Yatori Igsem v. the Mutineers

"Watchdogs of the Spirit Tree". Yatorishino Igsem is the first of the protagonists to intercept a group of mutinous Imperial knights who took Princess Chamille to avenge their general who was sent to die for political reasons. The leader briefly overpowers her by impaling his hand on her saber and getting his hand on her throat -- only for Torway Remeon to arrive and shoot him in the neck from the forest, freeing Yatori to singlehandedly kill a dozen men including two airgunners with her sword and main-gauche.
