"Marui-san, if he wants it, maybe you should show him what you can really do!"

Yanagi cuffed Akaya on the back of the neck before he could say anything else.

"Quit it," he said, too calm to be snappish, but cutting Akaya off instead of saying something more explanatory like You're distracting me or I set this up and I want to see it through.

Too busy collecting data (swing speed, foot speed, attitude, etc), Yanagi missed the baleful look Akaya shot him.
