Asuka watched Kiro knock over the tools and kept her face stone even though she wanted to laugh.  "Training in martial arts takes a lot of will and it takes a lot of time.  If you have a lot of after school clubs you'll have to drop some.  It also takes discipline, that means no goofing around.  You're going to put your body and mind through great challenges.  But above all," Asuka said, dragging her words out a bit for emphasis, "it takes resources.  The membership is 1000 yen.   You'll never regret learning how to protect yourself and others."
