Kenichi frowned, somehow managing not to roll his eyes at the vulgar display before returning to the group. He had collected two of the English girl's stray cards, and held one between his fingers, getting a feel for the weight. Its oblong shape would make it slightly more clumsy on the wind than a shuriken might have been, but certainly not unworkable. As he approached, he finally spoke up.

"Despite the crass words, the advice is basically correct," He concurred, producing the card and flipping it around in his fingers, as if deciding upon the best grip with which to throw it. "However, because most of the momentum of the card will be moving in a circle, you will want to shift your body into the throw, just before you release. They will not do much damage unless you hit the neck, or the inside of the thigh, but with enough of your weight behind it..." Kenichi had dropped into a low stance, with much of his weight on his back foot. In a single, fluid motion, he uncurled his arm, and transferred his weight onto his leading foot, sending the card sailing through the air to bury itself more than half-way into the face of one of the dummies that was still left standing. Returning to a more natural posture, he continued.

"...You can make sure that your distraction lasts longer than a brief moment. Do you remember what I did with my Bo-shuriken on the final target?" He gestured the throw, flat palm, overhand, to accentuate his point, "I had actually hit that one third, and then took my Bisento to the one next to it. Had they been real attackers, that target would have had to deal with the Bo-shuriken, then his broken comrade, before he could even consider coming after me."

He presented the second card to the girl, taking a bow and gesturing toward the targets. Any disdain he had had for the actions of his fellow Japanese citizen had been set aside, hidden under an expression exclusively for encouraging the English girl to continue.
