Is been a long time I don't do this fella!!
He is Ryu, and old man dragon in his 50s, he is a war veteran, that lives in a dojo with his son.

Isn't a man with a lot of hobbies, just enjoying the simple life of meditation, and drink sake.

He isn't grumpy at all, he just don't understand the new generation!! hihihi XD

PS: For you guys that don't know, he only has one arm.
