FYI later Samurai not only had armies that used guns but some of their most elite ranks had armor just as heavy as European knights. So Samurai would honestly be almost tied to knights at their peak unless you define knights as anyone with the rank.
Unrelated but what do you think of the chariot card for the Shiny Rod? https://little-witch-academia.fandom.com/wiki/Chariot_cards
The Shiny Rod one in English says Chariot created the sun and the moon but that doesn't make sense with lore afaik so i considered it just being hard to translate, although the second sentence provides speed consistency
