I'm currently on episode 25, the episode when Saya gets her new sword and where they're analyzing Riku as he's changing into a Chiropteran. I know that Saya created Hagi, who is her Chevalier, so even though Saya's blood is poisonous to Chiropterans, wouldn't it not be affective to Hagi who already has consumed her blood once?
