[... !!!

This mysterious stranger has a point! He has been incredibly rude in not introducing himself before seeking out fellow members of this new clan he's found himself in.

So. He bows as deeply as he can, given that he's still technically kneeling on the ground, before rising up again.]

My deepest apologies! I should have introduced myself long before you felt the need to prompt me on my poor manners! [He smacks his hand into his chest with ... an audible sound, but he doesn't seem to have felt it.]

I am Sanada Genjirou Yukimura. It is a honour to meet you.
