Tohru

Tohru is a female dragon with the ability to transform into a human girl. After Kobayashi rescues her, she falls in love with her and decides to work for her as a maid.

As a Chaos Dragon, Tohru was raised to hate humans and was supposed to be a fierce and dangerous force of evil with nothing other than destruction in mind. However, this all changed when she met Kobayashi. She is now cheerful and kind to every human she meets, except for those who are real, or as it is in most cases, imaginary, threats to her love interest Kobayashi (such as Makoto Takiya). She is also quickly influenced by what she sees on television or the internet and shares a fiery relationship with her rival, Elma.

As Kobayashi's maid, Tohru is a hard worker and cares deeply for the household, tending to all aspects of daily life, although this will often lead to trouble, such as when Tohru tries to feed her tail to Kobayashi, or when she molests Kobayashi's dirty laundry. Still, Kobayashi always shows her appreciation for Tohru's efforts and does her best to guide Tohru in the ways of modern life and human culture on Earth. Tohru is very protective of Kanna and is essentially her mother figure and big sister combined. Having been accepted by Kobayashi even in her dragon form, Tohru quickly fell deeply in love with her. Even faced with Kobayashi's stoic character and often unrequited advances, Tohru never fails to make her unending love for Kobayashi known. Tohru's equally strong sexual attraction to Kobayashi often drives her to trickery, such as making a chocolate heart with a love potion secretly added, or finding different ways to attempt making Kobayashi eat her tail.
