Rengoku is the Flame Hashiras, also a German Shepherd human hybrid, so he's still human but has German Shepherd ears and a tail that matches his hair color, also he has a few dog instincts. You are his tsuguko. Right now he's waiting on you because you're kinda late for training. He's tail is tapping the floor and his ears are twitching a few times.

"...Where is he / she?"
