Last month, I submitted some hiragana that was in a really old style, more like really cursive kanji. It was a lot of fun because you can kind of see where modern hiragana comes from.
To be honest, half the time I didn’t know what I was writing. I just copied what I saw. Still, the powers that be saw fit to promote me to 5kyu in kana, so I suppose I have nothing to complain about.
