Kenshi was trying his best at ignoring the challenge to his authority, he wanted to go hardcore SDC on the usurper  but get would probably be getting a mouthful by Sakura afterwards which would also entail him having to fulfil some epic quest of getting pudding for her or something like that.

He jumped off the stage and glared daggers into the girl's eyes as he walked off. As his strides took him towards the dojo, he called over a member of the SDC and instructed him, "Remind me to keep an eye on her. What's her name anyways?"
"Keiko Murata." the boy said before adding "sir" after he got a look from his superior.
"Thank you. Make sure she gets her ass into detention. Now, I'll be taking my leave. Don't disturb me unless you enjoy a bokkun being sent at your face."

Kenshi stomped off into the empty dojo. Pushing open the door into a side room , he put on training clothing as well as dragging out a training dummies made of. As he stripped off his shirt, he looked at a small heart shaped locket around his neck. Opening up revealed the smiling face of both him and Touka before he had lost his eye and she forgotten about him.

His metal joint squeaked as he sank to one knee and could feel a tear roll its way down his face. Brushing away his emotions, he stood up and slammed open the door and begain to work on his sword skills and strength. He had already failed Touka because of his weakness, he wasn't about to loose the school to it too.
