Who's Going To Win This Competition!?

Ever since elementary school, Kurokawa has always chased after the back of kendo prodigy Kazuha Momoi. He had always admired the other boy's style of kendo, but upon entering the same high school, a rivalry was born. Not only was Kazuha extremely arrogant in his eyes, but Kurokawa could never seem to defeat him. Having now entered the same college, Kurokawa assumes that their rivalry will continue. However, he is disappointed to hear that Kazuha has quit kendo. After relentlessly pestering Kazuha to join their college's kendo team—and repeated rejections from Kazuha—Kurokawa finally challenges Kazuha to an official match. If Kurokawa wins, Kazuha must join the team, but if he loses, Kurokawa will do anything the other boy wants him to. Suffering a quick defeat at his rival's hands, Kurokawa is forced to accept Kazuha's request. However, the request Kazuha makes is something Kurokawa could never have expected. "I want you to spank me," the prodigy says. Giving into Kazuha's desires, Kurokawa proceeds to spank the other boy, but it seems that their deal doesn't end there. As the two find more reasons to meet with each other, what will become of this unusual relationship between rivals?
