Tohru

Tohru (トール Tooru) is one of the main characters in the series Kobayashi-san Chi no Maid Dragon.

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.

Appearance
In her human form, Tohru has long blonde hair and red-orange eyes. She magically transforms her scales into a maid outfit, copying the uniform from a maid cosplay cafe (Maid Cafe Cozy) after flying to Kobayashi's apartment the first time.

When in the private comfort of Kobayashi's apartment, Tohru wears her tail out, and on occasion, her wings. Outside, she hides both her tail and wings but retains her horns. Anyone who notices usually chalk it up to a form of cosplay.

Tohru's dragon form appears as a big green European dragon with black wings and a light green underbelly. The height of her dragon form towers over Kobayashi's old apartment that's four stories high.

Background
Tohru was raised to believe that humans were evil, inferior and foolish beings, which explains her initial distaste of the human race and her alignment with the Chaos Faction. She was heavily injured by a god leading a human army in her last battle, forcing her to retreat to the modern world to hide where she meets Kobayashi, who rescues her from the verge of death. On that same day, she falls in love with Kobayashi and takes her up on her offer to live with her as her maid.

Powers and Abilities
Tohru claims that she is one of the more powerful dragons capable of bringing about the Armageddon. She appears to be capable of opening portals to other worlds or dimensions with ease, a rare ability seeing as both Kanna and Elma, despite the latter being equal to Tohru in terms of power, do not possess this particular skill. Lucoa, a former deity, has this ability as well, after implying that she frequently travels between the two worlds to check up on Tohru. //ref

Kobayashi
Tohru is deeply in love with Kobayashi. She does her best to serve Kobayashi as her maid everyday and hopes that someday they'll share feelings.

Kanna Kamui
Tohru and Kanna get along pretty well since they have known each other for a long time. Tohru even teaches Kanna about the human world.

Takiya Makoto
Tohru dislikes Takiya to a point, initially suspecting him of being attracted to Kobayashi (though she later learns that this was not the case). She puts up with him for Kobayashi's sake, seeing as he means well as a friend and colleague.

Lucoa
Lucoa is one of Tohru's old friends and as such, cares about her. Before taking residence in the modern world, she goes out of her way to travel between worlds to check up on Tohru, often dropping by Kobayashi's apartment to visit.
