Hey guys, so there's three Hiragana today because Kaneki has a really good name that uses three of the Hiragana. So, there's か or "ka" pronounced "kah" like in Kai. き or "ki" pronounced "key", this one doesn't need an example word because it's honestly just key. And then け or "ke" pronounced "keh" as in Ken. For any EXO fans, Kai's name is spelled かい in Hiragana ^^ Underneath is stroke order.
In Japanese when you add, what's called, a tenten it changes the sound. Adding the tenten to Ka, Ki, and Ke changes them to Ga, Gi, and Ge. Nothing to difficult the tenten is the two extra lines drawn in the top right corner.
がんばって～！ Good luck~!
