Vol. 4 - Chapter 20

Sinneah dodged out of the way of Yumi's naginata, and then, with a surprising speed, she lifted a foot off the ground and tried to kick Yumi's head from the side. Yumi saw it coming though and ducked, before sweeping the floor with her blade. Sinneah jumped back, avoiding the attack before putting one fist in front of her. 

The entire time, she was keeping one hand tucked away. Yumi noticed this and wondered if she was particularly strong with it for some reason, and was looking for an opening. Regardless, she ran up again and this time, went for a vertical slash. 

Sinneah sidestepped, and then went for a punch with her left hand that Yumi dodged easily. 

Still, the large woman moved with a quickness that did catch Yumi off-guard. 

I wonder what her Dex is...  Yumi thought.  I wouldn't have expected someone like this to have a high stat in that category, but she is surprisingly agile.
