The truth
Leo's sword was continuing to clash against Prima's, but once in a while Prima's speed would win out and another small hit would be made on his body. After having removed the poison from his body, as Cindy had suggested, he was back to his usual self and was fighting at full strength. This time when attacking, he was more cautious than before.
'If I want to win this fight, I can't just treat this man as another Vampire Knight, I have to fight against him like he is a leader.'
What was strange though, was that Prima's attacks were faster after the first hit, and after a while longer of trading hits, Prima managed to get another hit on Leo's shoulder this time. Still, blood wasn't drawn, but when Prima came in thrusting multiple attacks, he was even faster than before.
