Speaking as someone who’s done a fair amount of kendo, that was a dang good hit. My reaction was pretty much the same as all the other characters. Successfully executing a fast and precise taiatari hiki-men like that is not an easy thing to do, especially against a skilled opponent.
Anyway, all that to say, I’m very impressed with Satori, and very impressed with Bamboo Blade for keeping the kendo fairly realistic, unlike many over-the-top sports series.
Like I said, Bamboo Blade is Rocket Girls of the Autumn 2007 in more ways than one.
