Cute ciel appears way more in the manga, also, the fucking 2008 anime adaptation is shounen garbage filler. They butchered the storyline so badly.
Backstory on why the plot & characters were butchered in the anime adaptation:
In 2008, the manga had only been out for 2 years. There was not a lot of source material to adapt from, so they had to create original characters and then create their own non-canonical ending for Season 1.
The newer anime adaptations from 2014 & 2017 is amazing though, so be sure to try them out whenever.
List of the newer anime adaptations in Chronological order (don't watch until you at least reach the prologue of the circus arc in the manga).https://anilist.co/anime/20606/Black-Butler-Book-of-Circus/https://anilist.co/anime/20670/Black-Butler-Book-of-Murder/https://anilist.co/anime/21425/Black-Butler-Book-of-the-Atlantic/
The newer ones hasn't even adapted the school arc which is the epitome of ???? Ciel, so, please, read the manga... even if it's too shounen at the beginning. The art gets so much better.https://i.imgur.com/3msASlu.png
