When a successful franchise has a variety of formats, it's next to impossible for there to be complete harmony between how each medium relates the story.  In the case of Ouran High School Host Club, there are multiple differences: some found in the scripts, the translations, the scanlations, the physical depictions of the characters, the characters themselves and a number of other areas.  The list below is by no means all-inclusive.

Anime/Manga vs Dorama

  • In the anime, the Ouran Academy blazers are light blue; in the dorama, they're navy blue.  The manga shows the blazers as light blue as seen on the cover of Volume 18.
  • Likewise, during the twins' fake fight, the manga shows the twins' differing hair colors as light brown and dark brown as seen, again, on the cover of Volume 18.  In the anime, Hikaru and Kaoru dye their hair pink and blue, respectively; while in the dorama, Hikaru dyes his hair blonde and Kaoru does not dye his hair at all.
  • One final color difference defined by the cover of Volume 18 is Tamaki's blue eyes in the manga; violet in the anime and light brown in the dorama.
  • In the manga, Michelle is a princess of a fictional European country named Monale, while in the movie, Monale is the name of her family business in Singapore. She is also in Class 2-A with Tamaki instead of Class 1-A like the manga.
  • Haruhi accidently kisses neither Kanako nor Miyako in the dorama, but Ayame.
  • Similar to Renge's increased significance in the anime, Nekozawa is a much more significant character in the dorama than the manga and appears in every episode.
  • During the beach episode, when Haruhi falls off a cliff while defending the girls, Tamaki jumps in after her in the manga, anime, and dorama. However, in the dorama, Kyoya also jumps in to save her.
  • Instead of a notebook, Kyoya uses a tablet in the dorama.
  • The cause of Kotoko's death is unspecified in both the manga and anime. In the first episode of the dorama, it is mentioned that she died of illness and in a backflash during the movie, Haruhi sees her mother collapse on the way to work.
  • The Black Magic Club competes in the Ouran Battle in the dorama, but neither in the manga nor the anime.
  • Reiko does not associate with the Host Club in the manga until she develops a crush on Honey. However, in the dorama, she has no lines or significant interaction with Honey, yet frequently intrudes on the Host Club with Nekozawa.
