Levy is strong, but she’s not quite ready to take on Sasuke. Sasuke was already OP back when he was a kid and his abilities have grown even more fierce since then. Sasuke can unleash his intense fire jutsu to keep Levy off balance and then finish things off in hand to hand combat. The difference in their abilities is far too vast and so this will be a pretty quick win for Sasuke. He won’t even need to go into Rinnengan mode to win this. Sasuke wins.
