Fafnir

Fafnir  (ファフニール Fafunīru) or  Takeshi Ooyama  (大山 猛  Ōyama Takeshi) is a male dragon and a supporting character.

Appearance
In his Human form, he appears as a long, straight haired man in butler attire. He has red eyes which can change color and size depending on his rage. He has a calm, collected demeanor which reflects his slightly gloomy face.

When he is in dragon form he appears as a towering dark dragon with 3-4 pairs of pure red eyes.

Personality
In the beginning of the series, Fafnir abhorred humans for everything they were. As the series goes by his heart warms up to a human with similar interests and takes on a sensei-patawon style friendship and gets (Takiya Makoto) as a friend. His hatred for humans turns into more of a indifference to them, and more of a pain to get to know them rather than just kill/ignore them.

Due to this, he became extremely addicted to video games and other Otaku interests since his life style of a cursed dragon can easily accommodate it. He is hardworking and diligent for his passions as seen with his multiple all-nighters to play games.

Powers
Curses- He has the ability to curse and even wrote a book filled with real curses and tried to sell it at comicon, sadly not a single copy was sold so its true worth never showed.

Trivia
‌• Tohru calls him Mr. Fafnir
