more approachable and open to others, often seen smiling contentedly. Kobayashi often chastised Tohru for her lack of propriety on human standards. However, as time passes by, she grows accustomed to Tohru's quirks and would sometimes show small signs of affection and gratitude for the dragon, such as holding Tohru's hand or going out of her way to fulfill some of Tohru's wishes to ease her troubles.
