In Sword Art Online, why does Suguha practice only one Kendo move? Suguha only does one kendo move whenever she's shown practicing in the show. Even in Ordinal Scale her video to Kirito was of that one move. Is there any reason for the lack of variation?
I assume you are refering to this move:

While I'm not an expert in kendo, the way kendo is usually depicted makes me think that that specific move is one of the basic excercises that kendokas need to practice as much as possible. It's one of the most common moves in kendo-centered series/episodes. Some examples:



Rurouni Kenshin: Meiji Kenkaku Romantan - Opening 1



Bamboo Blade - Episode 1



Katanagatari - Episode 9

A similar move in combat is the head strike (men), which Suguha used when she had a match with Kirito:
