As Jotato made copies, Samurai closed his eyes his ears twitching ever so slightly, as he listained for Jotaro heartbeat, before his eyes suddenly widened and he vanished from sight, the sounds of a clear slice in the air before he reappeared behind the real Jotaro, as his horn gleamed in the light of the arena. He had used Aerial ace, an unavoidable move. (Kinda how Samurai in games do, when a clear slice causes instant death or deadly damage)
