Took kenjutsu back in the day, though we unfortunately merged with a kendo school and I eventually left. The kendo class had too many rules like "You can't use diagonal cuts as a white belt."
....I am perfectly capable of making a diagonal strike. It's not a feat that I have to unlock next level.
Managed to take ninjutsu for a few months before I left the country for two years, and sadly my instructor moved away while I was gone.
On the bright side, I'm going to try German longsword tomorrow with the local ARMA group.
