Magical Witches

Magical Witches (マジカルウィッチーズ Majikaru Wicchzu) is a series of magic book-shaped virtual pets released by Bandai in 1998. They are collectively referred to as the "Four Elements Communication Books". Watanabe Kenji was involved in the character design and as a consequence, some elements from the series were incorporated into the Digimon franchise, in particular Witchelny, the main setting of Magical Witches, which was adapted into being an alternate Digital World and the magic used by its inhabitants as being "advanced programming languages".

Clans
In the Witchelny of Magical Witches, there are four clans of witches that each represent one of the used in alchemy. Witchmon's Special Moves are a reference to the these clans.
