Hisoka, the pleasure is mine. [He's both pleased and mildly bemused, given that it's yet another student with experience. He more meant this to be a beginner's class, but he's long since given up on keeping the more veteran players away from the dojo for the hour.]
You're absolutely welcome to join us. We have a few experienced swordsmen and women in our number already--can't hurt to add another, eh?
