Arai Kenichi (新井 健一) is a ULS Swimming School instructor who has attempted SASUKE four times, getting the farthest in his first effort. In his first tournament in SASUKE 10, he cleared the First Stage with just 0.7 seconds left. In the Second Stage, he failed the Spider Walk when he tried to exit the obstacle. It is known that he competed three more times, failing the First Stage each time. During the time of SASUKE 11, he held a SASUKE training camp with fellow competitors Hibari and Ījima Toyohisa at his house.
