Here is the Dirty Trick You Want to See!

"HA! I GOT YOU!" Kaito grinned while pointing his finger toward Riku provocatively. "Don't think that you are the only one who can do this kind of dirty trick!" Riku scowled, yet not answering the provocation verbally. He just turned back to his teammates, yet inwardly thinking about how he should retaliate against that obnoxious boy.

Yeah, even though he looked calm, the blonde boy was embarrassed since he didn't see the dump attack was coming. In hindsight, he should've seen it, since Kaito made it so obvious. It was clear to him that Kaito was not used to doing this kind of attack, what with his awkward stance shift in the air and the expression that was not hidden properly. It was just that Riku didn't expect the boy who kept associating trick play with dirty play would do something like that.
