During Touya's fight with Kurama he uses his ice abilities to form a sword around his arm. As he prepares to deliver the final blow, he remarks "It seems that I've gotten to know you quite well in such a short fight, and I rather like you. Let's not have this slaying ruing our friendship." Then in this cel, he brings his sword forward and prepares to strike.

I love the detail on the ice in this! What a pain it must have been to animate though.
