Katsuhiko reached the mid point of the stair when he saw her. Her strange choice of clothing aside he couldn't help but be drawn to her. But that thought quickly left his mind as his eyes saw the blade in her hand. "Brendan!" He yelled instantly worried for his friends safety. Leaping down the stairs he took no note that his towel flew off and he was flying naked. Only the thought that his friend may be hurt entered his mind. His knees drawn towards his chest and his hands forward to defend against an attack Kat moved to secure his friends safety even if that meant he'd have to hit a girl.
